Wikipedia on Sirtuins:

Sirtuin or Sir2 proteins are a class of proteins that possess either histone deacetylase or mono-ribosyltransferase activity.[2][3] Sirtuins regulate important biological pathways in bacteria, archaea and eukaryotes. The name Sir2 comes from the yeast gene 'silent mating-type information regulation 2',[4] the gene responsible for cellular regulation in yeast.

Sirtuins have been implicated in influencing aging and regulating transcription, apoptosis and stress resistance, as well as energy efficiency and alertness during low-calorie situations.[5]

Yeast Sir2 and some, but not all, sirtuins are protein deacetylases. Unlike other known protein deacetylases, which simply hydrolyze acetyl-lysine residues, the sirtuin-mediated deacetylation reaction couples lysine deacetylation to NAD hydrolysis. This hydrolysis yields O-acetyl-ADP-ribose, the deacetylated substrate and nicotinamide, itself an inhibitor of sirtuin activity. The dependence of sirtuins on NAD links their enzymatic activity directly to the energy status of the cell via the cellular NAD:NADH ratio, the absolute levels of NAD, NADH or nicotinamide or a combination of these variables.

Species distribution

Whereas bacteria and archaea encode either one or two sirtuins, eukaryotes encode several sirtuins in their genomes. In yeast, roundworms, and fruitflies, sir2 is the name of the sirtuin-type protein.[6] This research started in 1991 by Leonard Guarente of MIT.[7][8] Mammals possess seven sirtuins (SIRT1-7) that occupy different subcellular compartments such as the nucleus (SIRT1, -2, -6, -7), cytoplasm (SIRT1 and SIRT2) and the mitochondria (SIRT3, -4 and -5).

Clinical significance

Sirtuin activity is inhibited by nicotinamide, which binds to a specific receptor site,[14] so it is thought that drugs that interfere with this binding should increase sirtuin activity. Development of new agents that would specifically block the nicotinamide-binding site could provide an avenue for development of newer agents to treat degenerative diseases such as cancer, Alzheimer's, diabetes, atherosclerosis, and gout.[15][16]sitris
[edit] Alzheimer's

SIRT1 deacetylates and coactivates the retinoic acid receptor beta that upregulates the expression of alpha-secretase (ADAM10). Alpha-secretase in turn suppresses beta-amyloid production. Furthermore, ADAM10 activation by SIRT1 also induces the Notch signaling pathway, which is known to repair neuronal damage in the brain.[17]
[edit] Diabetes

Sirtuins have been proposed as a chemotherapeutic target for type II diabetes mellitus.[18]
[edit] Aging

Preliminary studies with resveratrol, a possible SIRT1 activator, have led some scientists to speculate that resveratrol may extend lifespan.[19] Further experiments conducted by Rafael de Cabo et al. showed that resveratrol-mimicking drugs such as SRT1720 could extend the lifespan of obese mice by 44%.[20] Comparable molecules are now undergoing clinical trials in humans.

Cell culture research into the behaviour of the human sirtuin SIRT1 shows that it behaves like the yeast sirtuin Sir2: SIRT2 assists in the repair of DNA and regulates genes that undergo altered expression with age.[21] Adding resveratrol to the diet of mice inhibit gene expression profiles associated with muscle aging and age-related cardiac dysfunction.[22]

A study performed on transgenic mice overexpressing SIRT6, showed an increased lifespan of about 15% in males. The transgenic males displayed lower serum levels of insulin-like growth factor 1 (IGF1) and changes in its metabolism, which may have contributed to the increased lifespan.[23]

The NAD thing mentioned above is:

Nicotinamide adenine dinucleotide, abbreviated NAD+, is a coenzyme found in all living cells. The compound is a dinucleotide, since it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide.

In metabolism, NAD+ is involved in redox reactions, carrying electrons from one reaction to another. The coenzyme is, therefore, found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD+. However, it is also used in other cellular processes, the most notable one being a substrate of enzymes that add or remove chemical groups from proteins, in posttranslational modifications. Because of the importance of these functions, the enzymes involved in NAD+ metabolism are targets for drug discovery.

In organisms, NAD+ can be synthesized from simple building-blocks (de novo) from the amino acids tryptophan or aspartic acid. In an alternative fashion, more complex components of the coenzymes are taken up from food as the vitamin called niacin. Similar compounds are released by reactions that break down the structure of NAD+. These preformed components then pass through a salvage pathway that recycles them back into the active form. Some NAD+ is also converted into nicotinamide adenine dinucleotide phosphate (NADP+); the chemistry of this related coenzyme is similar to that of NAD+, but it has different roles in metabolism.

...

Both NAD+ and NADH strongly absorb ultraviolet light because of the adenine. For example, peak absorption of NAD+ is at a wavelength of 259 nanometers (nm), with an extinction coefficient of 16,900 M−1cm−1. NADH also absorbs at higher wavelengths, with a second peak in UV absorption at 339 nm with an extinction coefficient of 6,220 M−1cm−1.[6] This difference in the ultraviolet absorption spectra between the oxidized and reduced forms of the coenzymes at higher wavelengths makes it simple to measure the conversion of one to another in enzyme assays – by measuring the amount of UV absorption at 340 nm using a spectrophotometer.[6]

NAD+ and NADH also differ in their fluorescence. NADH in solution has an emission peak at 460 nm and a fluorescence lifetime of 0.4 nanoseconds, while the oxidized form of the coenzyme does not fluoresce.[7] The properties of the fluorescence signal changes when NADH binds to proteins, so these changes can be used to measure dissociation constants, which are useful in the study of enzyme kinetics.[7][8] These changes in fluorescence are also used to measure changes in the redox state of living cells, through fluorescence microscopy.[9]

...

Nicotinamide adenine dinucleotide has several essential roles in metabolism. It acts as a coenzyme in redox reactions, as a donor of ADP-ribose moieties in ADP-ribosylation reactions, as a precursor of the second messenger molecule cyclic ADP-ribose, as well as acting as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins. In addition to these metabolic functions, NAD+ emerges as an adenine nucleotide that can be released from cells spontaneously and by regulated mechanisms[33] [34], and can therefore have important extracellular roles.[34]

...

The redox reactions catalyzed by oxidoreductases are vital in all parts of metabolism, but one particularly important area where these reactions occur is in the release of energy from nutrients. Here, reduced compounds such as glucose and fatty acids are oxidized, thereby releasing energy. This energy is transferred to NAD+ by reduction to NADH, as part of beta oxidation, glycolysis, and the citric acid cycle. In eukaryotes the electrons carried by the NADH that is produced in the cytoplasm are transferred into the mitochondrion (to reduce mitochondrial NAD+) by mitochondrial shuttles, such as the malate-aspartate shuttle.[43] The mitochondrial NADH is then oxidized in turn by the electron transport chain, which pumps protons across a membrane and generates ATP through oxidative phosphorylation.[44] These shuttle systems also have the same transport function in chloroplasts.[45]

Since both the oxidized and reduced forms of nicotinamide adenine dinucleotide are used in these linked sets of reactions, the cell maintains significant concentrations of both NAD+ and NADH, with the high NAD+/NADH ratio allowing this coenzyme to act as both an oxidizing and a reducing agent.[46] In contrast, the main function of NADPH is as a reducing agent in anabolism, with this coenzyme being involved in pathways such as fatty acid synthesis and photosynthesis. Since NADPH is needed to drive redox reactions as a strong reducing agent, the NADP+/NADPH ratio is kept very low.[46]

Although it is important in catabolism, NADH is also used in anabolic reactions, such as gluconeogenesis.[47] This need for NADH in anabolism poses a problem for prokaryotes growing on nutrients that release only a small amount of energy. For example, nitrifying bacteria such as Nitrobacter oxidize nitrite to nitrate, which releases sufficient energy to pump protons and generate ATP, but not enough to produce NADH directly.[48] As NADH is still needed for anabolic reactions, these bacteria use a nitrite oxidoreductase to produce enough proton-motive force to run part of the electron transport chain in reverse, generating NADH.[49]

The coenzyme NAD+ is also consumed in ADP-ribose transfer reactions. For example, enzymes called ADP-ribosyltransferases add the ADP-ribose moiety of this molecule to proteins, in a posttranslational modification called ADP-ribosylation.[50] NAD+ may also be added onto cellular RNA as a base modification.[51] ADP-ribosylation involves either the addition of a single ADP-ribose moiety, in mono-ADP-ribosylation, or the transferral of ADP-ribose to proteins in long branched chains, which is called poly(ADP-ribosyl)ation.[52] Mono-ADP-ribosylation was first identified as the mechanism of a group of bacterial toxins, notably cholera toxin, but it is also involved in normal cell signaling.[53][54] Poly(ADP-ribosyl)ation is carried out by the poly(ADP-ribose) polymerases.[52][55] The poly(ADP-ribose) structure is involved in the regulation of several cellular events and is most important in the cell nucleus, in processes such as DNA repair and telomere maintenance.[55] In addition to these functions within the cell, a group of extracellular ADP-ribosyltransferases has recently been discovered, but their functions remain obscure.[56]

Another function of this coenzyme in cell signaling is as a precursor of cyclic ADP-ribose, which is produced from NAD+ by ADP-ribosyl cyclases, as part of a second messenger system.[57] This molecule acts in calcium signaling by releasing calcium from intracellular stores.[58] It does this by binding to and opening a class of calcium channels called ryanodine receptors, which are located in the membranes of organelles, such as the endoplasmic reticulum.[59]

NAD+ is also consumed by sirtuins, which are NAD-dependent deacetylases, such as Sir2.[60] These enzymes act by transferring an acetyl group from their substrate protein to the ADP-ribose moiety of NAD+; this cleaves the coenzyme and releases nicotinamide and O-acetyl-ADP-ribose. The sirtuins mainly seem to be involved in regulating transcription through deacetylating histones and altering nucleosome structure.[61] However, non-histone proteins can be deacetylated by sirtuins as well. These activities of sirtuins are particularly interesting because of their importance in the regulation of aging.[62]

...

The enzymes that make and use NAD+ and NADH are important in both current pharmacology and the research into future treatments for disease.[72] Drug design and drug development exploits NAD+ in three ways: as a direct target of drugs, by designing enzyme inhibitors or activators based on its structure that change the activity of NAD-dependent enzymes, and by trying to inhibit NAD+ biosynthesis.[73]

The coenzyme NAD+ is not itself currently used as a treatment for any disease. However, it is potentially useful in the therapy of neurodegenerative diseases such as Alzheimer's and Parkinson disease.[2] Evidence on the use of NAD+ in neurodegeneration is mixed; studies in mice are promising,[74] whereas a placebo-controlled clinical trial failed to show any effect.[75] NAD+ is also a direct target of the drug isoniazid, which is used in the treatment of tuberculosis, an infection caused by Mycobacterium tuberculosis. Isoniazid is a prodrug and once it has entered the bacteria, it is activated by a peroxidase, which oxidizes the compound into a free radical form.[76] This radical then reacts with NADH, to produce adducts that are very potent inhibitors of the enzymes enoyl-acyl carrier protein reductase,[77] and dihydrofolate reductase.[78]

Since a large number of oxidoreductases use NAD+ and NADH as substrates, and bind them using a highly conserved structural motif, the idea that inhibitors based on NAD+ could be specific to one enzyme is surprising.[79] However, this can be possible: for example, inhibitors based on the compounds mycophenolic acid and tiazofurin inhibit IMP dehydrogenase at the NAD+ binding site. Because of the importance of this enzyme in purine metabolism, these compounds may be useful as anti-cancer, anti-viral, or immunosuppressive drugs.[79][80] Other drugs are not enzyme inhibitors, but instead activate enzymes involved in NAD+ metabolism. Sirtuins are a particularly interesting target for such drugs, since activation of these NAD-dependent deacetylases extends lifespan.[81] Compounds such as resveratrol increase the activity of these enzymes, which may be important in their ability to delay aging in both vertebrate,[82] and invertebrate model organisms.[83][84]

Because of the differences in the metabolic pathways of NAD+ biosynthesis between organisms, such as between bacteria and humans, this area of metabolism is a promising area for the development of new antibiotics.[85][86] For example, the enzyme nicotinamidase, which converts nicotinamide to nicotinic acid, is a target for drug design, as this enzyme is absent in humans but present in yeast and bacteria.

]All energy production in the earliest primordial times was fermentative and anaerobic. These two nutrients eventually established the basis and driving force behind reproduction for all organisms, and, consequently, behind aging and life span.

The first living cells were prokaryotic in nature; each one was identical to the next, much like bacteria, lacking a nucleus and feeding anaerobically on sugars.

Later, development of an oxygen-based atmosphere allowed for evolution into eukaryotic cells (possessing a nucleus), which allowed for cellular differentiation into organs, eyes, skin, and other tissues, making higher organisms possible. The developing presence of oxygen—essentially among the first waste products of Earth's earliest life-forms—eventually allowed for the use of fat as a nutrient for the first time. Eukaryotic cells are fueled aerobically and use fatty acids and ketones for this purpose, just as most human and other mammalian cells do today. Fat is an aerobic nutrient and forms the basis of aerobic metabolism. Herein lies the dis- tinction between the two energy sources: aerobic and anaerobic forms.

One theory of how cancers develop involves the idea that an excessively fermentative, acidic, sugar-rich, and anaerobic environment (known to be friendly to cancer growth) somehow simulates our earliest primordial environment and stimulates the reversion of some cells to their primordial, prokaryotic state. Tumors are basically masses of undifferentiated, identical cells with a weak protein matrix that feed exclusively on sugars. In other words, when the environment is ripe—when the availability of sugar is high and a fermentative, acidic, and anaerobic environment is allowed to take hold—this primordial component of our genetic makeup is somehow triggered and stimulates cells into an unhealthy, abnormal, and exceedingly primitive form of cellular proliferation. Healthy cellular differentiation cannot occur in a fermentative environment. This certainly presents a plausible model for carcinogenesis as well as other unhealthy forms of cellular proliferation.

The development of an oxygen-based atmosphere eventually allowed for the use of fat as an important energy source. In the evolution of more-complex organisms such as mammals, it is fat that serves as the primary, most efficient source of fuel. Leptin, which is the key fat sensor in the body, then controls and regulates all our energy stores via the hypothalamus, which manages the signals given to every other hormone in the body.

Evidence of the effects of caloric restriction in slowing aging and extending youth can be found in its abilities to prevent the immune dysfunctions of old age, improve DNA repair abilities, reduce damaging free-radical activity, lower glucose and insulin levels, maintain fertility at advanced ages, boost energy levels, increase protein synthesis, reduce the accumulation of damaged proteins, inhibit the inflammatory responses of aging, lower the levels of cholesterol and triglycerides in the blood, counteract neural degeneration, and prevent the age-related decline in the health-building hormone dehydroepiandrosterone (DHEA).

Caloric restriction also prevents or postpones the incidence of and reduces the severity of diseases such as cancer, kidney disease, and cardio-vascular disease (Masoro 2003).

It is also known today to be additionally important that adequate vitamins, minerals, and nutrients be supplied or added to caloric restriction approaches to avoid nutrient deficiencies. The idea is to limit calories, not nutrients (Nicolas et al. 1999). Therefore, nutrient density also plays a very important role.

Longevity enthusiasts who attempt to apply the earlier caloric restriction research by attempting to sustain themselves each day on a single kumquat and a tablespoon of oatmeal are gravely missing the point, to say nothing of living an unnecessarily stress-inducing, deprivation-oriented life. No such thing is necessary, nor is it really helping them arrive at their hoped-for objective. Recently popularized raw-food vegan diets can achieve temporary improvements by essentially down-regulating insulin and mTOR (and through such diets being generally detoxifying). The problem here is multifold, however. In addition to the fact that we as humans lack four stomachs and cud-chewing ruminant tendencies to maximize the use of plant-based foods to meet all our needs, such a diet ' completely fails to provide many essential animal-source nutrients needed, for long-term maintenance of our health, our brain, our nervous system, and our vitality. Without adequate fat to normalize leptin (among countless other things) or complete protein sources to allow for critical rebuild¬ing and maintenance, such dietary approaches ultimately do far more depletive harm than good in the long run.

Modern studies of healthy human centenarians, those people who are one hundred years old and older, have revealed the presence of a certain class of genes that seem to be activated in these individuals. Called sirtuins, they have come to be known as our longevity genes. In mammals, one of these genes is referred to as SIRT-I (in worms, it is called SIR-2 In certain fortunate people who appear to age unusually gracefully and remain vital to extremely old age, the SIRT-1 gene just sort of seems to inherently activated, for unknown lucky reasons. This is why certain lived people can claim not to have taken particular care of their health and still seem to make it to very old age. [...] Recently, a nutrient found in red wine called resveratrol was shown to have the effect of activating this gene. It has also been clearly demonstrated that calorie restriction similarly activates these genes in all organisms and has all the same beneficial effects.

[...]

The newly discovered genes are called SIRT-3 and SIRT-4. Like SIRT-1, they are part of the larger class of sirtuins. The newly discovered role of SIRT-3 and SIRT 4 confirmed the particular importance of mitochondria as vital for sustaining the health and longevity of a cell.

Mitochondria, cellular organs that are found in the cytoplasm, are often considered to be the cell's battery packs or energy-producing factories. When mitochondria become compromised by particular stressors, energy is drained out of a cell and its days are numbered. This, in turn, compromises our energy production, health, and metabolic efficiency. Sinclair and his colleagues discovered that SIRT-3 and SIRT-4 play a vital role in a longevity network that maintains the vitality of the mitochondria and keeps cells healthy when they would otherwise die. The most powerful method found of activating these life-saving and life-extending genes is caloric restriction.

When cells undergo caloric restriction, signals sent in through the cell membrane activate an enzyme called nicotinamide phosphoribosyl-transferase (NAMPT). As levels of NAMPT ramp up, a small molecule called nicotinamide adenine dinucleotide (NAD+) begins to amass in the mitochondria. This, in turn, causes the activity of enzymes created by the SIRT-3 and SIRT-4 genes—enzymes that live in the mitochondria—to increase as well. As a result, the mitochondria grow stronger, energy out¬put increases, and the cell's aging process slows down significantly.

In laboratory experiments, certain animal subjects have had their healthy life span extended by 30-60 percent—sometimes even by 300¬400 percentusing methods of optimized caloric restriction! The impli¬cations are staggering. The same basic mechanism seems to exist across all species studied, from yeast to even primates (like us).

But Why Does Caloric Restriction Work?

[...]

Insulin in these simple life-forms has nothing to do with blood sugar regulation, but instead is entirely designed to regulate reproduction and actual life span. Subsequent research has confirmed this role of insulin across all species, including primates.

How much insulin we produce over the course of our lives controls how long we live! And it turns out, the less insulin we need, the better.

Studies looking at the effects of insulin levels on human health and longevity are emerging, and the picture is quite clear. One study showed that over a ten-year period, the risk of dying was almost twice as great for people with the highest insulin levels than for those with the lowest levels. The study authors stated that excess insulin, or hyperinsulinemia, associated with increased all-cause and cardiovascular mortality, independent of other risk factors (Dekker et al. 2005). High levels of serum insulin promote high blood pressure by impairing sodium balance. Prolonged exposure to excess insulin can severely compromise the vascular system. By acting as a catalyst in promoting cellular proliferation, excess insulin also increases the risk for and progression of certain cancers. High insulin levels promote the formation of beta-amyloid in brain cells and may contribute to the development of Alzheimer's disease. Overproduction of insulin even contributes to prostate enlargement by helping to promote the overgrowth of prostate cells. Insulin resistance, a by-product of chronic excess insulin production, is associated with the development of abdominal obesity and health problems such as atherosclerosis and impotence. Furthermore, insulin resistance and obesity are risk factors for type 2 diabetes mellitus. Hyperinsulinemia is, in fact, a predictive factor for type 2 diabetes mellitus.

It turns out that insulin is an extremely ancient molecule and exists in identical form in everything from yeast cells to humans. Far from its formerly perceived, limited role in nutrient storage or even blood sugar control (a trivial sideline for insulin), insulin is now being understood as something far more important and fundamental to the very underlying mechanisms of our health and longevity. In monitoring our energy availability, while leptin oversees the actual energy stores, it is insulin that switches on and off the extremely ancient mechanisms that allow us to outlive what our body thinks is an apparent famine.

That's the clue to as to how we beat Mother Nature at her own game. The down-regulation of insulin (and mTOR) triggers the up-regulation of repair and maintenance on a cellular level that allows us to remain healthy until food becomes more available and we can finally reproduce. Bingo.

Research across the board has shown that long-lived individuals (animals and humans) share the following characteristics:

• low fasting insulin levels
• low fasting glucose levels
• optimally low leptin levels
• low triglyceride levels
• low percentage of visceral body fat
• lower body temperature
• reduced thyroid levels

Low thyroid levels, you say? Isn't that a bad thing?

The idea here is that a reduced caloric load, which results in the almost exclusive use of fat for fuel and optimal nutrient intake, improves metabolic efficiency. [...] In a human clinical study article titled "Clinical Experience of a Diet Designed to Reduce Aging," the authors remarked, "It has been stated that the reduction in T3 and body temperature could alter the aging process by reflecting a reducing metabolic rate, oxidative stress and systemic inflammation" (Rosedale et al. 2009).

{Description about a twenty-year study on the effects of caloric restriction on primates published on "Science". The primates were rhesus monkeys which are very similar to humans even in terms of diet.}

Twenty years later, only 63 percent of the monkeys that ate as much as they wanted were still alive. Thirty-seven percent of them had died from age-related causes. And the caloric-restriction group? Eighty-seven per-cent of them were still alive, and only 13 percent had died of age-related causes. Throughout their lives, the calorically restricted group maintained superior health and aging-related biomarkers in every area: brain health, metabolic health and rate, insulin sensitivity, and cardiovascular vitality. The monkeys in the caloric-restriction group enjoyed a threefold reduction in age-related disease! Also, they lost fat weight but maintained healthy levels of lean tissue mass. They also retained greater brain volume, which nor¬mally shrinks with age and glycation, but more than that, they retained superior cognitive function. The cardiovascular disease rate of the caloric-restriction group was fully half the rate of the control group. Forty percent of the monkeys in the control group developed diabetes or prediabetes. Not one single monkey in the calorically restricted group developed either.

[...]

Another area of human longevity research getting a lot of publicity these days involves manipulating the length of something called a telom-ere. Telomeres are sequences of nucleic acids extending from the ends of chromosomes that act to maintain chromosomal integrity. Every time our cells divide, telomeres are shortened, leading to cellular damage and cellular death associated with aging. Shorter telomeres have been associated with significantly higher cancer incidence. In fact, a recent Italian study showed that people with shorter telomeres have ten times the cancer risk of those with longer telomeres (and those with short telomeres were twice as likely to die from cancer) (Armanios et al. 2009).

[...]

Drug companies, of course, are looking for ways to enhance telomerase any way they can. In fact, look for other upcoming supplements and, possibly, life extension—related media¬tions claiming to do just this. What they won't tell you, however, is that caloric restriction also preserves and may even also reverse telomere length.

[If] you apply the caloric-restriction model in a way that does not leave you hungry, which is exactly what this book tells you how to do. Just follow the simple, most basic dietary guidelines outlined here to eat optimally well, and you will feel fully satisfied, live healthier and longer, and even save some real money along the way! Even while buying the best-quality produce, grass-fed meats, and wild-caught fish, you can find yourself saving considerable money on groceries. The basic guideline to remember is this: Greatly restrict or eliminate sugar and starch (preferably eliminating gluten completely); keep your protein intake adequate (roughly the RDA: 44-56 g per day or 0.8 g of protein/ kg of ideal body weight), amounting to a total of approximately 6 to 7 ounces of organic eggs, grass-fed, or wild-caught meat or seafood per day; eat as many fibrous, "aboveground," nonstarchy vegetables and greens as you like; and eat as much fat (from fattier cuts of meat or fish, nuts, seeds, avocados, coconut, butter or ghee, olives, olive oil, and other sources) as you need to satisfy your appetite. The bottom line here is that natural dietary fat is not at all our enemy and that, in the absence of dietary carbohydrate and with adequate protein, eating natural dietary fat can result in a far more satisfying, longer, and healthier life overall.

However I think there is a difference between not loosing weight and putting weight on, despite not having changed the level of carb intake. Together with my tendinitis I suspect I might have gotten myself into a more inflammatory state, which created the weight gain. Of course this is just a theory, and I'll tweak my diet slightly (as described in my post - which is probably in a beneficial direction anyway) and see what happens.

Another possibility here could be that diet isn't the cause, but rather your stress levels, sleep patterns, or other environmental changes such as having been exposed lately to greater toxicity.

Have you noticed a change in any of these?

Here:http://www.ncbi.nlm.nih.gov/pubmed/20060508
we read:

Sirtuins have emerged as important proteins in aging, stress resistance and metabolic regulation. Three sirtuins, SIRT3, 4 and 5, are located within the mitochondrial matrix. SIRT3 and SIRT5 are NAD(+)-dependent deacetylases that remove acetyl groups from acetyllysine-modified proteins and yield 2'-O-acetyl-ADP-ribose and nicotinamide. SIRT4 can transfer the ADP-ribose group from NAD(+) onto acceptor proteins. Recent findings reveal that a large fraction of mitochondrial proteins are acetylated and that mitochondrial protein acetylation is modulated by nutritional status. This and the identification of targets for SIRT3, 4 and 5 support the model that mitochondrial sirtuins are metabolic sensors that modulate the activity of metabolic enzymes via protein deacetylation or mono-ADP-ribosylation. Here, we review and discuss recent progress in the study of mitochondrial sirtuins and their targets.

Here's an article about a paper from 2009:
http://web.mit.edu/newsoffice/2009/guarente-sirtuins.html

New evidence links sirtuins and life extension
Study from Leonard Guarente shows how sirtuins act in the brain during calorie restriction to potentially lengthen lifespan.

For decades, it has been known that cutting normal calorie consumption by 30 to 40 percent can boost lifespan and improve overall health in animals such as worms and mice. Guarente believes that those effects are controlled by sirtuins — proteins that keep cells alive and healthy in the face of stress by coordinating a variety of hormonal networks, regulatory proteins and other genes.

In his latest work, published yesterday in the journal Genes and Development, Guarente adds to his case by reporting that sirtuins bring about the effects of calorie restriction on a brain system, known as the somatotropic signaling axis, that controls growth and influences lifespan length.

“This puts SIRT1 at a nexus connecting the effects of diet and the somatropic signaling axis,” says Guarente. “This is a major shot across the bow that says sirtuins really are involved in fundamental aspects of calorie restriction.”

Guarente and others believe that drugs that boost sirtuin production could help fight diseases of aging such as diabetes and Alzheimer’s, improving health in later life and potentially extending lifespan. Drugs that promote sirtuin production are now in clinical trials in diabetes patients, with results expected next year.[...]

Guarente has previously shown that calorie restriction boosts levels of a co-enzyme called NAD, which in turn activates SIRT1. That alone suggests a link between sirtuins and calorie restriction, he says, and the latest findings bolster the case.

David Sinclair, professor of pathology at Harvard Medical School and former postdoctoral associate in Guarente’s lab, says the new study fills in an important missing piece of the sirtuin puzzle — how sirtuins act in the brain to mediate the effects of calorie restriction. “Until this paper, the focus has been on tissues like muscles and liver and other organs that control metabolism.”

Sinclair is founder of a company, Sirtris, which was recently acquired by GlaxoSmithKline and is running clinical trials of sirtuin-boosting drugs.

While many scientists have embraced the idea that sirtuins are necessary to carry out the effects of calorie restriction, others are still unconvinced. Richard Miller, professor of pathology at the University of Michigan Medical School Institute of Gerontology, points out that the new study did not link SIRT1 knockout with shorter lifespan or declining health.

Notice they are trying to pharmacize it. Also, everyone in academia is not agreeing with this view. The following is from 2011:

Is The 'Longevity' Gene Sirtuin One Big Research Error?
By Catarina Amorim | September 21st 2011

A study out tomorrow in Nature by researchers from the Institute of Healthy Ageing at the University College of London and colleagues is questioning the anti-aging effects of sirtuin – which is “just”the most important anti-aging gene of the decade - claiming that its capacity to increase longevity was nothing more than an experimental error, and showing that,once the flaws are corrected, sirtuin has no effect on lifespan.

The work by Filipe Cabreiro, Camilla Burnett, Sara Valentini, David Gems and colleagues in Hungary and the US will shake the anti-aging research world, as well as the multi-million dollar industry linked to it, and it will not be easily accepted. But even if this is not the first time that some experiments are questioned, it is the first time that researchers are able to identify problems in the original experiments and show that when they are corrected the outcome is very different (and not in one, but in six of them). In other words, these new results will not be easily fought off.

Like Oscar Wilde’s "Dorian Gray" character, modern society obsesses about losing youth so much that we have turned the anti-aging industry into a multi-million dollar giant with one of the fastest growing markets in the world.

And in the last decade, sirtuin has probably been one of the industry’s biggest bets, ever since high levels of this protein were linked to longer, healthier lives in a variety of animals and it was suggested that they could be behind the increased longevity seen with calorie restriction (drastic restriction of calories, without malnutrition is known to increase longevity and retard age-related diseases).

So how did we get here, 10 years on, concluding that it is all a mistake?

The whole story starts in 1999 when it was discovered that an extra copy of the sirtuin gene increased yeasts’ longevity up to 30 %. Amazingly,a similar effect was found in a variety of different animals: fruit fly, the roundworm Caenorhabditis elegans and even mice. In roundworms,hyper-activation of the sirtuin gene was described to increase longevity are markable 50% more. But it was when sirtuins were linked to the high longevity obtained with calorie restriction that things got really exciting.

Calorie restriction increases lifespan and delay age-related diseases in a variety of organisms, including mammals and, apparently(since the experiments have not finished yet) even non-human primates, suggesting that it might also be relevant in humans. If sirtuins were behind calorie restriction, then their study could be the key to understanding our own aging, and fighting it.

To the media the idea of being able to extend life was nothing less than irresistible, but to researchers the possibility of reducing diseases associated with aging – such as diabetes, cardiovascular diseases and neuro-degeneration - was no less tempting and in 2003 the first molecule capable of activating sirtuin was found. Resveratrol is a natural ingredient of red wine and its discovery was followed by a frenetic search for synthetic equivalents (preferentially more potent) to patent and develop. By then sirtuin's potential was considered so high that the company launched by those involved in its discovery was bought by the pharmaceutical giant GlaxoSmithKlein for $720 million. Since then several synthetic equivalents of sirtuin have been found and at least one tested as far as human trials, with no conclusive results. Meanwhile anti-aging creams with red grapes extract have already been launched in the market riding on the wave of attention that grabbed the media, with even the New York Times giving sirtuins and resveratrol several main pages.

Inside the academic world another mood was stirring, with several groups starting to challenge revesratrol’s capacity to activate sirtuins among claims of artifacts and improper controls, only to have the “pro-sirtuin field” producing more supportive experiments and new explanations further rustling the field. And then, sirtuins’ effects on longevity started to be challenged too.

So what was happening, and why were scientists having such a hard time agreeing on the results?

The problem is that aging is a complex process and one very hard to study. Longevity – contrary to things like number of limbs or eye color - is not an exact number or a “yes”or “no” result, but instead a subjective measurement that can be affected by many factors with some being particularly difficult to detect like laboratory environment or inbreeding. This also means that to be able to take conclusions when it refers to longevity, the experiments, and particularly their controls, have to be flawless.

So the contradictory results regularly popping up in the sirtuin research field led Camilla Burnett, Sara Valentini, Filipe Cabreiro,David Gems and colleagues to wonder if there could be some kind of experimental design problems going on, and, finally, go back for a close and through look at the original experiments.

One of the biggest issues in this type of assays - where a gene is studied by introducing it into a species without it and then have this new population compared with control animals (animals from the same species but without the new gene) to know the function of the gene - is the confounding effect of the genetic background (the remaining genome). In fact, not only these new genes (called transgenes - genes brought from another species) tend to be carried with “activators” or “carriers” that can themselves have an effect on longevity, but also these new animals need to be bred in order have numbers enough for a statistically significant comparison, what can create problems. This comes with the fact that during the time needed to achieve enough animals, both transgenic and control populations change, losing and gaining genes as well as mutations. So when the two populations are finally compared they have many more differences than just the transgene.

The way to sort this problem is by crossing the transgenic population back with controls (this is called backcross) a few times assuring that both groups have the same genetic background (only differ in the gene to test). And this was not done in any of the original sirtuin experiments.

So to investigate if this lack could have led to errors in the experiments that launched sirtuin’s effects on longevity, Cabreiro and colleagues looked back at two of the initial transgenic roundworms - both with multiple copies of the sirtuin gene (so high quantities of sirtuin) and higher longevity – and backcrossed them several times with control animals. What they discovered is that the resulting roundworms now showed normal lifespan despite conserving high levels of sirtuin.

This basically meant that whatever was increasing longevity it was not sirtuin. In one of the transgenic worms the researchers were even able to identify the gene behind the increased longevity as a known anti-aging gene called Dyf. On one of the roundworms they also blocked the sirtuin gene to see that longevity was not affected, confirming that sirtuin had no effect on lifespan.

Next Cabreiro and colleagues tested a transgenic fruit fly – also from the original experiments - with a “switch” that hyper-activated the sirtuin gene and increased lifespan. This time, after the transgenic population was backcrossed, the resulting flies still lived longer than control animals but not than flies with only the “switch (and no sirtuin). In other words, longevity was not linked to sirtuin but, instead, to the “switch”. Confirming these results, when the researchers constructed a new transgenic fly with much higher levels of sirtuin and no “switch”, all obtained flies had a normal lifespan.

The researchers also tested resveratrol, the component of wine that supposedly activates sirtuins and is at the basis of several anti-aging products already in the market. But, despite the multiple tests done by the different laboratories using different methods, no effect of resveratrol on sirtuins could be found.

Finally they looked at one of the most interesting sirtuin experiments – the one that launched the possibility that calorie restriction worked through sirtuins – where fruit flies without sirtuin were put under calorie restriction and showed no increase in life span. When Cabreiro and colleagues backcrossed these transgenic flies with normal animals so all had the same genetic background and tested the resulting animals this time they responded to calorie restriction living longer showing that, yet again, previous results resulted from the effects of genetic background.

The conclusion, proved in this study over and over, is that sirtuins have no effect on longevity and that several of the essential experiments of the” anti-aging sirtuin theory” were wrong due to design flaws what raises the question; why did it take 11 years to detect these?

The new results will not be accepted without a fight, there is just too much at stake, and in this same edition of Nature researchers linked to some of the original experiments in worm reply accepting that they did mistakes but also claiming to have produced new transgenic roundworms that do not lose their high longevity when backcrossed. Interestingly they also refer , as proof that sirtuins work, to a published article where again no backcross was done.

Whatever happens now, and even if Glaxo and the original researchers keep pursuing the “anti-aging sirtuin theory”, its credibility has been strongly shaken. Will the anti-aging creams based on resveratrol disappear from the market? Will investors notice this article? The answer to both is “probably not”. But it will be difficult for Glaxo or any other company, to justify human trials until they can prove without doubts that sirtuin has an effect on lifespan and aging-linked diseases. This is an exciting story and one that people inside and outside of the field will no doubt be following close...

So, it appears to be not so simple after all.

Leo Galland, M.D. talks about the failures of low carb, Atkins type diets, as being due to failure to properly adjust the omega fats balance plus insulin resistance, not high insulin, per se. He says that insulin resistance, and about every other problem, is due to INFLAMMATION. He then says that Inflammation can be directly related to the level of saturated fats in the diet. He writes:

...research has shown that your degree of insulin resistance is directly related to the levels of saturated fat in your tissues, levels that are going to be higher if you're eating a lot of red meat and dairy products. ...

Overcoming insulin resistance does not result from merely lowering insulin levels ... because inflammation is in fact its root cause.

Galland then goes on to talk about all the good things in grains, fruits, veggies, spices, etc. which he thinks a person ought to be eating in order to get the vitamins etc needed to reduce inflammation. So, even though we have to reject the grains thing, maybe he's onto something with "food combining" being a key to getting the right mix of nutrients for some people with already well-advanced inflammatory problems which is the essence of auto-immune disorders?

He then says that leptin resistance is due to inflammation also saying that the best thing to do about this is to increase omega-3 fats. ...the more omega 6s you have, the more omega 3s you need to balance them.

So, basically, his solution is anti-inflammatory foods and lots of Omega 3s. And, though he also writes a whole lot of nonsense in the direction of grains and fiber and so forth, this may be an important point.



I'm curious about this Nicotinamide phosphoribosyltransferase that gets involved here. I know it's a B vitamin, but I wonder about the relationship of nicotine - chemically speaking - in relation to this topic? Can anybody find anything? (Psyche has taken a job in a Spanish hospital and will no longer be available to do research for us, so other medically/scientifically trained peeps here are gonna need to step up to the plate on this.)
 
A little addenda:

Greatly restrict or eliminate sugar and starch (preferably eliminating gluten completely); keep your protein intake adequate (roughly the RDA: 44-56 g per day or 0.8 g of protein/ kg of ideal body weight), amounting to a total of approximately 6 to 7 ounces of organic eggs, grass-fed, or wild-caught meat or seafood per day; eat as many fibrous, "aboveground," nonstarchy vegetables and greens as you like; and eat as much fat (from fattier cuts of meat or fish, nuts, seeds, avocados, coconut, butter or ghee, olives, olive oil, and other sources) as you need to satisfy your appetite.

That is actually a very small amount of protein. It amounts to about 1.5 to 2 ounces per DAY! That really is famine! You would have to eat a lot of veggies to feel satisfied. Or fat. And I'm not sure that I could eat that much fat without feeling sick.

Yes. But doing shifts and sleeping in a little room in a hospital, doing ER duty, means literally no time.

And yes, it was a bit surprising to us, but she had the offer and made the choice.
 
If I have time today, I will review the material above. I have seen it before, but I have been exposed to a lot of other material since. Nora Gedgaudas is in the minority on some of her points, but she might well be on to something. I need to be able to verify her research references. I am still wary after checking her "Coprolites of Man" reference in PBPM.

What I am seeing in the blog/podcast material from Kresser and Jaminet is that when you go VLC, with or without protein restriction, it can lead to gut flora changes that might be beneficial or harmful. It depends on the individual. Beneficial bacteria that need glucose might be killed. Harmful yeasts that can metabolize ketone bodies might increase. So while there might very well be these genetic pathways that can be activated through diet, the way to them might be booby trapped for a good many people, at least if you try to go straight to the goal.

I think it is fine to start by going VLC and seeing what happens, assuming there are no visible contraindications beforehand (as we have discussed). If it works, great -- and I do hope you will share with us the measurable results that you experience. If the results are mixed, share both sides of it. If it doesn't work for you, there are alternatives. They might or might not unlock hidden genetic capabilities, but I suspect that your chances of doing that are better if you are in generally good health, and if VLC is disrupting your gut flora or thyroid or whatever, your health may not be so good. So fix the problem if you can and then try again.

It's time for me to go shopping for the week. I am going to experiment for a while (again) with what has been called a "mild" ketogenic diet, which is around 50g/d of carbs. I didn't want to do this because I wanted to lose weight -- fast -- but after a year of trying that doesn't seem to be an option. And yet I have neurological symptoms for which a ketogenic approach is desirable, along with NAC supplementation. If nothing else, I am developing more patience.

I imagine what they're talking about is a type o fiber called inulin, or fructo-oligosaccarides (not sure if I spelled that right) which is particularly high in onions and mushrooms (as well as beans, but we'll ignore that). What feeds the good bacteria is essentially the carbohydrate that we aren't able to digest and absorb (fiber) due to the fact that we don't produce the types of enzymes needed to break the beta-bonds of the carbon chain (cellulase enzyme, among others). The real benefit of fiber is that it feeds your good bacterial populations, not that it "pushes the food through" or "scrapes impacted feces from the walls of the digestive tract", as is the popular conception. By feeding these little guys, they in-turn make important nutrients for us, including vitamin K and butyric acid (a short chain fat that the colon has actually adapted itself to use for energy since it is in the colon in abundance in a diet that includes fiber).

Hope that helps.

This is really interesting, dugdeep, and I'd like to read more. Do you remember where you read this?

Hi Foxx. I'm sorry, but I don't have a quick reference off the top of my head. I've been studying this stuff for 6+ years so a lot of it has just integrated into my general knowledge. The Wikipedia entry on inulin is pretty good (just skimmed it) and if you haven't read The Fiber Menace, that has some good info. I'm also pretty sure both Stephan Guyenet (_www.wholehealthsource.com) and Chris Masterjohn (_http://blog.cholesterol-and-health.com/) have written about bacterial fermentation and its beneficial byproducts (butyric acid, vitamin K, etc.) in the past. Sorry I can't be more help. If I had more time I'd do some research and track down some good references, but I'm swamped preparing for a class I'm teaching tomorrow all day today.

I believe that the podcast where I heard about it included one of those two people. I am going to be reading more of their material, and I may find something there even if I don't locate the podcast. The podcast reference was very brief, anyway, and I would like to have more background.

This is interesting from _http://www.doctoryourself.com/hoffer_niacin.html - although I have not read it all. Over the last week or so I have been experimenting with niacin. [References at the website]

Vitamin B-3: Niacin and Its Amide
by A. Hoffer, M.D., Ph.D.

The first water soluble vitamins were numbered in sequence according to priority of discovery. But after their chemical structure was determined they were given scientific names. The third one to be discovered was the anti-pellagra vitamin before it was shown to be niacin. But the use of the number B-3 did not stay in the literature very long. It was replaced by nicotinic acid and its amide (also known medically as niacin and its amide). The name was changed to remove the similarity to nicotine, a poison.

The term vitamin B-3 was reintroduced by my friend Bill W., co-founder of Alcoholics Anonymous, (Bill Wilson). We met in New York in 1960. Humphry Osmond and I introduced him to the concept of mega vitamin therapy. We described the results we had seen with our schizophrenic patients, some of whom were also alcoholic. We also told him about its many other properties. It was therapeutic for arthritis, for some cases of senility and it lowered cholesterol levels.

Bill was very curious about it and began to take niacin, 3 g daily. Within a few weeks fatigue and depression which had plagued him for years were gone. He gave it to 30 of his close friends in AA and persuaded them to try it. Within 6 months he was convinced that it would be very helpful to alcoholics. Of the thirty, 10 were free of anxiety, tension and depression in one month. Another 10 were well in two months. He decided that the chemical or medical terms for this vitamin were not appropriate. He wanted to persuade members of AA, especially the doctors in AA, that this would be a useful addition to treatment and he needed a term that could be more readily popularized. He asked me the names that had been used. I told him it was originally known as vitamin B-3. This was the term Bill wanted. In his first report to physicians in AA he called it "The Vitamin B-3 Therapy." Thousands of copies of this extraordinary pamphlet were distributed. Eventually the name came back and today even the most conservative medical journals are using the term vitamin B-3.

Bill became unpopular with the members of the board of AA International. The medical members who had been appointed by Bill, felt that he had no business messing about with treatment using vitamins. They also "knew" vitamin B-3 could not be therapeutic as Bill had found it to be. For this reason Bill provided information to the medical members of AA outside of the National Board, distributing three of his amazing pamphlets. They are now not readily available.

Vitamin B-3 exists as the amide in nature, in nicotinamide adenine dinucleotide (NAD). Pure nicotinamide and niacin are synthetics. Niacin was known as a chemical for about 100 years before it was recognized to be vitamin B-3. It is made from nicotine, a poison produced in the tobacco plant to protect itself against its predators, but in the wonderful economy of nature which does not waste any structures, when the nicotine is simplified by cracking open one of the rings, it becomes the immensely valuable vitamin B-3.

Vitamin B-3 is made in the body from the amino acid tryptophan. On the average 1 mg of vitamin B-3 is made from 60 mg of tryptophan, about 1.5% Since it is made in the body it does not meet the definition of a vitamin; these are defined as substances that can not be made. It should have been classified with the amino acids, but long usage of the term vitamin has given it permanent status as a vitamin. The 1.5% conversion rate is a compromise based upon the conversion of tryptophan to N-methyl nicotinamide and its metabolites in human subjects. I suspect that one day in the far distant future none of the tryptophan will be converted into vitamin B-3 and it then will truly be a vitamin. According to Horwitt [1], the amount converted is not inflexible but varies with patients and conditions. For example, women pregnant in their last three months convert tryptophan to niacin metabolites three times as efficiently as in non-pregnant females. Also there is evidence that contraceptive steroids, estrogens, stimulate tryptophan oxygenase, the enzyme that converts the tryptophan into niacin.

This observation raises some interesting speculations. Women, on average, live longer then men. It has been shown for men that giving them niacin increases their longevity. [2] Is the increased longevity in women the result of greater conversion of tryptophan into niacin under the stimulus of their increase in estrogen production? Does the same phenomenon explain the decrease in the incidence of coronary disease in women?

The best-known vitamin deficiency disease is pellagra. More accurately it is a tryptophan deficiency disease since tryptophan alone can cure the early stages. Pellagra was endemic in the southern U.S.A. until the beginning of the last world war. It can be described by the four D's: dermatitis, diarrhea, dementia and death. The dementia is a late stage phenomenon. In the early stages it resembles much more the schizophrenias, and can only with difficulty be distinguished from it. The only certain method used by early pellagrologists was to give their patients in the mental hospitals small amounts of nicotinic acid. If they recovered they diagnosed them pellagra, if they did not they diagnosed them schizophrenia. This was good for some of their patients but was not good for psychiatry since it prevented any continuing interest in working with the vitamin for their patients who did not recover fast, but who might have done so had they given them a lot more for a much longer period of time, the way we started doing this in Saskatchewan. I consider it one of the schizophrenic syndromes.

Indications
I have been involved in establishing two of the major uses for vitamin B-3, apart from its role in preventing and treating pellagra. These are its action in lowering high cholesterol levels [3] and in elevating high density lipoprotein cholesterol levels (HDL), and its therapeutic role in the schizophrenias and other psychiatric conditions. It has been found helpful for many other diseases or conditions. These are psychiatric disorders including children with learning and behavioral disorders, the addictions including alcoholism and drug addiction, the schizophrenias, some of the senile states. Its efficacy for a large number of both mental and physical conditions is an advantage to patients and to their doctors who use the vitamin, but is difficult to accept by the medical profession raised on the belief that there must be one drug for each disease, and that when any substance appears to be too effective for many conditions, it must be due entirely to its placebo effect, something like the old snake oils.

I have thought about this for a long time and have within the past year become convinced that this vitamin is so versatile because it moderates or relieves the body of the pernicious effect of chronic stress. It therefore frees the body to carry on its routine function of repairing itself more efficiently. The current excitement in medicine is the recognition that hyperoxidation, the formation of free radicals, is one of the basic damaging processes in the body. These hyperexcited molecules destroy molecules and damage tissues at the cellular level and at the tissue level.

All living tissue which depends on oxygen for respiration has to protect itself against these free radicals. Plants use one type of antioxidants and animals use another type. Fortunately there is a wide overlap and the same antioxidants such as vitamin C are used by both plants and animals. There is growing recognition that the system adrenaline -> adrenochrome plays a major role in the reactions to stress. I have elaborated this in a further report for this journal. [4]

The catecholamines, of which adrenalin is the best known example, and the aminochromes, of which adrenochrome is the best known example, are intimately involved in stress reactions. Therefore to moderate the influence of stress or to negate it, one must use compounds which prevent these substances from damaging the body. Vitamin B-3 is a specific antidote to adrenalin, and the antioxidants such as vitamin C, Vitamin E, beta carotene, selenium and others protect the body against the effect of the free radicals by removing them more rapidly from the body. Any disease or condition which is stress related ought therefore to respond to the combined use of vitamin B-3 and these antioxidants provided they are all given in optimum doses, whether small or large as in orthomolecular therapy. I will therefore list briefly the many indications for the use of vitamin B-3.

For each condition I will describe one case to illustrate the therapeutic response. For each condition I can refer to hundreds and thousands of case histories and have already in the literature described many of them in detail. [5]

Psychiatric
1) The Schizophrenias. I have reviewed this for this journal. [6]

2) Children with Learning and/or Behavioral Disorders.

In 1960 seven year-old Bruce came to see me with his father. Bruce had been diagnosed as mentally retarded. He could not read, could not concentrate, and was developing serious behavioral problems such as cutting school without his parents' knowledge. He was being prepared for special classes for the retarded. He excreted large amounts of kryptopyrrole, the first child to be tested. I started him on nicotinamide, one gram tid. Within four months he was well. He graduated from high school, is now married, has been fully employed and has been paying income tax. He is one case out of about 1500 I have seen since 1960.

Current treatment is more complicated as described in this Journal. [7]

3) Organic Confusional States, non-Alzheimers forms of dementia, electroconvulsive therapy-induced memory disturbances.

In 1954 I observed how nicotinic acid relieved a severe case of post ECT amnesia in one month. Since then I have routinely given it in conjunction with ECT to markedly decrease the memory disturbance that may occur during and after this treatment. I would never give any patient ECT without the concomitant use of nicotinic acid. It is very helpful, especially in cardiovascular-induced forms of dementia as it reverses sludging of the red blood cell and permits proper oxygenation of the cells of the body. For further information see Niacin Therapy in Psychiatry. [8]

In September 1992, Mr. C., 76 years-old, requested help with his memory. He was terribly absentminded. If he decided to do something, by the time he arrived where he wanted to do it he had forgotten what it was he wanted to do. His short-term memory was very poor and his long-term memory was beginning to be affected. I started him on a comprehensive vitamin program including niacinamide 1.5 G daily. Within a month he began to improve. I added niacin to his program. By February 1993 he was normal. April 26, 1993, he told me he had been so well he had concluded he no longer needed any niacin and decreased the dose from 3.0 G to 1.5 G daily. He remained on the rest of the program. Soon he noted that his short term memory was failing him again. I advised him to stay on the full dose the rest of his life.

4) An antidote against d-LSD,9,10 and against adrenochrome. [5]

5) Alcoholism.

Bill W. conducted the first clinical trial of the use of nicotinic for treating members of Alcoholics Anonymous. [11] He found that 20 out of thirty subjects were relieved of their anxiety, tension and fatigue in two months of taking this vitamin, 1 G tid. I found it very useful in treating patients who were both alcoholic and schizophrenic. The first large trial was conducted by David Hawkins who reported a better than 90% recovery rate on about
90 patients. Since then it has been used by many physicians who treat alcoholics. Dr. Russell Smith in Detroit has reported the largest series of patients. [12]

Physical
1. Cardiovascular
Of the two major findings made by my research group in Saskatchewan, the nicotinic acid-cholesterol connection is well known and nicotinic acid is used worldwide as an economical, effective and safe compound for lowering cholesterol and elevating high density cholesterol. As a result of my interest in nicotinic acid, Altschul, Hoffer and Stephen [3] discovered that this vitamin, given in gram doses per day, lowered cholesterol levels. Since then it was found it also elevates high density lipoprotein cholesterol thus bringing the ratio of total over HDL to below 5.

In the National Coronary Study, Canner [2] showed that nicotinic acid decreased mortality and prolonged life. Between 1966 and 1975, five drugs used to lower cholesterol levels were compared to placebo in 8341 men, ages 30 to 64, who had suffered a myocardial infarction at least three months before entering the study. About 6000 were alive at the end of the study. Nine years later, only niacin had decreased the death rate significantly from all causes. Mortality decreased 11% and longevity increased by two years. The death rate from cancer was also decreased.

This was a very fortunate finding because it led to the approval by the FDA of this vitamin in mega doses for cholesterol problems and opened up the use of this vitamin in large doses for other conditions as well. This occurred at a time when the FDA was doing its best not to recognize the value of megavitamin therapy. Its position has not altered over the past four decades.

Our finding opened up the second major wave of interest in vitamins. The first wave started around 1900 when it was shown that these compounds were very effective in small doses in curing vitamin deficiency diseases and in preventing their occurrence. This was the preventive phase of vitamin use. The second wave recognized that they have therapeutic properties not directly related to vitamin deficiency diseases but may have to be used in large doses. This was the second or present wave wherein vitamins are used in therapy for more than deficiency diseases. Our discovery that nicotinic acid was an hypocholesterolemic compound is credited as the first paper to initiate the second wave and paved the way for orthomolecular medicine which came along several years later.

2. Arthritis
I first observed the beneficial effects of vitamin B-3 in 1953 and 1954. I was then exploring the potential benefits and side effects from this vitamin. Several of the patients who were given this vitamin would report after several months that their arthritis was better. At first this was a surprise since in the psychiatric history I had taken I had not asked about joint pain. This report of improvement happened so often I could not ignore it. A few years later I discovered that Prof. W. Kaufman had studied the use of this vitamin for the arthritides before 1950 and had published two books describing his remarkable results. [13] Since that time this vitamin has been a very important component of the orthomolecular regimen for treating arthritis.

The following case illustrates both the response which can occur and the complexity of the orthomolecular regimen. Patients who are early into their arthritis respond much more effectively and are not left with residual disability.

K.V. came to my office April 15, 1982. She was in a wheelchair pushed by her husband. He was exhausted, depressed, and she was one of the sickest patients I have ever seen. She weighed under 90 pounds. She sat in the chair on her ankles which were crossed beneath her body because she was not able to straighten them out. Her arms were held in front of her, close to her body, and her fingers were permanently deformed and claw-like. She told me she had been deeply depressed for many years because of the severe pain and her major impairment. As she was being wheeled into my office I saw how ill she was and immediately concluded there was nothing I could do for her, and had to decide how I could let her know without sending her even deeper into despair. However I changed my mind when she suddenly said, "Dr. Hoffer, I know no one can ever cure me but if you could only help me with my pain. The pain in my back is unbearable. I just want to get rid of the pain in my back." I realized then she had a lot of determination and inner strength and that it was worthwhile to try and help her.

She began to suffer from severe pain in her joints in 1952. In 1957 it was diagnosed as arthritis. Until 1962 her condition fluctuated and then she had to go into a wheelchair some part of the day. She was still able to walk although not for long until 1967. In 1969 she depended on the wheelchair most of the time, and by 1973 she was there permanently. For awhile she was able to propel herself with her feet. After that she was permanently dependent on help. For the three years before she saw me she had gotten some home care but most of the care was provided by her husband. He had retired from his job when I first saw them. He provided the nursing care equivalent to four nurses on 8 hour shifts including holiday time. He had to carry her to the bathroom, bathe her, cook and feed her. He was as exhausted as she was but he was able to carry on.

She was severely deformed, especially her hands, suffered continuous pain, worse in her arms, and hips and her back. Her ankles were badly swollen and she had to wear pressure bandages. Her muscles also were very painful most of the day. She was able to feed herself and to crochet with her few useful fingers, but it must have been extremely difficult. She was not able to write nor type which she used to do with a pencil. A few months earlier she had been suicidal. On top of this severe pain and discomfort she had no appetite, was not hungry and a full meal would nauseate her. Her skin was dry, she had patches of eczema, and she had white areas in her nails.

I advised her to eliminate sugar, potatoes, tomatoes and peppers, (about 10% of arthritics have allergic reactions to the solanine family of plants). She was to add niacinamide 500 mg four times daily (following the work of W. Kaufman), ascorbic acid 500 mg four times daily (as an anti-stress nutrient and for subclinical scurvy), pyridoxine 250 mg per day (found to have anti-arthritic properties by Dr. J. Ellis), zinc sulfate 220 mg per day (the white areas in her nails indicated she was deficient in zinc), flaxseed oil 2 tablespoons and cod liver oil 1 tablespoon per day (her skin condition indicated she had a deficiency of omega 3 essential fatty acids). The detailed treatment of arthritis and the references are described in my book. [14]

One month later a new couple came into my room. Her husband was smiling, relaxed and cheerful as he pushed his wife in in her chair. She was sitting with her legs dangling down, smiling as well. I immediately knew that she was a lot better. I began to ask her about her various symptoms she had had previously. After a few minutes she impatiently broke in to say, "Dr. Hoffer, the pain in my back is all gone." She no longer bled from her bowel, she no longer bruised all over her body, she was more comfortable, the pain in her back was easily controlled with aspirin and was gone from her hips, (it had not helped before). She was cheerful and laughed in my office. Her heart was regular at last. I added inositol niacinate 500 mg four times daily to her program.

She came back June 17, 1982, and had improved even more. She was able to pull herself up from the prone position on her bed for the first time in 15 years, and she was free of depression. I increased her ascorbic acid to 1 gram four times daily and added vitamin E 800 IU. Because she had shown such dramatic improvement I advised her she need no longer come to see me.

September 1, 1982, she called me on the telephone. I asked her how she was getting along. She said she was making even more progress. I then asked her how had she been able to get to the phone. She replied she was able to get around alone in her chair. Then she added she had not called for herself but for her husband. He had been suffering from a cold for a few days, she was nursing him, and she wanted some advice for him.

After another visit October 28, 1983, I wrote to her doctor "Today Mrs. K.V. reported she had stayed on the whole vitamin program very rigorously for 18 months, but since that time had slacked off somewhat. She is regaining a lot of her muscle strength, can now sit in her wheelchair without difficulty, can also wheel herself around in her wheelchair but, of course, can not do anything useful with her hands because her fingers are so awful. She would like to become more independent and perhaps could do so if something could be done about her fingers and also about her hip. I am delighted she has arranged to see a plastic surgeon to see if something can be done to get her hand mobilized once more. I have asked her to continue with the vitamins but because she had difficulty taking so many pills she will take a preparation called Multijet which is available from Portland and contains all the vitamins and minerals and can be dissolved in juice. She will also take inositol niacinate 3 grams daily."

I saw her again March 24, 1988. About 4 of her vertebra had collapsed and she was suffering more pain which was alleviated by Darvon. It had not been possible to treat her hands surgically. She had been able to eat by herself until six months before this last visit. She had been taking small amounts of vitamins. She was able to use a motorized chair. She had been depressed. I wrote to her doctor, "She had gone off the total vitamin program about two or three years ago. It is very difficult for her to swallow and I can understand her reluctance to carry on with this. I have therefore suggested that she take a minimal program which would include inositol niacinate 3 grams daily, ascorbic acid 1 gram three times, linseed oil 2 capsules and cod liver oil 2 capsules. Her spirits are good and I think she is coming along considering the severe deterioration of her body as a result of the arthritis over the past few decades." She was last seen by her doctor in the fall of 1989.

Her husband was referred. I saw him May 18, 1982. He complained of headaches and a sense of pressure about his head present for three years. This followed a series of light strokes. I advised him to take niacin 3 grams daily plus other vitamins including vitamin C. By September 1983 he was well and when seen last March 24, 1988 was still normal.

3. Juvenile Diabetes
Dr. Robert Elliot, Professor of Child Health Research at University of Auckland Medical School is testing 40,000 five-year old children for the presence of specific antibodies that indicate diabetes will develop. Those who have the antibodies will be given nicotinamide. This will prevent the development of diabetes in most the children who are vulnerable. According to the Rotarian for March 1993 this project began 8 years ago and has 3200 relatives in the study. Of these, 182 had antibodies and 76 were given nicotinamide. Only 5 have become diabetic compared to 37 that would have been expected. Since 1988 over 20,100 school children have been tested. None have become diabetic compared to 47 from the untested comparable group. A similar study is underway in London, Ontario.

4. Cancer
Recent findings have shown that vitamin B-3 does have anti-cancer properties. This was discussed at a meeting in Texas in 1987, Jacobson and Jacobson. [15] The topic of this international conference was "Niacin, Nutrition, ADP-Ribosylation and Cancer," and was the 8th conference of this series.

Niacin, niacinamide and nicotinamide adenine dinucleotide (NAD) are interconvertable via a pyridine nucleotide cycle. NAD, the coenzyme, is hydrolyzed or split into niacinamide and adenosine dinucleotide phosphate (ADP-ribose). Niacinamide is converted into niacin, which in turn is once more built into NAD. The enzyme which splits ADP is known as poly (ADP-ribose) polymerase, or poly (ADP) synthetase, or poly (ADP-ribose) transferase. Poly (ADP-ribose) polymerase is activated when strands of deoxyribonucleic acid (DNA) are broken. The enzyme transfers NAD to the ADP-ribose polymer, binding it onto a number of proteins. The poly (ADP-ribose) activated by DNA breaks helps repair the breaks by unwinding the nucleosomal structure of damaged chromatids. It also may increase the activity of DNA ligase. This enzyme cuts damaged ends off strands of DNA and increases the cell's capacity to repair itself. Damage caused by any carcinogenic factor, radiation, chemicals, is thus to a degree neutralized or counteracted.

Jacobson and Jacobson, conference organizers, hypothesized that niacin prevents cancer. They treated two groups of human cells with carcinogens. The group given adequate niacin developed tumors at a rate only 10% of the rate in the group deficient in niacin. Dr. M. Jacobson is quoted as saying, "We know that diet is a major risk factor, that diet has both beneficial and detrimental components. What we cannot assess at this point is the optimal amount of niacin in the diet... The fact that we don't have pellagra does not mean we are getting enough niacin to confer resistance to cancer." About 20 mg per day of niacin will prevent pellagra in people who are not chronic pellagrins. The latter may require 25 times as much niacin to remain free of pellagra.

Vitamin B-3 may increase the therapeutic efficacy of anti-cancer treatment. In mice, niacinamide increased the toxicity of irradiation against tumors. The combination of normobaric carbogen with nicotinamide could be an effective method of enhancing tumor radiosensitivity in clinical radiotherapy where hypoxia limits the outcome of treatment. Chaplin, Horsman and Aoki16 found that nicotinamide was the best drug for increasing radiosensitivity compared to a series of analogues. The vitamin worked because it enhanced blood flow to the tumor. Nicotinamide also enhanced the effect of chemotherapy. They suggested that niacin may offer some cardioprotection during long-term adriamycin chemotherapy.

Further evidence that vitamin B-3 is involved in cancer is the report by Nakagawa, Miyazaki, Okui, Kato, Moriyama and Fujimura [17] that in animals there is a direct relationship between the activity of nicotinamide methyl transferase and the presence of cancer. Measuring the amount of N-methyl nicotinamide was used to measure the activity of the enzyme. In other words, in animals with cancer there is increased destruction of nicotinamide, thus making less available for the pyridine nucleotide cycle. This finding applied to all tumors except the solid tumors, Lewis lung carcinoma and melanoma B-16.

Gerson [18] treated a series of cancer patients with special diets and with some nutrients including niacin 50 mg 8 to 10 times per day, dicalcium phosphate with vitamin D, vitamins A and D, and liver injections. He found that all the cancer cases were benefited in that they became healthier and in many cases the tumors regressed. In a subsequent report Gerson elaborated on his diet. He now emphasized a high potassium over sodium diet, ascorbic acid, niacin, brewers yeast and lugols iodine. Right after the war there was no ready supply of vitamins as there is today. I would consider the use of these nutrients in combination very original and enterprising. Dr. Gerson was the first physician to emphasize the use of multivitamins and some multiminerals. More details are
in Hoffer. [19]

Additional evidence that vitamin B-3 is therapeutic for cancer arises from the National Coronary Study, Canner. [2]

5. Concentration Camp Survivors
In 1960 I planned to study the effect of nicotinic acid on a large number of aging people living in a sheltered home. A new one had been built. I approached the director of this home, Mr. George Porteous. I arranged to meet him and told him what I would like to do and why. I gave him an outline of its properties, its side effects and why I thought it might be helpful. Mr. Porteous agreed and we started this investigation. A short while after my first contact Mr. Porteous came to my office at University Hospital. He wanted to take nicotinic acid himself, he told me, so that he could discuss the reaction more intelligently with people living in his institution. He wanted to know if it would be safe to do so.

That fall he came again to talk to me and this time he said he wanted to tell me what had happened to him. Then I discovered he had been with the Canadian troops who had sailed to Hong Kong in 1940, had been promptly captured by the Japanese and had survived 44 months in one of their notorious prisoner of war camps.

Twenty-five percent of the Canadian soldiers died in these camps. They suffered from severe malnutrition from starvation and nutrient deficiency. They suffered from beri beri, pellagra, scurvy, infectious diseases, and brutality from the guards.

Porteous, a physical education instructor, had been fit weighing about 190 pounds when he got there. When he returned home he weighed only 2/3rds of that. On the way home in a hospital ship the soldiers were fed and given extra vitamins in the form of rice polishings. There were few vitamins available then in tablets or capsules. He seemingly recovered but had remained very ill. He suffered from both psychological and physical symptoms. He was anxious, fearful and slightly paranoid. Thus, he could never be comfortable sitting in a room unless he sat facing the door. This must have arisen from the fear of the guards. Physically he had severe arthritis. He could not raise his arms above his shoulders. He suffered from heat and cold sensitivity. In the morning he needed his wife's help in getting out of bed and to get started for the day. He had severe insomina. For this he was given barbiturates in the evening and to help awaken him in the morning, he was given amphetamines.

Later I read the growing literature on the Hong Kong veterans and there is no doubt they were severely and permanently damaged. They suffered from a high death rate due to heart disease, crippling arthritis, blindness and a host of other conditions.

Having outlined his background he then told me that two weeks after he started to take nicotinic acid, 1 gram after each meal, he was normal. He was able to raise his arms to their full extension, and he was free of all the symptoms which had plagued him for so long. When I began to prepare my report [20] I obtained his Veterans Administration Chart. It came to me in two cardboard boxes and weighed over ten pounds, but over 95% of it was accumulated before he started on the vitamin. For the ten years after he started on the vitamin there was very little additional material. One could judge the efficacy of the vitamin by weighing the chart paper before and after he started on it. Porteous remained well as long as he stayed on the vitamin until his death when he was Lieutenant Governor of Saskatchewan. In 1962, after having been well for two years, he went on a holiday to the mountains with his son and he forgot to take his nicotinic acid with him. By the time he returned home almost the entire symptomatology had returned.

Porteous was enthusiastic about nicotinic acid and began to tell all his friends about it. He told his doctor. His doctor cautioned him that he might damage his liver. Porteous replied that if it meant he could stay as well as he was until he died from a liver ailment he would still not go off it. His doctor became an enthusiast as well and within a few years had started over 300 of his patients on the vitamin. He never saw any examples of liver disease from nicotinic acid.

I have treated over 20 prisoners from Japanese camps and from European concentration camps since then with equally good results. I estimated that one year in these camps was equivalent to 4 years of aging, i.e. four years in camp would age a prisoner the equivalent of 16 years of normal living.

George Porteous wanted every prisoner of war from the eastern camps treated as he had been. He was not successful in persuading the Government of Canada that nicotinic acid would be very helpful so he turned to fellow prisoners, both in Canada (Hong Kong Veterans) and to American Ex-Prisoners of War. These American veterans suffered just as much as had the Canadian soldiers since they were treated in exactly the same abysmal way. The ones who started on the vitamin showed the same response. Recently one of these soldiers, a retired officer, wrote to me after being on nicotinic acid 20 years that he felt great, owed it to the vitamin and that when his arteries were examined during a simple operation they were completely normal. He wrote, "About two years ago, I was hit, was bleeding down the neck. The MDs took the opportunity to repair me. They said the arteries under the ears look like they had never been used."

There is an important lesson from the experiences of these veterans and their response to megadoses of nicotinic acid. This is that every human exposed to severe stress and malnutrition for a long enough period of time will develop a permanent need for large amounts of this vitamin and perhaps for several others.

This is happening on a large scale in Africa where the combination of starvation, malnutrition and brutality is reproducing the conditions suffered by the veterans. Those who survive will be permanently damaged biochemically, and will remain a burden to themselves and to the community where they live. Will society have the good sense to help them recover by making this vitamin available to them in optimum doses?

Doses
The optimum dose range is not as wide as it is for ascorbic acid, but it is wide enough to require different recommendations for different classes of diseases. As is always the case with nutrients, each individual must determine their own optimum level. With nicotinic acid this is done by increasing the dose until the flush (vasodilation) is gone, or is so slight it is not a problem.

One can start with as low a dose as 100 mg taken three times each day after meals and gradually increase it. I usually start with 500 mg each dose and often will start with 1 gram per dose especially for cases of arthritis, for schizophrenics, for alcoholics and for a few elderly patients. However, with elderly patients it is better to start small and work it up slowly.

No person should be given nicotinic acid without explaining to them that they will have a flush which will vary in intensity from none to very severe. If this is explained carefully, and if they are told that in time the flush will not be a problem, they will not mind. The flush may remain too intense for a few patients and the nicotinic acid may have to be replaced by a slow release preparation or by some of the esters, for example, inositol niacinate. The latter is a very good preparation with very little flush and most find it very acceptable even when they were not able to accept the nicotinic acid itself. It is rather expensive but with quantity production the price might come down.

The flush starts in the forehead with a warning tingle. Then it intensifies. The rate of the development of the flush depends upon so many factors it is impossible to predict what course it will follow.

The following factors decrease the intensity of the flush: a cold meal, taking it after a meal, taking aspirin before, using an antihistamine in advance.

The following factors make the flush more intense: a hot meal, a hot drink, an empty stomach, chewing the tablets and the rate at which the tablets break down in liquid.

From the forehead and face the flush travels down the rest of the body, usually stopping somewhere in the chest but may extend to the toes. With continued use the flush gradually recedes and eventually may be only a tingling sensation in the forehead. If the person stops taking the vitamin for a day or more the sequence of flushing will be re-experienced. Some people never do flush and a few only begin to flush after several years of taking the vitamin. With nicotinamide there should be no flushing but I have found that about 2% will flush. This may be due to rapid conversion of the nicotinamide to nicotinic acid in the body.

When the dose is too high for both forms of the vitamin the patients will suffer from nausea at first, and then if the dose is not reduced it will lead to vomiting. These side effects may be used to determine what is the optimum dose. When they do occur the dose is reduced until it is just below the nausea level. With children the first indication may be loss of appetite. If this does occur the vitamin must be stopped for a few days and then may be resumed at a lower level. Very few can take more than 6 grams per day of the nicotinamide. With nicotinic acid it is possible to go much higher. Many schizophrenics have taken up to 30 grams per day with no difficulty. The dose will alter over time and if on a dose where there were no problems, they may develop in time. Usually this indicates that the patient is getting better and does not need as much. I have divided all patients who might benefit from vitamin B-3 into the following categories.

Category 1. These are people who are well or nearly well, and have no obvious disease. They are interested in maintaining their good health or in improving it. They may be under increased stress. The optimum dose range varies between 0.5 to 3 grams daily. The same doses apply to nicotinamide.

Category 2. Everyone under physiological stress, such as pregnancy and lactation, suffering from acute illness such as the common cold or flu, or other diseases that do not threaten death. All the psychiatric syndromes are included in this group including the schizophrenias and the senile states. It also includes the very large group of people with high blood cholesterol levels or low HDL when it is desired to restore these blood values to normal. The dose range is 1 gram to 10 grams daily. For nicotinamide the range is 1 1/2 g to 6 g.

Nicotinamide does not affect cholesterol levels.

Side Effects
Here are Dr. John Marks' conclusions. [21]

"A tingling or flushing sensation in the skin after relatively large doses (in excess of 75 mg) of nicotinic acid is a rather common phenomenon. It is the result of dilation of the blood vessels that is one of the natural actions of nicotinic acid and one for which it is used therapeutically. Whether this should therefore be regarded as a true adverse reaction is a moot point. The reaction clears regularly after about 20 minutes and is not harmful to the individual. It is very rare for this reaction to occur at less than three times the RDA, even in very sensitive individuals. In most people much larger quantities are required. The related substance nicotinamide only very rarely produces this reaction and in consequence this is the form generally used for vitamin supplementation.

"Doses of 200 mg to 10 g daily of the acid have been used therapeutically to lower blood cholesterol levels under medical control for periods of up to 10 years or more and though some reactions have occurred at these very high dosages, they have rapidly responded to cessation of therapy, and have often cleared even when therapy has been continued.

"In isolated cases, transient liver disorders, rashes, dry skin and excessive pigmentation have been seen. The tolerance to glucose has been reduced in diabetics and patients with peptic ulcers have experienced increased pain. No serious reaction have been reported however even in these high doses. The available evidence suggests that 10 times the RDA is safe (about 100 mg)."

Dr. Marks is cautious about recommending that doses of 100 mg are safe. In my opinion, based upon 40 years of experience with this vitamin the dose ranges I have recommended above are safe. However with the higher doses medical supervision is necessary.

Jaundice is very rare. Fewer that ten cases have been reported in the medical literature. I have seen none in ten years. When jaundice dose occur it is usually an obstructive type and clears when the vitamin is discontinued. I have been able to get schizophrenic patients back on nicotinic acid after the jaundice cleared and it did not recur.

Four serious cases have been reported, all involving a sustained release preparation. Mullin, Greenson & Mitchell (1989) [22] reported that a 44 year-old man was treated with crystalline nicotinic acid, 6 grams daily, and after 16 months was normal. He then began to take a sustained-release preparation, same dose. Within three days he developed nausea, vomiting, abdominal pain, dark urine. He had severe hepatic failure and required a liver transplant. Henkin, Johnson & Segrest found three patients who developed hepatitis with sustained release nicotinic acid. When this was replaced with crystalline nicotinic acid there was no recurrent liver damage. [23]

Since jaundice in people who have not been taking nicotinic acid is fairly common it is possible there is a random association. The liver function tests may indicate there is a problem when in fact there is not. Nicotinic acid should be stopped for five days before the liver function tests are given. One patient who had no problem with nicotinic acid for lowering cholesterol switched to the slow release preparations and became ill. When he resumed the original nicotinic acid he was well again with no further evidence of liver dysfunction. I have not seen any cases reported anywhere else. I have described much more fully the side effects of this vitamin elsewhere. [24]

Inositol hexaniacinate is an ester of inositol and nicotinic acid. Each inositol molecule contains six nicotinic acid molecules. This ester is broken down slowly in the body. It is as effective as nicotinic acid and is almost free of side effects. There is very little flushing, gastrointestinal distress and other uncommon side effects. Inositol, considered one of the lesser important B vitamins, does have a function in the body as a messenger molecule and may add something to the therapeutic properties of the nicotinic acid.

Conclusion
Vitamin B-3 is a very effective nutrient in treating a large number of psychiatric and medical diseases but its beneficial effect is enhanced when the rest of the orthomolecular program is included. The combination of vitamin B-3 and the antioxidant nutrients is a great anti-stress program.
