I was just reading some recommended threads about Candida on Curezone - 'Candida & Candidiasis: The Yeast Infection Syndrome Forum', ( _http://curezone.com/forums/s.asp?f=460&ob=d&c=4) There was an interesting posting about glutathione(direct link to entire thread is: _http://curezone.com/forums/fm.asp?i=1243481#i).
Now I know this is kind of repetition from my earlier post, and you guys have brought up glutathione earlier, but in the Curezone-post there's many good references to more interesting studies on the subject and I really think it's essential to see and go through those "official" studies to get some valuable information. In most cases, when searching for the studies, you can just read the summary - but that's often all you need (and can understand!). It's amazing how much actually has been researched about these things!
Following the last link above there's references to more studies:

Glutathione deficiency has been found to be virtually universal in autoimmune diseases. This deficiency has two major implications: detox failure and viral/microbial activation. Glutathione plays a major role in detoxification. This deficiency impairs the body’s ability to get rid of toxins.
Consequently, people slowly become toxic, storing away poisons in fatty tissue, muscles, organs and the brain. This cellular detox failure can make people canaries to their environment.
To detoxify successfully, this glutathione deficiency must be addressed.
Because glutathione is a potent antiviral and anti-microbial weapon, glutathione deficiency compromises antiviral and anti-microbial defenses, and actually stimulates viral replication. Raising glutathione levels inside the cells can stop the replication of almost any pathogen.
A glutathione deficiency compromises our ability to keep old viruses dormant and fight off bacteria. This is why so many people test positive for EBV, CMV, HHV6, Mycoplasma, and Chlamydia Pneumoniae, etc.
Indications are that glutathione can stop the replication of any intracellular microbe, including HHV6, Chlamydia Pneumoniae, and mycoplasma. Dr. Cheney found that some of his patients were becoming virus free after using a glutathione-creating undenatured whey protein for approximately 6 months. Showing that the increased levels of glutathione were indeed able to handle the viral infections.
There has been a good deal of research that show how important glutathione is.
Immune depressed individuals have lower glutathione levels when fighting disease. Lymphocytes, cells vital for your immune response, depend on glutathione for their proper function and replication. Immunology 61: 503-508 1987 .
Cellular depletion of Glutathione has been implicated as a causative, or contributory factor in many pathologies including Parkinson's, Alzheimer's, cataracts, arteriosclerosis, cystic fibrosis, malnutrition, aging, AIDS and cancer (Bounous et al., 1991).
In addition, Glutathione is essential in supporting the immune system, including natural killer cells (Droege et al., 1997) and in the maintenance of T-lymphocytes (Gutman, 1998).
It is known that as we age, there is a precipitous drop in glutathione levels. Lower Glutathione levels are implicated in many diseases associated with aging, including Cataracts, Alzheimer's disease, Parkinson's, atherosclerosis and others. Journal of Clinical Epidemiology 47: 1021-28 1994
Antioxidants are well documented to play vital roles in health maintenance and disease prevention. Glutathione is our cell's own major antioxidant. Why not use what is natural? Biochemical Pharmacology 47:2113-2123 1994
Low glutathione has been demonstrated in neurodegenerative diseases such as MS (Multiple Sclerosis), ALS (Lou Gehrig's Disease), Alzheimer's, and Parkinson's, among others. The Lancet 344: 796-798 1994
Glutathione detoxifies many pollutants, carcinogens and poisons, including many in fuel exhaust and cigarette smoke. It retards damage from radiation such as seen with loss of the ozone. Annual Review of Biochemistry 52: 711-780 1983.
The liver is the main detoxification organ of the body. In the liver we find very high concentrations of glutathione, as it is a major factor in numerous biochemical detoxification pathways. Numerous studies have demonstrated that patients with compromised liver function due to alcohol abuse have significant reduction of glutathione in the liver. (Lamestro, 1995)
Glutathione is essential for the maintenance of Vitamin C and vitamin E levels according to Martensson. He found that as glutathione levels decreased, a corresponding decrease in ascorbic acid and vitamin E followed, which led to systematic mitochondrial death, which in turn leads to a cessation of cellular metabolism.
(It is this mitochondrial death, at first just a dysfunction, that may cause the fatigue found in autoimmune illnesses.)
The over-toxicity causes extensive free radical damage. Inhibits cellular function. Disrupts energy production by the mitochondria. Consequently the primary energy the cells produce is anaerobic which leads to extensive lactic acid buildup in the cells. And more toxicity.
Cheney explains that fatigue becomes worse. Pain increases. You feel sicker. Memory suffers as toxins and free radicals damage the brain, and not enough oxygen gets into the brain. Deep brain structures like the hypothalamus eventually are injured and cause problems with virtually every hormone in your body. They lose their ability to rise and fall according to signals or demands from the body making it harder to respond to changing situations. Actual damage to the DNA of the energy producing mitochondria can occur. Further limiting energy.
As toxins cause free radical damage, you end up with low levels of all the free radical scavengers. They get used up dealing with excessive free radicals produced by the excessive toxins.
Some researchers believe that supplements other than oral glutathione may be more effective in raising blood levels of glutathione. For example, in one trial, blood glutathione levels rose nearly 50% in healthy people taking 500 mg of vitamin C per day for only two weeks.10 Vitamin C raises glutathione by helping the body manufacture it. In addition to vitamin C, other nutritional compounds that may, according to preliminary research, help increase glutathione levels include alpha lipoic acid,11 glutamine,12 methionine,13 S-adenosyl methionine (SAMe),14 and whey protein.15 Vitamin B6, riboflavin, and selenium are required in the manufacture of glutathione. The extent to which any of these nutrients effectively increases glutathione levels in humans remains unclear.

Per serving, asparagus, avocadoes, asparagus, squash, okra, cauliflower, broccoli, potatoes, spinach, walnuts, garlic, and raw tomatoes have the highest glutathione content compared to other vegetables and are particularly rich dietary sources of glutathione.

Glutathione (GSH) is an antioxidant and detoxifying agent whose protective role has been demonstrated in numerous clinical studies. GSH is synthesized rapidly in the liver, kidneys, and other tissues of the body, including the gastrointestinal tract. This process is effected by aging and disease, as both of these conditions result in reduced tissue and blood levels of glutathione. Dietary forms of glutathione are efficiently absorbed into the blood, however the same is not true for glutathione supplements in humans. When healthy subjects were given a single dose of up to 3,000 mg of glutathione researchers found there was no increase in blood glutathione levels. (Witschi A, Reddy S, Stofer B, Lauterburg BH. The systemic availability of oral glutathione. Eur J Clin Pharmacol 1992;43(6):667-9.) The authors of this study concluded "it is not feasible to increase circulating glutathione to a clinically beneficial extent by the oral administrating of a single dose of 3 g of glutathione." Johnson and coworkers (Johnston CJ, Meyer CG, Srilakshmi JC. Vitamin C elevates red blood cell glutathione in healthy adults. Am J Clin Nutr 58:103-5, 1993) found that blood glutathione levels rose nearly 50% in healthy individuals taking 500 mg of vitamin C daily. Vitamin C facilitates an increase in blood glutathione levels by supplying the body with a nutrient that is critical to the manufacture of it.
In addition, to vitamin C, dietary sources of glutathione and several other nutritional compounds can help increase glutathione levels including N-acetylcysteine (NAC), alpha-lipoic acid, glutamine, methionine, and undenatured whey protein (Bounous, G., and Gold, P., The biological activity of undenatured dietary whey proteins [Immunocal]: role of glutathione, Clin. Invest. Med. (1991) 14(4):296-309.). N-acetylcysteine has been used in combination with glutamic acid (or glutamine) and glycine (Clark, J. at _www.cfsn.com) and in addition, NAC has been studied in combination with dietary proteins (Quig, D., Cysteine metabolism and metal toxicity, Alternative Medicine Review (1998) 3(4):262-270.).
