Hi @dani, thank you for sharing your knowledge, very interesting. I have several friends who have started hormonal replacement therapy (estradiol), and have done some research on it, especially since the C’s confirmed that hormone replacement therapy is generally a good idea (session of 6th July 2024).
I came across this interview of Dr. Mercola with Kashif Khan of 6th August 2023. He is the founder and CEO of The DNA Company (I understand that he is not a medical doctor), and he wrote a book ‘The DNA Way.’
According to Mercola, Khan is quite knowledgeable in the area of endotoxin and mycotoxin, which can play an important role in many chronic degenerative diseases, and estrogen excess, which can produce symptoms identical to endotoxin. I would be interested in your opinion about what he has to say, especially since he strongly recommends avoiding estrogen replacement therapy as most women are prescribed estradiol, typically, which he says converts into 4-hydroxy estrogen, a cancer fuel. Also, what is your opinion about his suggestion to take pregnenolone instead? Here are some excerpts from the transcription of the interview:
Khan explains:
FWIW, I also include this article from another Menopause thread, about the many, many different symptoms women deal with, which reveals a lack of comprehensive understanding among health care providers and women themselves, so by all means, dani, please do write that book !

Khan explains:
While estrogen replacement therapy is all the rage, this strategy is likely doing far more harm than good. I strongly recommend avoiding estrogen replacement therapy, even bioidentical, organic estrogen replacement therapy. You can go on other forms of hormone therapy, but not estrogen.
[Estrogen] is certainly one of our biggest toxic threats today, especially given that you have to think of it contextually. Our context today is not grandma's context. [Due to] the hormone disruption and estrogen mimics we're dealing with [today], you already have too much, and you’re adding more through hormone replacement therapy or birth control pills.
So, we're already in a context where it's a threat, so you have to pay attention to it. The layers you have to look at are dominance. So, what do I make? Am I more androgenized, am I more estrogenized? And you can predict that through the genes that metabolize each step of the cascade ... progesterone to testosterone, to estrogen. What do I do in each one of those steps?
Many women — and men, by the way — are estrogen-dominant and just produce way too much. It's [due to] a conversion of CYP19A1 to testosterone and estrogen. That's why aromatase-inhibitor inhibitors work well, because you are just flowing the gene expression down in that one location, and all of a sudden, you have more free flowing testosterone.
By the way, there are three pathways that your estrogens convert into, potentially, before you clear them, and these metabolites are 2-, 4- and 16-hydroxy estrogen. 2-hydroxy estrogen is the good clean stuff you want. 4- and 16-hydroxy estrogen are toxic.
… But these two metabolites, the 4 and 16 [are] highly inflammatory, [and] we know all chronic conditions are rooted in inflammation. For men, the 16-hydroxy pathway is closely connected to testicular cancer. In the androgen pathway, dihydrotestosterone fuels prostate cancer."
To detox estrogen, the same detox pathways used for other toxins also apply here, such as the glutathione pathway, antioxidation, superoxide dismutase and COMT, which is the tail end of methylation. COMT, in particular, is really important for clearing toxic estrogens, whereas glucuronidation deals with some of the androgen toxins.
"If you take a hormone therapy and look at this cascade, what are most women getting? They're getting estradiol, typically, which converts into 4-hydroxy estrogen, which is a cancer fuel.
…Keep in mind, in menopause you don't have a menstrual cycle anymore, so you're not clearing that toxin. It just gets stored in fat. That's what your body does with it, which is why you have inflammation in the breast. That's where you have a lot of fat as a woman.
How to Measure Estrogen Excess
There are two ways to measure or gauge potential estrogen excess. One is to look at your genetics to understand how you metabolize estrogen. The other is to take a standard DUTCH test, which is commonly used to monitor patients on hormone replacement therapy.
Unfortunately, many doctors are not trained on interpreting metabolites. They're looking at estrogen alone, not understanding that there are genes that metabolize and turn the estrogen into different things.
I'm not opposed to all hormone replacement therapy. The master precursor hormone, though, is pregnenolone. That is the base hormone that converts to all others, and it’s unlikely to aromatize. The ideal administration route is once a day in a cacao butter suppository. DHEA, which is a male hormone, at 5 to 10 mg can also be added.
… DHEA can easily aromatize and can form estrogen, which is not a good thing, so you need to be careful about using too much. Those are two base hormones that people can use rather safely. You can also use progesterone, which is anti-estrogen.
Estrogen, aside from increasing intracellular calcium concentration, is also antimetabolic, as it slows down your metabolic rate and inhibits your thyroid function, both of which are bad news. It’s toxic to your body in most cases. It is likely only second to excess LA intake as a factor that increases your risk of cancer.
You do need it sometimes, certainly for reproductive purposes and for wound healing, but most of the time you have more than enough to fill those roles, and it's just an excess, especially with all the xenoestrogens we're exposed to in the food supply.
