The Effects of Bio-Identical Hormones

by Leila Turner, ND, Contributor to Naturopathy on

Because bioidentical hormones are identical in structure to our own body’s sex hormones, their actions are relatively gentle and effective. Bioidentical natural hormones attach themselves to the human cell binding sites, which are areas on the cell surface that specifically recognize substances cells need to use in order to maintain their healthy function. Estrogen and progesterone receptors recognize bioidentical hormones (taken as prescription) the same way that they recognize hormones produced naturally by our own human bodies. Natural, bioidentical hormones are derived from a plant molecule called diosgenin found in soybeans and wild yams. After diosgenin is extracted from these plants, it is converted into bioidentical progesterone in the laboratory. In turn, progesterone can be converted by a chemist into the three human estrogen hormones: estradiol(E2), estrone (E1), and estriol (E3).

Symptoms of hormonal imbalances occur as we get older due to deficiencies or lack of main female hormones in our body after menopause: estrogen and progesterone. These deficiencies require replacement in order for the imbalance to be righted and symptoms to be resolved. In our body, natural hormones act directly to target the root cause of hormone deficiency symptoms.

The 2008 evidence-based position statement regarding recommendations for menopausal hormone therapy (HT; refers to both estrogen alone and estrogen plus progesterone) for postmenopausal women, published by The North American Menopause Society (NAMS), considers the current best practice of medicine from a clinical perspective. The undue fear and confusion generated in recent years by overrepresentation or misinterpretation of clinical studies mandates a clearer explanation of the therapeutic benefit-risk ratio of HT at various times through menopause and beyond, and how these benefits and risks impact both health providers and the women weighing the use of such therapy.

From another article on Care2 about bio-identical hormones:
How do we know all these medical authorities condemning bio-identical hormones aren’t just in the pockets of drug companies that don’t want the competition? After all, there are literally billions of dollars at stake. Whenever I’m skeptical I turn to The Medical Letter on Drugs and Therapeutics, considered one of the least biased sources in medicine. It’s kind of like the Consumer Reports of the drug world—and, in fact, was actually co-founded by the co-founder of the publisher of Consumer Reports more than 50 years ago. As The Medical Letter likes to brag on their website, they do not accept grants (from any source), donations (from anyone), or funding (from any entity). They won’t let their work be used for promotional purposes and they don’t accept any advertising.

The Medical Letter on Drugs and Therapeutics recently reviewed bio-identical hormones and came to the same conclusion: “There is no acceptable evidence that bio-identical hormones are safe or effective. Patients should be discouraged from taking them.”

I was on a Bio- identical called activella, which is the number one HRT prescribed throughout the UK, and I had NOT one side effect from it so if you need to do HRt, definitely go with a bio-identical!

Thank you! Where does one purchase these? I think I really need something. My male doctor keeps saying I'm past menopause so why worry? I feel like I've been hit by a truck some days. And I'm not old enough for Medicare and not poor enough for Medicaid and have temporary work. So if someone can identify a source near DC I would appreciate it.

I am currently on bio-identical hormone replacement, and I feel sooo much better. I believe it is a no-brainer: your hormonal levels decrease as you age, and you are replacing them the natural way. However, that said, Ii am closely monitored, and have bloodwork done every 3 months to check my levels and determine if any adjustments with the dosages are needed. The thyroid should not be avoided - it produces the hormones which control all of the other hormoes--the body's barometer, so to speak...
