Progestins and Natural Progesterone Are Not the Same!
There is a great deal of confusion about progesterone among both healthcare practitioners and their patients. Many practitioners think that commonly prescribed progestins such as Provera® are natural progesterone or that natural progesterone is a progestin. In reality, progestins are chemicals that have been synthesized from natural progesterone and whose chemical structures have been altered. While progestins can have a few of the positive effects of natural progesterone, they can also have unwanted side effects such as allergic reactions, acne, edema, hair loss, fatigue and nervousness, to name a few.
In addition, Dr. Lee concluded that progestins can bind to progesterone receptors within cells and thereby inhibit the action of the natural hormone. He also concluded that traditional hormone replacement therapy — which combines estrogens with a progestin — was only marginally effective for treating osteoporosis and could cause heart disease, breast cancer and strokes. Dr. Lee’s findings were confirmed in 2002 by the Women’s Health Initiative study, which showed increased incidents of these diseases among women taking Premarin and Provera (PremPro).
For all of the above reasons, Dr. Lee recommended natural progesterone instead of progestins when hormone level tests indicate the need for progesterone supplementation.
