What is Bio-Identical Progesterone?
The USP progesterone used for hormone replacement is extracted from a very specific type of wild yam that grows in Mexico, or from soybeans. In the laboratory this substance is chemically synthesized into real human progesterone. Progesterone is a highly fat-soluble compound exceedingly well absorbed when applied transdermally or onto the skin. According to hormone researcher David Zava, Ph.D., progesterone is by far the most lipophilic, or fat-loving, of the steroid hormones.
