Why use biologically identical (natural) hormones?
Hormones are specialized molecules secreted by the endocrine glands. There are several different kinds and they exert their effects on target cells located away from their site of production. When we replace missing or deficient hormones such as estrogens or progesterone it is very important that we stay true to the original molecular structure of the hormone being replaced. This is called replacement with biologically identical hormones or natural hormones. If the structure of the hormone being replaced is altered or modified, then there will be side effects not seen with the original hormone. For example Provera, which is modified progesterone is a component of Prempro, is a popular hormone replacement for menopausal women. Provera has a number of problems associated with it’s use such as bloating, mood swings, bleeding, blood clots, and increased risk for strokes and heart attacks. Progesterone has none of these problems hence the importance of replacing missing or deficient hormone
