The term "natural" is confusing when it is used in connection with hormones. When we say a hormone is "natural", we are referring to the molecules that make up the structure of the hormone. A natural hormone has a chemical structure that is identical to the hormone naturally produced by the body, which is why natural hormones are also called "bioidentical" hormones.

A "natural" hormone does not mean that it is an organic product purchased in a health food store. In fact, many "natural" hormones are synthesized in laboratories using pharmaceutical-grade products. The important thing to remember is that for a hormone to be considered "natural" its structure must replicate exactly the structure of hormones your body produces.

A "synthetic" hormone, on the other hand, may have a structure similar to, but not exactly the same as, a hormone produced by your body. However, these chemical differences can mean that the synthetic hormone acts differently in your body and produces substantially different effects. "Natural" and "synthetic" hormones should not be considered the same or used interchangeably.
