There is an enormous amount of research on bioidentical hormones, one just needs to know about the research or READ the research.

The term "bioidentical" usually (but not medically) refers to the molecular structure of a hormone—this is not the same as the term "natural." For example, Premarin®, which comes from pregnant mare’s urine, could be considered "natural," however, it is not structurally identical to human estrogen (although it would be bioidentical if you were a pregnant horse!) The same is true for Provera®, a synthetic progestin that has been shown to have significant detrimental health effects. When the term bioidentical hormone replacement therapy or BHRT is used it usually refers to human-identical hormones.

You are probably wondering why do we use the word, "bioidentical"? That's an excellent question. I can remember back when I was in first year medical school learning biochemistry at the University of Illinois in Chicago. Our class used Lehninger's classic textbook of biochemistry. Lehninger never used the word, bio-identical hormones, because all hormones are by definition, bioidentical hormones. They simply used the word, "hormone". Using a word like "bioidentical" was simply redundant and unnecessary for a biochemistry textbook, as it should be today.

Why are the smart women switching to bioidentical hormones?
Bioidentical hormones are safer and more effective than chemically altered synthetic hormones.

Not enough research has been done to determine the side effects of bioidentical hormones. While the purity, potency, efficacy or safety hasn't been necessarily proven or tested by the FDA, some women appear to really prefer them. For example, earlier this year, a Tucson pharmacy was warned by the FDA to stop producing bioidentical hormones. However, a Tucson representative, at the urging of nearly 150 women, protested the demand.

Here's an article from Harvard that explains bioidentical hormones more.
