As far as I can tell, "Bioidentical" is a trick word for "synthetic." It's not natural. Here's the thing: pharmaceutical companies are trying really really hard to find a way to make a profit selling progesterone. They can't do it. Natural progesterone is safe, it's inexpensive and they can't make a profit so they're trying to find ways to convince women to buy this stuff. I've been using nautral progesterone cream for several years. It has cured my fibroids, and a couple of ovarian cysts! I buy it from Arbonne.

It's hard to "do your homework" when there are so many slick sales people out there, especially these companies that come up with crazy terms like "bioidentical" and try to convince us that this is the same as natural. I wouldn't mess with it. Megan -- are you a pharmaceutical rep or something?
