* Virtually all progesterone cream is derived either from soy or wild yam. There are some studies that show wild yam has in the past few years been found to be the best source of natural progesterone cream. This is not to say that plain Wild Yam Cream is a source of progesterone - there is a difference. That means that, like soy, wild yam has been synthesized into progesterone cream - soy is not progesterone, either. Creams derived from either are okay to use. |
