Why Progesterone? Isn't Mexican Wild Yam enough ?
A component of Yam (diosgenin) was, at one time, thought to be converted in the body to progesterone but that has been proven to be unsubstantiated. In fact, while it has certain health benefits, there are no published studies that would allow one to conclude that Yam will increase progesterone levels in humans or animals. Only supplemental Natural Progesterone has been demonstrated to increase serum and saliva progesterone levels in women, a fact that is verified by ample clinical and published scientific research.
