Moderate exercise is also a component in balancing the functions of the body and building bone strength. Diet, exercise, and natural progestorone will almost always correct the imbalance. John R. Lee, MD, the pioneer in the field of progesterone therapy, says that taking natural progesterone lowers the risk of osteoporosis, PMS, fibrocystic breast conditions, ovarian cysts, miscarriage, menopausal symptoms, and breast and endometrial cancer. Evidence that natural progesterone relieves PMS conditions and menopausal symptoms is based on the clinical findings of Lee and other physicians. Evidence that it prevents and even reverses osteoporosis and prevents certain forms of cancer is based on the common scientific understanding that estrogen and progesterone must be in balance to prevent bone loss and certain cancers.
Manufacturers convert diosgenin to the identical progesterone molecule that the body produces.
Therefore, progesterone is natural. It is not a synthetic substance. Progestin is synthetic, because it is not found naturally in the body. Please note that the various creams currently being sold in many health food stores for the treatment of menopausal symptoms, containing Mexican wild yam without natural progesterone, are useless. The diosgenin contained in the yam must first be converted to progesterone, a process that the body cannot do.
