Not many people realize how important a role progesterone plays in overall good health. See the whole article for specific lists of benefits.
“Progesterone is a steroid hormone made by a woman’s ovaries when she ovulates and in smaller amounts by the adrenal gland. A menstruating woman will typically produce about 20 to 30 mg of progesterone a day during the luteal or last phase of her menstrual cycle.
While menopause doesn’t typically occur until age 50 or later, many women can start going out of balance in their 30s or even earlier. This decline in progesterone is not trivial for as women age into their fourth, fifth, and sixth decade, their progesterone levels continue to fall. By the time they reach perimenopause as much as 75% or more of their youthful progesterone secretion may already be missing.
Natural progesterone is very useful to balance excess estrogen which can be a major risk for breast cancer. Natural progesterone is also different from estrogen in that your body can use it as a precursor or starting material to make other hormones such as adrenal hormones. It can even convert it into estrogen or testosterone if your body needs it.
Natural progesterone is made from a substance called diosgenin which is commonly extracted from wild yams or soybeans. Even though it may be extracted from soy it is a highly purified hormone and there are absolutely no remnants of soy substances that would lead to any problem.” Dr. Joseph Mercola
