| Progesterone is also produced by the ovaries and compliments estrogen. Soy products contain phytoestrogens that act by altering tissue responses to estrogen. Dr. John Lee, a medical practitioner, independent researcher and author, has for 15 years conducted independent research into a natural, plant-derived form of progesterone. Millions of women in the Western world now use natural progesterone - generally in the form of a cream which is rubbed into the body. Considering that it is non-patentable and inexpensive, it is not surprising that this is so. There is a big difference between the two in their effect on the body, although doctors most often use their names interchangeably. Since natural progesterone is not a patentable product, the pharmaceutical companies have altered it to produce synthetic progestins commonly used in contraceptives and HRT. A partial list includes headaches, depression, fluid retention, increased risk of birth defects and early abortion, liver dysfunction, breast tenderness, breakthrough bleeding, acne, hirsutism (hair growth), insomnia, edema, weight changes, pulmonary embolism and premenstrual-like syndrome. [Lee, John R., M.D., Slowing the Aging Process with Natural Progesterone, BLL Publishing, California, USA, 1994, p.12.]. Progesterone is an essential hormone that also plays a part in the development of healthy nerve cells and brain and thyroid function. Prometrium® is available in a 100 and 200mg capsule. Natural Progesterone has been used for the treatment of arthritis, tendonitis, bursitis and varicose veins. Some of the progesterone will be absorbed systemically, but the highest concentration is sustained in the local area, helping to correct the problem. Directions Hormone levels may need to be tested prior to hormone cream use. Your doctor should know whether testing is necessary or not. Your doctor may prescribe doses of up to 100mg or more. A reputable researcher, Ray Peat, Ph.D. claims that progesterone dissolved in Vitamin E is far better absorbed than other types/forms. Progesterone used vaginally targets the uterus and is absorbed systemically as well. Side-Effects Natural progesterone is not known to have any toxic levels to date. |
