Women use pregnenolone for lumpy breasts (fibrocystic breast disease), a disorder of the lining of the uterus (endometriosis), symptoms of menopause, andpremenstrual syndrome (PMS).
Some people use pregnenolone for slowing or reversing aging, arthritis, anddepression. It is also used for strengthening the heart, allergic reactions, “detoxification,” lupus, multiple sclerosis (MS), prostate problems, and seizures.
