What is s-adenosylmethionine (SAMe)?

S-adenosylmethionine (also known as SAMe) is a manmade form of a chemical that occurs naturally in the body.

SAMe has been used in alternative medicine as a likely effective aid in reducing the symptoms of depression, and in treating osteoarthritis.

SAMe is possibly effective in treating liver disease during pregnancy, improving symptoms in people with fibromyalgia, and in treating nerve problems in people with AIDS, or sexual dysfunction in men with depression.

Other uses not proven with research have included treating liver disease, heart disease, schizophrenia, anxiety, tendonitis, chronic back pain, migraine headaches, seizures, premenstrual syndrome, and chronic fatigue syndrome.

SAMe is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

SAMe may also be used for purposes not listed in this product guide.
