Healthy people do not need to take this supplement. Researchers working with people suffering from a variety of conditions have been using these amounts of SAMe: depression, 1,600 mg per day; osteoarthritis, 800–1,200 mg per day; fibromyalgia, 800 mg per day; liver disorders, 1,200 mg per day; and migraine, 800 mg per day.
SAMe is not abundant in the diet, though its precursor, the amino acidmethionine is plentiful in many protein foods. It is not known whether increasing one’s intake of methionine will increase the body’s production of SAMe. Supplements of SAMe have been available in the U.S. since 1997.
SAMe is normally produced in the liver from the amino acidmethionine which is abundant in most diets. Folic acid and vitamin B12 are necessary for the synthesis of SAMe, and deficiencies of these vitamins results in low concentrations of SAMe in the central nervous system.3 Low blood or central nervous system levels of SAMe have been detected in people with cirrhosis of the liver,4coronary heart disease,5Alzheimer’s disease, and depression.6
