SAM-e By Nature's Sunshine Overview & Drug Interactions

S-adenosyl-l-methionine (SAM-e or SAMe) is a compound that is found naturally in the body and is involved in various processes, including the synthesis of neurotransmitters and the metabolism of hormones. SAM-e has been studied as a potential treatment for a variety of health conditions, including depression, osteoarthritis, and liver disease. As a dietary supplement, it is most often used for improving symptoms of depression and for osteoarthritis. In regard to depression, research suggests that SAM-e may be more effective than placebo in reducing the severity of depression and may be as effective as certain antidepressants for some individuals. However, more research is needed. Similarly, for osteoarthritis, some studies show that it is as effective in reducing symptoms for some individuals as NSAIDs (e.g., ibuprofen). There are a variety of different forms of SAM-e supplements available on the market, typically different salt forms (e.g., sulfate, sulfate-p-toluenesulfonate, and butanedisulfonate), which may affect how well it is absorbed.
