Methylsulfonylmethane (MSM), is an organosulfur compound with the formula (CH3)2SO2. Methyl sulfonyl methane is also known by several other names: DMSO2, MSM, methylsulfonylmethane and methyl sulfone. This colourless solid features the sulfone functional group and is considered relatively inert chemically. Methyl sulfonyl methane occurs naturally in some primitive plants and is present in small amounts in many foods and beverages and Methyl sulfonyl methane is marketed as a dietary supplement, although its benefits are disputed.
MSM is promoted as a natural source of sulfur by the supplement and health food industry, suggesting that people are deficient in sulfur intake. However, protein in the diet is an abundant source of sulfur, which is contained in the amino acids methionine and cysteine. There is no Dietary Reference Intake (DRI) or Daily Value established for sulfur. MSM is sold as a dietary supplement that is marketed with a variety of claims and is commonly used (often in combination with glucosamine and/or chondroitin) for helping to treat or prevent osteoarthritis. The biochemical effects of supplemental methylsulfonylmethane are poorly understood. Some researchers have suggested that MSM has anti-inflammatory effects. Any health effects of dimethyl sulfoxide (DMSO) may be mediated, at least in part, by MSM. Stanley W. Jacob, M.D., of the Oregon Health and Science University, reports using MSM to treat over 18,000 patients with a variety of ailments - no link to this at OHSU website per OHSU search engine. The health claims made on using MSM exceed the number of scientific studies available to strongly support its effectiveness.
