Background

Methylsulfonylmethane, or MSM, is a form of organic sulfur that occurs naturally in a variety of fruits, vegetables, grains, and animals. MSM is a normal oxidation product of dimethyl sulfoxide (DMSO). It arises from a series of reactions that begin on the surface waters of the ocean. MSM is a white, odorless, crystalline substance that is water-soluble and contains 34% element sulfur.

No evidence suggests that MSM is a necessary part of a normal diet. Sulfur is considered an essential mineral, but no dietary requirement has been established for it. MSM as a vital source of dietary sulfur is unsupported by published research. The nutrient is generally well tolerated, but long-term effects of supplementation with MSM have not been examined.

MSM seemed to improve symptoms of allergic rhinitis and osteoarthritis. However, more high quality research using MSM is necessary to define its role in treating these conditions. Although the Arthritis Foundation reports that MSM is used for pain and inflammation, they do not recommend its use due to lack of clinical trials.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Allergic rhinitis : Preliminary study suggests that MSM may reduce symptoms associated with seasonal allergic rhinitis (SAR). However, additional study is needed to confirm these findings.
Grade: C

Osteoarthritis: Preliminary study has used MSM, alone or in combination with glucosamine, in the treatment of osteoarthritis. The combination may provide pain relief and reduction in inflammation. Further studies on MSM and its effects on patients with osteoarthritis are warranted.
Grade: C
