Methylsulfonylmethane (MSM)

Methylsulfonylmethane (MSM), is an organosulphur compound. It is a naturally occurring nutrient, a beneficial form of the mineral sulphur, found in nearly all living organisms, plant, animal and human, with the formula (CH3)2SO2. MSM is sold as a dietary supplement and is commonly used (often in combination with glucosamine and/or chondroitin) for helping to treat or prevent osteoarthritis. There is some clinical evidence for the usefulness of MSM in osteoarthritis but further studies are needed.
