Methylsulfonylmethane (Dimethylsulfone or, more commonly, MSM) is a small DMSO-related sulfur-containing molecule used for its antioxidative and anti-inflammatory properties. It holds potential for joint health (not significantly different than glucosamine sulfate).

MSM is most often used for

What else is MSM known as?
Note that MSM is also known as:
  • MSM
  • Dimethyl Sulfone
  • Dimethylsulfone
  • Methylsulfonylmethane
MSM should not be confused with:
  • DMSO (reduced form of MSM)
Dosage information

Supplementation of MSM tends to be taken at up to 3,000mg daily, which seems to be effective for reducing symptoms of osteoarthritis and conferring some antioxidant protection to the body. It is unsure if higher supplemental doses are better than 3,000mg, so sticking to that dose may be prudent.
