A naturally occurring sulfur-containing chemical that is taken as a dietary supplement. Some people take MSM for arthritis, but there is little medical evidence showing its benefits.
Methyl Sulfonyl Methane (MSM) is an organic sulfur compound found in small amounts in foods and beverages. It is widely used in the treatment of arthritis, but has also been used to treat gastric conditions, seasonal allergies, and snoring. Comments: While clinical trials of MSM showed no serious side effects, research does not exist concerning long-term effects on humans.
MSM, also called "organic sulfur," is widely used around the world for relief of pain from arthritis, back pain or muscle pain. MSM is a close relative of DMSO.
