Patient Education

Methylsulfonylmethane (MSM)


What is it? Methylsulfonylmethane (MSM) is a chemical found in green plants, animals, and humans. It can also be made in a laboratory.

Some literature that promotes MSM states that MSM can treat sulfur deficiency. But there is no Recommended Dietary Allowance (RDA) for MSM or sulfur, and sulfur deficiency has not been described in the medical literature.

People use MSM for osteoarthritis. It is also used for pain, swelling, aging skin, and many other conditions, but there is no good scientific evidence to support most of these uses.
