Methylsulfonylmethane
Uses
Methylsulfonylmethane (MSM) is a naturally occurring, organic, sulfur-containing compound related to another sulfur-containing substance, dimethyl sulfoxide (DMSO). MSM is found in small amounts throughout nature and has been detected in small amounts in the blood and urine of humans.1
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
| Used for | Why |
|---|---|
2 Stars Osteoarthritis 2.25 to 6.0 grams per day | In one trial, supplementing with methyl-sulfonylmethane significantly reduced pain and improved overall physical functioning in patients with osteoarthritis of the knee. According to a small double-blind trial, 2,250 mg per day of oral (MSM), a variant of DMSO, reduced osteoarthritis pain after six weeks. In another double-blind trial, supplementation with 3 grams of MSM twice a day for 12 weeks significantly reduced pain and improved overall physical functioning in patients with osteoarthritis of the knee. |
How to Use It
Some authorities report anecdotally that 250–500 mg per day has beneficial effects on a variety of health problems.2 However, the only controlled trial using MSM used over 2000 mg per day to treat osteoarthritis. More research is needed before reliable recommendations for MSM supplementation can be made.
Where to Find It
A precursor of MSM is formed initially by ocean plankton and released into the atmosphere, where it interacts with ozone and sunlight and returns to earth as MSM in rainfall. MSM can be taken up by plants and incorporated into their structure, but no measurement of the MSM content of foods has been done. Supplements containing MSM are available.
Possible Deficiencies
Although MSM is present in food, it is not an essential nutrient, so deficiency is not likely.

Side Effects
According to some anecdotal reports, MSM has been used in human research for many years in amounts above 2000 mg per day with no significant adverse effects.3 However, diarrhea, skin rash, headache, and fatigue may be experienced in less than 20% of people, according to other anecdotal reports. Detectable levels of MSM in the brain of a person taking MSM supplements have been reported,4 but the significance of this finding, if any, is unclear.
