Methylsulfonylmethane
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.
How to Use It
Some authorities report anecdotally that 250–500 mg per day has beneficial effects on a variety of health problems.4 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.
