Product Overview
MSM (Methylsulfonylmethane, dimethyl sulfone) is a naturally occurring organic sulfur compound found in fruits, vegetables, grains, and human tissues. With CAS number 67-71-0 and molecular formula C₂H₆O₂S, MSM is a popular ingredient in joint health, sports nutrition, and beauty-from-within formulations. It is also available as a United States Pharmacopeia (USP) reference standard, indicating pharma-grade quality verification is well established.
Published research suggests MSM may support joint comfort, exercise recovery, and healthy inflammatory response. It is commonly paired with Glucosamine and Chondroitin Sulfate in complete joint health formulas, and is also used in standalone formulations targeting active adults and athletes.
