About this ingredient
MSM (Methylsulfonylmethane) is an organic sulfur compound also known as dimethyl sulfone. It is widely used as a nutritional supplement ingredient and is frequently included in joint-support and mobility formulas.
MSM has been studied in connection with osteoarthritis and joint symptoms, but authoritative reviews note that there is currently insufficient evidence to determine whether MSM provides meaningful benefits for osteoarthritis.
Because MSM contains sulfur, it is sometimes included in nutritional formulas focused on connective-tissue and general wellness support. It is also used in combination formulas containing glucosamine, chondroitin, collagen, or other nutritional ingredients.
