Jarrow Formulas® MSM Sulfur is an organic source of bioavailable sulfur, an antioxidant mineral found in major structural tissues of the body such as cartilage. The sulfur from MSM is used to produce glycosaminoglycans (or mucopolysaccharides) such as chondroitin sulfate, dermatan sulfate, and hyaluronic acid. These sulfur containing glycosaminoglycans are found in high concentrations in connective tissue, including joint cartilage, skin and collagen.*

For best results, use with Jarrow Formulas® BioSil™, the concentrated Biologically Active Silicon™, for stronger, healthier bones, joints and skin.*
