Like Glucosamine and Chondroitin, MSM (Methylsulfonylmethane), may provide raw materials the body needs in order to make cartilage in the first place. MSM is a pure, organic, non-toxic, non-metallic element that occurs widely in nature. It's a metabolite of the compound dimethysulfoxide, and by weight is 34% elemental sulfur, making it one of the richest sources of sulfur. As the eighth most abundant element in all living organisms, sulfur is found in more than 150 types of bodily compounds, from enzymes and tissues to hormones and antioxidants. It's also a component of structural protein, the type found in hair, skin, and joints. Sulfur also occurs in connective tissue, in a key structural component called collagen. (Collagen helps form cartilage).
Researchers predict that MSM will soon be proven effective not only in the treatment of various types of arthritis (including rheumatoid and osteoarthritis), but also in other conditions that involve connective tissue degeneration. (8)
Side effects: No side effects have been reported with the use of sulfur.
Recommended dosage: 1-2 grams per day.
