Bestvite's synergistic Glucosamine/Chondroitin/MSM formula combines three of the most effective nutrients for supporting joint health. Our Glucosamine and Chondroitin are both in the prefered sulfate form. Glucosamine is an amino sugar derived from the shells of shellfish that provides the building blocks for supporting cartilage and flexibility of the joints. The MSM (methylsulphonylmethane) is an organic form of sulfur found in all living organisms. MSM provides the chemical links needed to form and maintain various tissues such as connective tissues and articular cartilages found in the body. Glucosamine, Chondroitin and MSM work synergistically to provide optimal joint support.*
