Glucosamine is a building block of cartilage and joint tissue Chondroitin is the tough connective tissue within joints MSM is a natural form of organic sulphur one of the major building blocks of glycosaminoglycans (key components of cartilage) These tablets contain a high strength blend of Glucosamine and Chondroitin with MSM. Glucosamine and Chondroitin are naturally found in the joints of the body. Rarely found in natural food sources, Glucosamine is a building block of cartilage and joint tissue. It is the basis of the synthesis of several important macromolecules including glycoproteins, glycolipids and glycosaminoglycans. These macromolecules can be found in the synovial fluid, cartilage, tendons, ligaments and muscles.
