Connective tissue that make up the spinal discs, ligaments, cartilage & tendons between the joints are constantly being repaired & renewed to keep them in optimum condition. The body does this by complex chemical processes using substances such as collagen & glucosaminoglycines. Glucosamine is one of the active constituents that help to make up the glucosaminoglycines. Consequently the rate of repair of tissue damage to the body is governed by the rate of formation of glucosaminoglycines. Glucosamine Sulphate from Health Aid is specially formulated with vitamin C & calcium to help increase the rate of absorption, assimilation & benefit.
