Product Information: Joint wear occurs when articular cartilage wears out faster than it is produced The body is prompted to protect articular cartilage from further damage by producing more healthy cartilage. Chondroitin is a building block of cartilage. Chondroitin and glucosamine are part of the jelly-like substance that gives cartilage viscosity and resilience. They determine the quality of the synovial fluid, which improves metabolism in the joint. Both glucosamine and chondroitin can be absorbed through the intestinal system to reach the joints. There are no known adverse side effects of either product.
