Deliver important oxygen and nutrients to the joints to help remove wastes from the joints; Improves joint metabolism. Enhance joint immune function:

One of the important functions of chondroitin is to act as a conduit for important oxygen supplies and nutrients to the cartilage, while removing carbon dioxide and waste. Since there is no blood supply to the articular cartilage, all oxygenation, nourishment, and lubrication comes from synovial fluid. Loss of chondroitin due to aging, injury, or disease can result in insufficient synovial fluid secretion of articular cartilage, resulting in malnutrition, dryness, thinning, and fragility of cartilage. In addition, cartilage damage caused by injury or daily wear and tear is more difficult to recover or heal without proper nutrition.
