Chondroitin sulfate supplements are intended to enhance the shock-absorbing properties of collagen and prevent the further breakdown of cartilage. They do so by increasing water retention in cartilage cells and, when used with glucosamine, may even help reverse cartilageloss.
Glucosamine is believed to help slow deterioration of cartilage, relieve arthritis joint pain, and improve joint mobility. Chondroitin is also found naturally in cartilage and bone. Chrondroitin sulfate supplements are derived from cow trachea or pork byproducts.
