Glucosamine and chondroitin sulfate are components of normal cartilage. In the body, they are the building blocks for cartilage and appear to stimulate the body to make more cartilage.

There are conflicting studies on glucosamine and chondroitin, some demonstrating a beneficial effect on osteoarthritis pain. Others, including the NIH-sponsored multicenter Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), did not show benefit for the primary outcome of reducing pain.
