There s no cure for osteoarthritis, but patients can take steps to control the symptoms. When pain or disability are severe, doctors may recommend surgery or joint replacement. Glucosamine is naturally found in almost all body tissue. It helps maintain and repair joint cartilage. Chondroitin is a component of cartilage tissue.
Researchers believe it inhibits the action of enzymes that cause cartilage breakdown.
The supplements are synthetic versions of the natural substances. The benefits of glucosamine and chondroitin supplements haven t been scientifically proven. Several small studies suggest glucosamine and chondroitin may help reduce joint pain in patients with osteoarthritis. Other studies have found no positive effects. Researchers are more concerned about the long-term safety of glucosamine and chondroitin.
