Cosamin DS is a dietary supplement that contains a combination of >glucosamine, chondroitin (Natrol Chondroitin Sulfate, GNC A-Z Chondroitin Sulfate), and manganese. Glucosamine and chondroitin are compounds similar to those found in the joints of healthy people. Some people believe that they may work together to reduce the pain and stiffness of osteoarthritis. Cosamin DS is generally well tolerated with few side effects. In studies, some people reported intestinal gas, tiredness, itching, and heartburn. In theory, glucosamine may lead to increased blood sugar in people with diabetes by reducing the production of insulin in the body or making the body less sensitive to insulin. Check with your doctor before using glucosamine products if you have diabetes. Since glucosamine is derived from the shellfish, people with shellfish allergies should use Cosamin DS cautiously, and only under the supervision of their doctor. Sources: Davis, W.M.
