Good joint health begins with keeping active and working the joints. Supplements can help joint health by providing the nutrients that are required for maintenance and good function. Calcium and Vitamin D are both suggested as they keep the underlying bone structures healthy. Omega-3s are good as they can help reduce inflammation in the joints. Glucosamine and Chondroitin are key components of cartilage, the material that forms the joints, and a good supply can help with maintenance.
