Glucosamine is used by the body to make other chemicals that build tendons, ligaments, cartilage, and the fluid that surrounds joints. Joints are cushioned by the fluid and cartilage around them. Taking glucosamine might increase the cartilage and fluid around joints and/or help prevent their breakdown.

 Glucosamine and chondroitin protect cells called chondrocytes, which help maintain cartilage structure. In theory, these supplements have the potential to slow cartilage deterioration in the joints, and to reduce pain in the process.

 Laboratory studies have found that MSM has anti-inflammatory and antioxidant effects. Sulphur, which is a major component of MSM, plays an important role in making collagen and glucosamine, both of which are vital for healthy bones and joints, and in the production of immunoglobulins, which help your immune system.
