Scientifically formulated Nutra-Life Joint Formula + MSM powder combines MSM with Glucosamine sulfate and Chondroitin sulfate, both of which may support the health and function of joints. Also included are important supporting nutrients – Copper and Manganese that may help maintain connective tissue. Glucosamine is produced naturally in the body where it may be important for maintaining the elasticity, strength and resilience of cartilage in joints. Glucosamine is also a key building block for cartilage, tendons, ligaments and synovial fluid while Chondroitin may support the health and function of the joints. MSM is a source of sulfur. Cartilage has a high content of sulfur and may be required for the formation of connective tissue.
