Comprehensive Musculoskeletal Support Joint Support Formula (formerly Arthroplex) helps optimize the normal function of joints and muscles, as well as providing nutrients and botanicals that are necessary for creating collagen, repairing damage, and maintaining a healthy inflammatory response. Key Nutritional Support Features: Provides the proven joint support of chondroitin sulfate, glucosamine sulfate, MSM, hyaluronic acid, and ascorbic acid CurcurVet (R) curcumin phytosome, Boswellia, and bromelain help maintain a normal inflammatory response. DL-Phenylalanine helps dampen the pain response Glucosamine Sulfate, Chondroitin Sulfate, and Hyaluronic Acid Glucosamine and chondroitin are both natural components of cartilage. Numerous animal and human studies have examined the effect of giving these nutrients orally on joint health, and have demonstrated significant clinical benefit. Hyaluronic acid is also a normal component of cartilage and joint structures, and has been shown to be a “chondroprotectant” — a substance that protects cartilage from damage. MSM MSM (methyl sulfonyl methane) provides sulfur compounds for the formation of cartilage. A combination product containing MSM, glucosamine sulfate, and chondroitin sulfate was given to rats with experimentally-induced joint inflammation. The combination provided protection against cartilage damage when given acutely, and better protection when given chronically.
