Glucosamine sulfate and MSM provide intrinsic compounds essential for healthy cartilage formation, including glycosaminoglycans and elemental sulfur, respectively. MSM has also been attributed with enhancing healthy immune cell activity, thereby supporting tissues surrounding the joints. These important cartilage matrix constituents are complemented with additional factors for supporting a healthy immune response. In studies, ginger promotes healthy prostaglandin and leukotriene biosynthesis. Curcumin helps maintain healthy neutrophil function and scavenges free radicals.‡
