Glycosaminoglycans (GAGs) are important building blocks of connective tissue, including cartilage. GAGs, such as chondroitin sulfate, are necessary to help maintain healthy joint structures.* Glucosamine sulfate stimulates the formation of GAGs and inhibits their degradation.* In this way, glucosamine sulfate supports healthy cartilage formation.* Clinical studies have shown that 6-8 weeks of glucosamine sulfate supplementation promoted healthy joint function and reduced tenderness and swelling.*
