Glucosamine serves as a substrate for glycosaminoglycan (GAG) and proteoglycan biosynthesis in articular cartilage. It stimulates chondrocyte production of type II collagen and proteoglycans while inhibiting MMP-3 and aggrecanase enzymes that degrade cartilage matrix. Chondroitin sulfate provides osmotic swelling pressure in cartilage (water retention), inhibits complement-mediated inflammation, and downregulates NF-kB and IL-1beta in synoviocytes. Together they exert synergistic chondroprotective and mild anti-inflammatory effects.
