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.

Serrapeptase (serratiopeptidase) is a proteolytic enzyme originally isolated from the gut of the silkworm (Serratia marcescens). It hydrolyzes non-living tissue including fibrin, blood clots, cysts, and arterial plaque while sparing living tissue. It reduces bradykinin and other pain-mediating amines, provides anti-inflammatory effects by reducing neutrophil infiltration, and thins mucus by cleaving glycoprotein structures. It may also enhance antibiotic penetration into biofilms.
