Calcium D-glucarate is the calcium salt of D-glucaric acid, which is metabolized to D-glucaro-1,4-lactone (the active metabolite). This lactone inhibits beta-glucuronidase, the bacterial enzyme in the gut that deconjugates (cleaves) glucuronide conjugates from Phase II detoxification. By inhibiting beta-glucuronidase, calcium D-glucarate prevents the reabsorption (enterohepatic recirculation) of estrogen, environmental toxins, and carcinogens that were already conjugated for excretion. This effectively enhances the elimination of glucuronidated compounds, including estrogen metabolites, bilirubin, and xenobiotics.

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.
