Active metabolite of berberine with 5x greater absorption. AMPK activator that improves insulin sensitivity, reduces hepatic glucose production, and modulates gut microbiome. More bioavailable form allows lower dosing with fewer GI side effects.
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.
