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.

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.
