ALA is a dithiol compound that functions as a cofactor for mitochondrial alpha-keto acid dehydrogenases (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase). Both ALA and its reduced form DHLA are potent antioxidants capable of regenerating other antioxidants including vitamin C, vitamin E, and glutathione. ALA activates AMPK, improving glucose uptake via GLUT4 translocation, and modulates NF-kB-mediated inflammatory signaling. It chelates redox-active metals (Fe2+, Cu2+).

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.
