AKG is a TCA cycle intermediate that declines with age. Supplementation reduces inflammatory cytokines, improves stem cell function, and extends healthspan in mice. Calcium salt form provides sustained release. Also supports collagen synthesis and reduces frailty markers.
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.
