Flavonoid (found in chamomile, parsley) that inhibits CD38, the primary NAD+-consuming enzyme. Also a potent aromatase inhibitor and anxiolytic via GABA-A modulation. Supports NAD+ levels, reduces estrogen conversion, and improves sleep quality.
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.
