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.
Redox cofactor that stimulates mitochondrial biogenesis via PGC-1alpha activation. Potent antioxidant (5000x more efficient than vitamin C in redox cycling). Supports nerve growth factor (NGF) synthesis and protects neurons from oxidative damage.
