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.
Tributyrin is a triglyceride form of butyrate — a short-chain fatty acid critical for colonocyte health. HDAC inhibitor that supports gut barrier integrity, reduces intestinal inflammation, and modulates immune function. Superior absorption compared to sodium butyrate.
