Beta-alanine
Overview	Beta-alanine augments intracellular buffering capacity, having potential beneficial effects on sustained high-intensity exercise performance.
Mechanism	A rate-limiting precursor to the endogenous intracellular (muscle) buffer, carnosine; the immediate defence against proton accumulation in the contracting musculature during exercise81 Chronic, daily supplementation of Beta-alanine increases skeletal muscle carnosine content.82
