Main Applications

β-Alanine is a non-protein amino acid that acts as the rate-limiting substrate for the synthesis of carnosine in skeletal muscle; by raising intramuscular carnosine levels it enhances the buffering of acidification during high-intensity exercise. This mechanism underlies its established use in sports nutrition products designed to counter lactic acid accumulation, buffer the acidic pH of working muscle and enhance anaerobic endurance.
