Beta-alanine is a non-essential amino acid that is used by muscle cells to synthesize carnosine. Carnosine is a dipeptide (beta-alanine plus histidine) that functions as a buffer for the hydrogen ions (acid) produced during strenuous exercise thus helping to maintain optimum muscular ph. Now uses carynosyn a patented form of beta-alanine that has been clinically tested and shown to increase muscle carnosine content allowing muscles to work harder and longer during intense exercise. Now beta-alanine is backed by scientific research demonstrating that carnosyn supplementation results in delayed muscle fatigue and rapid recovery time thereby helping you attain your strength and endurance training goals.
