&ampnbsp;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 CarnoSyn&ampreg;, 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&ampreg; Beta-Alanine is backed by scientific research demonstrating that CarnoSyn&ampreg; supplementation results in delayed muscle fatigue and rapid recovery time, thereby helping you attain your strength and endurance training goals.*
