A Dietary Supplement Vegan. Non-GMO. Endurance. Muscular endurance. Delays muscle fatigue. 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 Sports uses CarnoSyn, 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 Sports 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.
