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.*

Caution: Beta-Alanine may cause a harmless, temporary tingling sensation on the skin for some individuals. After a few weeks of supplementation with Beta-Alanine, this sensation normally lessens or subsides. Licensed under one or more of U.S. Pat.
