Beta Alanine is an amino acid that is necessary for the formation of a molecule called carnosine, which acts as an intracellular buffer. When you exercise, acid accumulates in the muscles, which is a big contributor to fatigue and discomfort. Buffers, like carnosine, help neutralise some of this acid buildup, allowing you to keep exercising for longer. Of course, the more you train, the better the results. Athletes of all types, strength and endurance, have benefited from Beta Alanine supplementation. APS Beta Alanine contains nothing but the pure, CarnoSyn Beta Alanine, which is the best quality product money can buy.
