Beta Alanine is a supplement that lends itself well to synthesizing L-Carnosine, a type of amino acid that provides a host of benefits in its own right. This supplement is particular useful to those involved in large amounts of physical activity, such as athletes or bodybuilders. Beta Alanine is chiefly useful in increasing the longevity of endurance when doing any sort of physical activity, allowing the person taking it to exercise much longer and thus increase their muscle mass or burn their fat much more efficiently. In addition, it indirectly helps to widen the blood vessels via L-Carnosine, which increases blood flow during long bouts of exercise.
