BCAAs, that is, Valine, Isoleucine and Leucine, are Essential Amino Acids, necessary for the proper functioning of the body. Together, they represent around 35–40% of all essential amino acids present in your body and 14–18% of those found in your muscles. However, our body is not able to synthesize them through other compounds, so they must be consumed, usually through food or supplements.
Athletes take Branched Chain Amino Acids seeking to take advantage of their benefits in sports practice. BCAAs are related to its main function of protein synthesis: it is consumed frequently in all sports, since it helps synthesize and recover muscle tissues.
BCAAs can help you ensure optimal and strong athletic performance, regenerate exercised muscle mass, speed post-exercise recovery, and prevent muscles from catabolizing (deteriorating). The ideal and most common use is to take it during training to significantly improve endurance and stamina.
