Branched chain amino acids (BCAA) account for 35% of the essential amino acids in muscle proteins. Leucine, Isoleucine and Valine are essential amino acids provided by different dietary proteins. BCAAs can be taken as supplements, particularly recommended before intense training or demanding physical work. Bcaa PRO contains an 8:1:1 ratio of Leucine, Isoleucine and Valine.
