Branched-chain amino acids (BCAA) are an important group of essential amino acids consisting of Leucine, Isoleucine and Valine. BCAA are among the nine essential amino acids for humans, because our body is not able to produce them. The body’s only supply is through daily diet or supplementation. 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 POWDER contains a 2:1:1 ratio of Leucine, Isoleucine and Valine.
