Branched Chain Amino Acids (BCAAs) are an important group of essential amino acids made up of Leucine, Isoleucine and Valine. BCAAs are among the nine essential amino acids for humans, because our body is unable to produce them. The only sources of supply are through daily nutrition or dietary supplementation. Branched-chain amino acids (BCAAs) account for 35% of the essential amino acids in muscle proteins. Leucine, Isoleucine and Valine are indispensable amino acids supplied by different dietary protein intakes.

BCAAs can be consumed as supplements, especially recommended after intense workouts or demanding physical work. BCAA 4:1:1 contains a 4:1:1 ratio of Leucine, Isoleucine and Valine.
