Product feature

Branched chain amino acids (BCAAs for short) consist of the essential amino acids leucine, valine, and isoleucine. They are the building blocks of protein and muscle. The body can't make these amino acids on its own, that is why dietary supplementation is essential. 
Youth Bio BCAAs with a higher leucine content stimulate protein synthesis more effectively--which is why this powder has an optimal 2:1:1 ratio of leucine, isoleucine, and valine to maximize its benefits. 
Used before endurance training, the Branched Chain Amino Acids (BCAAs) leucine, isoleucine and valine can help spare muscle. 
Used after strength training, they help kick-start protein synthesis which plays an important role in muscle building.
