All About BCAAs
What are branched chain amino acids?
Amino acids are the building blocks of protein. Branched chain amino acids (BCAAs) are so called because of their structure, which includes a “side chain” of one carbon atom and three hydrogen atoms. There are three BCAAs: leucine, isoleucine, and valine. Of these, leucine is the most heavily researched, and appears to offer the biggest physiological benefit. (More on that below.)
