What are branched-chain amino acids (BCAAs)?

ANSWER

Branched-chain amino acids are essential nutrients -- they're proteins found in food. Your muscles "burn" these amino acids for energy.

The specific amino acids that make up the branched-chain amino acids are leucine, isoleucine, and valine. The term "branched-chain" refers to their chemical structure.
