What are Branched-Chain Amino Acids?

Branched-chain amino acids (BCAAs) are a group of three amino acids (valine, leucine and isoleucine) that have a molecular structure with a branch.

BCAAs are plentiful in muscle proteins.
BCAAs stimulate muscle growth in the body.
BCAAs provide energy during exercise.

BCAAs are important for exercise.
Recent research shows that BCAAs increase exercise endurance and may reduce muscle soreness.
