What are BCAAs?

BCAA is the acronym for Branched-Chain Amino Acids and refers to three amino acids with a "branched-chain" chemical structure: leucine, valine, and isoleucine. They are all essential amino acids, which means the body cannot synthesise them and they must be obtained through diet or food supplements.

Scientific studies report that BCAAs:

  • Are essential for protein synthesis in humans
  • Support muscle growth and recovery
  • Contribute to energy metabolism during exercise
