Branched-Chain Amino Acids are building blocks of protein, which you already know is essential for body mass development. It fuels the body, while repairing muscles for better recovery.
BCAAs are taken up by the muscle directly instead of being metabolized in the liver and are an excellent buffer against catabolism if you're fasting before exercising. They have a fatigue reducing effect because it limits entry of tryptophan to the brain.
Our BCAAs are 2:1:1 (leucine, isoleucine, valine) ratio because leucine is one of the most essential amino acids for stimulating protein synthesis and suppressing breakdown of muscle protein.
