Amino Acid Supplements
BCAA (branched-chain amino acid) supplements contain valine, leucine and isoleucine. These are considered ‘essential’ amino acids because they need to be present in your diet - as opposed to ‘non-essential’ amino acids, which your body can produce itself. Together, they can comprise up to one-third of muscle protein.They can help prevent the breakdown of muscle tissue during intense exercise. They also increase the release of human growth hormone.
