The branched-chain amino acids (BCAAs), leucine, isoleucine and valine are essential amino acids, and thus
cannot be made in the body. BCAAs are critical for muscle protein synthesis, and because BCAAs can be used
as fuel during intense exercise, BCAA supplementation can help to preserve existing muscle tissue. In addition,
BCAAs can support the recovery process by promoting the normal repair processes that take place after
exertion. BCAAs also play an important role in the maintenance of proper immune system function
and the support of healthy aging. NOW Branched-Chain Amino Acids are pharmaceutical grade.
