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.
