NOW® Sports Branched-Chain Amino Acid Powder delivers L-leucine, L-isoleucine and L-valine to promote muscle strength and recovery.
Of the eight essential amino acids that cannot be produced by the body, the three branched-chain aminos leucine, isoleucine and valine are of key importance. Based on their unique structure, activity, storage and metabolism, BCAAs have become a staple in the lives of many athletes and physically active individuals. They account for nearly 1/3 of the amino acids in muscle protein and play a number of key roles in the growth of muscle tissues.
