Athletes, Body Builders and Active Lifestyles Branched Chain Amino Acids benefit muscle metabolism and provide energy directly to muscle tissue.* The body requires higher amounts of branched chain amino acids during and following exercise as they are taken up directly by the skeletal muscles versus first being metabolized through the liver, like other amino acids. Low BCAA levels contribute to fatigue and they should be replaced in one-hour or less following exercise or participation in a competitive event.
