When it comes to sport nutrition, one of the most effective and beneficial supplements are the branched chain amino acids. For those taking supplements to aid in strength training, BCAA supplements are a good option. BCAA refers to the branched chain amino acids, which include leucine, isoleucine and valine - three of the amino acids your body cannot produce on its own. Leucine, isoleucine, and valine make up around 35% of the skeletal muscle in the body and are necessary for muscle formation, as well as being useful in slowing muscle degradation BCAA's have been investigated for their potential anitcatabolic (preventing muscle breakdown) and anabolic (muscle building) effects. Investigative studies have show BCAA's are an important component for effective muscle growth, muscle energy and recuperation. Available in many forms: caps, unflavoured & flavoured powder.
