Dymatize BCAA Complex 5050 is a maximum strength formula designed to provide a 5,050 mg complex of the pure free form amino acids L-Valine, L-Leuceine and L-Isoleucine in every serving. These three protein-sparing amino acids are known as the branched chain. The Branched Chain Amino Acids (BCAA's) got their name because of their unique branched chemical structure. All Branched Chain Amino Acids are essential amino acids, defined as, the body cannot make them from other compounds, they must be consumed in the diet. it is a well known fact that amino acids are responsible for protein synthesis, hence the nickname "building blocks." In recent times, these BCAA's have been investigated for their potential anitcatabolic (preventing muscle breakdown) and muscle building effects. Investigative studies have show BCAA's are an important component for effective muscle growth, muscle energy and recuperation.
