Dietary supplement. Branched Chain Amino Acids. 100% Pure pharmaceutical grade. Maximum strength. Maximum absorption. Dymatize BCAA Complex 5050 is a maximum strength formula designed to provide a 5050 mg complex of the purest free form amino acids L-Valine L-Leucine and L-Isoleucine in every serving. These three protein-sparing amino acids are known as branched chain. The branched chain amino acids (BCAAs) 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 BCAAs have been investigated for their potential anticatabolic (preventing muscle breakdown) and anabolic (muscle building) effects. Investigative studies have shown BCAAs are an important component for effective muscle growth muscle energy & recuperation.
