BCAA powder, or energy powder, contains essential amino acids, which are referred to as branched chain amino acids because they have a chemical structure which separates them from the rest of the essential amino acid family. BCAA's make up 40% of total body protein content and represent around 15 to 25 percent of total protein intake overall. BCAAs are found in their greatest natural quantities in products such as red meat and many types of dairy. This BCAA powder is at a ratio of 3:1:2 of leucine, isoleucine, and valine and is derived from corn. Leucine is the product of protein hydrolysis by way of various enzymes present in the pancreas. This reaction is part of the overall digestive process. Isoleucine may help stimulate the production and circulation of energy throughout the body.* Valine is essential in maintaining the structure of various proteins into which it has been incorporated. BCAA powder is commonly taken by athletes and body builders as muscle-building and endurance supplements.
