BCAA 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. BCAAs 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 2:1:1 of leucine, isoleucine, and valine and is derived from corn. These are the three amino acids that are considered BCAA: Leucine, Isoleucine, and Valine. First, Leucine is the product of protein hydrolysis by way of various enzymes present in the pancreas. Second, Isoleucine helps stimulate the production and circulation of energy throughout the body.* And lastly, Valine is essential in maintaining the structure of various proteins that it has been incorporated into the body. BCAA is commonly taken by athletes and body builders as muscle-building and endurance supplements. BCAA powder may work with protein to help build strength, assist with muscle recovery after strenuous workouts, and promote muscle endurance.* Lastly, it may also help support good blood sugar levels in individuals, maintain weight in conjunction with diet and exercise, and support the liver.* This is the powder form.
