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 3:1:2 of leucine, isoleucine, and valine and is derived from corn. BCAA powder 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.* BCAA powder may also help support healthy blood sugar levels in already healthy individuals, maintain healthy weight in conjunction with a healthy diet and exercise, and support the liver.** These statements have not been evaluated by the Food and Drug Administration.
