BCAA 6000 from Gaspari Nutrition uses a leucine heavy, 4:1:1 ratio of 100% pure pharmaceutical grade branched chain amino acids in a formula that provides clinically validated and effective quantities of these critical nutrients in every dose. The branched chain amino acids (BCAAs) got their names due to their unique molecular structure that are different from the other amino acids. All BCAAs are considered essential amino acids because your body can't synthesize them from other compounds and they must be obtained through your diet. Bodybuilders and other high level, advanced athletes have known for years that the BCAAs are responsible for helping to increase protein synthesis which can lead to faster recovery time, increased lean muscle mass and increased performance and endurance all around. The addition of advanced, highly bio-available forms of Vitamin B-6 and Vitamin B-12 to the BCAA 6000 complex will also help to enhance your energy levels and endurance helping to further maximize your training while simultaneously enhancing recovery. What Does BCAA 6000 Do? BCAA helps to enhance post exercise muscle recovery, helps to increase protein synthesis in lean muscle, helps to decrease muscle soreness after exercise, rapidly augments energy synthesis with the aid of clinically validated amounts of vitamin B-6 and B-12 and helps to optimize aerobic and anaerobic sports performance.
