Branched chain amino acids (BCAAs) are three essential amino acids: leucine, isoleucine and valine. Since our body cannot synthesize them, we must provide them through our diet. Branched chain amino acids play a major role in muscle recovery processes and interact directly in protein synthesis. There is research that states that BCAAs not only stimulate muscle growth, but also provide energy to muscle tissue, promote fat burning and accelerate the muscle recovery process. Instructions for use: Take 2 capsules before physical activity and 2 after.
