BCAAs are vital to muscle protein synthesis, which is your bodys process for building new muscle. Muscle BCAA supplements amino acids to support healthy protein synthesis, helping you to make gains in muscle and tone. Go Harder, Longer. Exercising releases serotonin, which can make you feel drowsy during long workouts. BCAAs may help to lower serotonin levels during endurance sports and workouts, helping you work harder for longer and recover faster than ever before. Optimal 2:1:1 Ratio. We formulated Muscle BCAA to include the 2:1:1 ratio of essential amino acids: L- leucine, L-isoleucine, and L-valine. This optimal ratio, along with a 2500 mg dosage, is a vital part of any supplement stack for active men and women. What Sets Us Apart?
