Each serving of on instantized BCAA+L- glutamine powder provides a 5000mg (5g) blend of the three branched chain amino acids (L-valine, L-leucineand L- isoleucine) and L- Glutamine in every serving. The branched chain amino acids (BCAAs), so named because of their branched chemical structure are essential in that the body can not make them form other compounds. BCAAs, or branched chain amino acids, have long been used by strength-training and endurace athletes alike to activate muscle synthesis and reduce muscle breakdown caused by intense training.
