Increases nitrogen retention and supports protein synthesis to build lean muscle mass and strength.* Prevents muscle tissue breakdown leading to faster recovery and reduced post-workout stiffness.* Scientifically-formulated with a specific ratio of essential amino acids to enhance absorption and muscle tissue recovery.* How It Works: Twinlab BCAA Fuel Powder is available in delicious Fruit Punch flavored, easy-mix powder. It is a powerful combination of precision-engineered branched chain amino acids (BCAAs): L-leucine, L-isoleucine and L-valine. These essential amino acids cannot be made by the body and are rapidly oxidized during exercises so supplemental BCAAs can play a key role in muscle growth and recovery.* * These statements have not been evaluated by the Food and Drug Administration.
