Nutrabay Gold BCAA 2:1:1 with Electrolytes is a premium blend of BCAA having a high ratio of L-Leucine. Branched-chain amino acids are components of protein that maintain muscle tissue during intense exercise. They function as anabolic agents, which allow the body to maximize fat loss and minimize muscle loss. They are rapidly depleted from the muscles when training. Taking them pre-workout and/or during your session can delay fatigue. Taking them post-workout, or with a post-workout meal, will lower muscle damage and feed the muscles faster to keep you in an anabolic state.
