Leucine is a crucial essential branched-chain amino acid that your body can't make and must be picked up from your diet or supplements. This blend supplies L-leucine, a amino acid used to help with muscle protein synthesis and recovery after workouts. Leucine helps to trigger the mTOR pathway, supporting muscle protein synthesis after training. Dr. Churchward-Venne at Stanford University showed that leucine can stimulate muscle protein synthesis, helping with muscle recovery after training. This mechanism helps keep lean muscle and aids recovery during intense physical activity. *This product isn't meant to diagnose, treat, cure, or prevent any disease.
