Among the three BCAA amino acids (leucine, isoleucine, valine), leucine plays the most important role in the metabolism of the skeletal muscle and protein and the primary amino acid anticatabolic action. The main job of Leucine is increased protein synthesis and muscle protection from oxidation and catabolism during training. It is important to know that from the very first minute of training the BCAA amino acids are first dissolved and indeed this continues even after the end of the training. Leucine is essentially the amino acid that protects muscles, while the other two BCAA play a supporting role in this process, helping substantially Leucine penetrate the muscles and begin the process of protein synthesis.

The  WARRIORLAB’s L-Leucine, is in free form which is available helps to increase the presence of this very important amino acid in other pre or intra workout supplementation to protect muscles from hard training. The result is better muscle recovery and growth.

WarriorLab's Leucine comes from a 100% plant source and is therefore an ideal source of amino acids for people who follow a vegetarian or vegan way of eating.
