L-Leucine is an essential amino acid that is part of the branched chain amino acids (bcaa’s). Because it is not synthesized in humans, Leucine must be ingested through diet and supplementation.L-Leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins. L-Leucine has several health benefits including preservation of muscle glycogen and lean muscle tissue and enhanced protein synthesis. Both of these are vital to lean mass growth.
