L-Leucine is essential for growth, stimulates the production of muscle tissue, and protects the liver from the damaging affects of alcohol. L-Leucine is an essential amino acid, which cannot be manufactured in the body and is part of the three branched-chain-amino-acids.
L-Leucine is a branched chain amino acid used as a source of energy. It helps reduce muscle protein breakdown. L-Leucine modulates uptake of neurotransmitter precursors by the brain as well as the release of enkephalins, which inhibit the passage of pain signals into the nervous system. L-Leucine promotes healing of skin and broken bones.

Function:
1. L-Leucine is the forth most concentrated amino acid in skeletal muscle tissue - it comprises about eight percent of the total amino acid count in your body's protein structures. As one of the three BCAA's, Leucine is essential to your basic health.
2.As an amino acid infusion and synthetic amino acid preparation.
3.L-Leucine maintains nitrogen balance, and it has also been shown to enhance thinking abilities that can decline as physical activity becomes more intense L-Leucine also works to heal bone, skin and muscle tissue.
Application:
1.Applied in food field;
2.Applied in medicine field;
3.Applied in health-care products field;
