Leucine is an essential amino acid that is considered by many experts to be the most important of the three Branched Chain Amino Acids. Studies have shown that Leucine supplementation can have dramatic effects on muscle building as it slows muscular degradation and is the only dietary amino acid that signals protein synthesis - the process that builds muscles in the body. Also, Leucine is unable to be synthesized in the human body so it must be ingested through food sources and supplementation.

The supplements we have listed on this page are either pure Leucine or have a high concentration of Leucine such as a high ratio e.g. 4:1:1 or something similar.

Benefits of Leucine:
- Signaling Protein Synthesis
- Build Muscle
- Maintain Lean Muscle Mass
- Stimulate Metabolism
- Burn Fat
