New scientific studies show that Leucine is a powerful nutritional activator of muscle protein synthesis. It activates the anabolic pathway for building muscle.
These new findings confirm that within the context of a mixed macronutrient intake, suboptimal protein doses can be made more effective in stimulating myofibrillar protein synthesis, through the addition of a high proportion of free Leucine.
This branched chained amino acid is essential for achieving a positive nitrogen balance in building lean muscle mass.
Leucine is discribed as the trigger of muscle protein synthesis.
