The Active Ingredient Is: L-Leucine

L-Leucine is an essential amino acid that participates in protein synthesis and plays a key role in muscle metabolism. This formula presents L-Leucine as the primary active ingredient within a complete essential amino acid profile.

It comes from protein sources and is included in the blend to support amino acid availability and overall nutrient utilisation during and after exercise.

What Does L-Leucine Do?

L-Leucine assists with initiating muscle protein synthesis as part of the essential amino acid group. Scientific research suggests that EAAs, including leucine, stimulate muscle protein synthesis and support recovery following strenuous activity.

In the context of normal physiology, leucine contributes to the body’s use of amino acids for tissue maintenance and repair, aligned with EFSA-endorsed understanding of amino acid function.
