The Active Ingredient Is: Leucine (Branched-Chain Amino Acid)

Leucine is an essential amino acid that plays a role in muscle protein synthesis and recovery during and after exercise. This formula centers on Leucine as the primary active ingredient, with Isoleucine and Valine providing additional support as part of the BCAA blend.

This combination leverages the primary role of Leucine while including the complementary BCAAs to support the overall amino acid supply for muscle function.

What Does Leucine Do?

Leucine helps support normal muscle protein synthesis, a natural body process involved in muscle maintenance and growth during training. EFSA acknowledges amino acids as contributors to these normal physiological functions and emphasises their role in exercise-related recovery.

In practice, the Leucine–centric BCAA blend aims to support the body's utilisation of amino acids during and after activity to help maintain muscle integrity and function.
