The Essential Ingredient Is: Leucine (L-Leucine)

Leucine is a vital branched‑chain amino acid involved in normal muscle protein synthesis and tissue upkeep.

This form is supplied as free-form L‑Leucine within a BCAA blend, aiding rapid absorption and availability for metabolic processes linked to muscle repair and adaptation to training.

What Does Leucine Do?

Leucine participates in muscle protein synthesis and helps with energy production during exercise, contributing to muscle upkeep and repair after training sessions as described in EFSA-supported discussions on amino acid function.

Its actions support normal athletic performance by helping muscle turnover and recovery without suggesting disease treatment or prevention.

This product is not meant to diagnose, treat, cure, or prevent any disease.
