The Active Ingredient Is: Leucine (L-leucine)

The Essential Ingredient Is Leucine (L-leucine) and it stands for an amino acid that counts when it comes to building and repairing muscle tissue.

Leucine is an essential amino acid that helps support a broad amino acid blend sourced mainly from whey protein concentrate, giving a full profile of amino acids needed for recovery and adaptation after exercise.

What Does Leucine Do?

Leucine helps trigger muscle protein synthesis, supporting recovery after training. Research suggests leucine acts as a trigger for this process, contributing to muscle maintenance in active individuals.

The presence of leucine in combination with other amino acids in this blend supports the body's normal processes of tissue repair and energy provision during and after exercise, aligned with recognised nutrition guidance.
