The Active Ingredient Is: L-Leucine

L-Leucine is an essential amino acid that contributes to normal protein synthesis and muscle maintenance. The BCAA blend in this product includes L-Leucine sourced from vegan, fermented plant materials.

This form is part of a vegan amino acid profile alongside other BCAAs and is paired with absorption-enhancing ingredients to support effective uptake of amino acids during exercise.

What Does L-Leucine Do?

L-Leucine is involved in triggering the body’s protein building process, helping to support muscle function and recovery after activity. [This means it plays a key role in helping muscles recover after training, and it’s easy to add to your routine.]

This mechanism is enhanced by other components in the formula that aid amino acid absorption and utilization, contributing to the overall efficiency of protein synthesis within the body. It also helps to support and optimise how amino acids get used while you train, which matters for daily performance.
