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

Leucine is an essential amino acid within the branched-chain family that helps steer the body's muscle protein synthesis processes.

This ingredient is a core part of BCAA blends used to support training adaptations and recovery from intense workouts.

What Does Leucine Do?

Leucine helps trigger muscle protein synthesis and supports the activation of the mTOR pathway, which aids muscle growth after training. This function is consistent with guidance on normal muscle function and protein metabolism.

EFSA-aligned understanding emphasises leucine’s role in supporting the body’s muscle maintenance processes during and after exercise.
