The Active Ingredient Is: L-Leucine

L-Leucine is an essential amino acid required for normal protein synthesis and muscle turnover. It is supplied in free-form form in many sports nutrition blends to support building blocks for tissue protein.

This amino acid is naturally present in dietary proteins and is commonly provided as a high-quality free-form amino acid in supplements.

What Does L-Leucine Do?

L-Leucine helps maintain muscle protein synthesis by supporting the mTOR pathway, contributing to muscle repair and recovery after activity, in line with EFSA and NHS context on amino acid function.

Scientific research suggests that essential amino acids, including leucine, play a key role in sustaining lean muscle when intake supports normal metabolism; this is noted by researchers at a major university in validation of muscle maintenance concepts.
