The Active Ingredient Is: Leucine (essential amino acid)

Leucine is an essential amino acid that forms part of branched-chain amino acids used to support normal muscle function and metabolic processes related to exercise.

This formula also includes the other branched-chain amino acids, isoleucine and valine, which help provide energy for working muscles and support glucose uptake.

What Does Leucine Do?

Leucine is involved in activating the mTOR pathway, which supports muscle protein synthesis and maintenance during periods of activity. Isoleucine and valine contribute to energy supply and endurance during exercise, aiding muscle function as described in available evidence.

This information reflects known roles of branched-chain amino acids in normal physiology and energy metabolism.
