Leucine is an essential amino acid and a core branched-chain amino acid supplied as a pure, single-ingredient supplement. The product is vegan and allergen free, giving a single active ingredient that’s naturally found in dietary protein.

This form arrives as L-leucine, a naturally occurring dietary amino acid used to help support muscle protein metabolism and recovery after exercise.

Leucine helps trigger the mTOR pathway, which supports muscle protein synthesis in response to training and protein intake. Dr. Koopman from the University of Cambridge found that leucine directly activates this pathway, helping with recovery and the maintenance of lean muscle after training.

This mechanism sits with the role of amino acids in backing normal muscle function and recovery after physical activity.
