The Active Ingredient Is: L-Citrulline

L-Citrulline is a non-essential amino acid that supports normal bodily functions involved in blood flow and exercise performance.

This form is used to boost nitric oxide production and vascular function, contributing to enhanced blood flow and endurance during activity.

What Does L-Citrulline Do?

L-Citrulline plays a role in supporting nitric oxide production, which helps support normal blood flow and muscle performance during intense exercise, a mechanism discussed in sports nutrition research and recognised by EFSA guidance.

Expert evidence indicates that increasing blood flow can support sustained training capacity and muscular endurance during strenuous workouts.
