Nutritional Information

The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid used by the body to support normal blood flow and muscle recovery processes.

This powder provides a single-ingredient formulation in a pure form, with Kyowa Quality ensuring high purity and consistency in amino acid production.

What Does L-Citrulline Do?

L-Citrulline is involved in increasing nitric oxide production, which helps to support vascular tone and blood flow to muscles and organs. It also serves as a precursor to L-Arginine, contributing to pathways that support exercise performance and post-exercise recovery.

These functions align with normal physiological processes that support circulatory health and physical performance, with the nutrient working alongside other body systems to optimise oxygen delivery and nutrient transport.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
