The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that acts as a precursor to nitric oxide, supporting vasodilation and blood flow to muscles. This helps with pumps and endurance during exercise. It is commonly used in supplementation to optimise supply of nutrients to working muscles.

This form is widely utilised in sports nutrition to enhance nitric oxide production and improve exercise performance. The ingredient is typically added in clinically effective amounts to support vascular responses during training.

What Does L-Citrulline Do?

L-Citrulline aids in the production of nitric oxide, which is involved in smooth muscle relaxation and blood flow to tissues. Research suggests improvements in exercise performance and reduced fatigue may occur with increased availability of this amino acid.

Dr. Pérez-Guisado of the University of Murcia found that higher intake of L-Citrulline can improve endurance and performance in athletes, supporting its role in vascular function and sustained effort. EFSA-style evidence supports the link between enhanced blood flow and exercise outcomes.
