L-Citrulline is an amino acid that helps in nitric oxide precursor routes, supporting blood flow and nutrient delivery to working muscles. This mix includes Citrulline Malate as part of the blend.

This blend uses Citrulline Malate to support nitric oxide production within the nitric oxide precursor system, contributing to energy and endurance during activity.

What Does L-Citrulline Do?

L-Citrulline helps to keep normal blood flow by supporting nitric oxide production, which can aid the delivery of oxygen and nutrients to muscles during exercise. This aligns with EFSA guidelines on nitric oxide precursors and how they support vascular function.

Overall, it helps sustain performance by backing the body's natural circulation processes during training.
