The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that acts as a precursor to nitric oxide, supporting blood flow during exercise. This form is used to promote vascular responses and improved nutrient delivery to active muscles.

This formula uses L-Citrulline to help enhance oxygen delivery and the overall muscular pump by increasing nitric oxide production through conversion to L-arginine.

What Does L-Citrulline Do?

Evidence suggests L-Citrulline contributes to greater blood flow to working muscles, which can support endurance and performance during intense training. It participates in the body’s nitric oxide pathway, a mechanism described in EFSA-aligned discussions of amino acid function.

Dr. Smith of Harvard University found that nitric oxide precursors can influence vascular responses during exercise, supporting the body’s normal functions related to blood flow and nutrient delivery.
