The Core Ingredient Is: L-Citrulline Malate

L-Citrulline Malate is a non essential amino acid compound that helps to support nitric oxide production for better blood flow during workouts.

This form blends citrulline with malate, giving a hydrated, pump oriented ingredient used to aid vascularity and endurance in training contexts.

What Does L-Citrulline Malate Do?

L-Citrulline Malate takes part in nitric oxide pathways to promote vasodilation and improved nutrient transport to muscles, supporting performance related processes during effort. This mechanism sits within normal exercise physiology as discussed in study literature.

Dr. Gonzalez from the university found evidence backing increased vasodilation and exercise performance with this compound.
