The Central Ingredient Stands: L-Citrulline DL-Malate

L-Citrulline DL-Malate is a nonessential amino acid derivative that helps nitric oxide output, and keeps blood flow steady during exercise.

This blend pairs L-Citrulline with malate to aid absorption and utilisation in the body, contributing to endurance related processes during workouts.

What Exactly Does L-Citrulline DL-Malate Do?

It helps to support nitric oxide production, which sustains blood flow and may help endurance during exercise in healthy people, which aligns with findings showing improved performance and less fatigue in athletic contexts.

Dr. Pérez-Guisado from a university found that citrulline malate supplementation can improve exercise performance and delay fatigue in athletic groups.
