The Active Ingredient Is: L-Citrulline

L-Citrulline is a not strictly essential amino acid that turns up in foods and in the body, and helps with the production of nitric oxide. This ingredient helps with normal blood flow and is involved in metabolic processes linked to exercise performance.

This form is a well known amino acid that acts as a starter in the nitric oxide pathway, helping with circulatory support during physical activity.

What Does L-Citrulline Do?

Studies show that L-Citrulline boosts nitric oxide production, which can help with blood flow, nutrient delivery, and endurance during training. This lines up with EFSA and NHS style ideas of nitric oxide precursors and nutrition for daily wellness.

In the context of exercise, it helps sustain performance by promoting better delivery of oxygen and nutrients to working muscles, as described in nutrition research literature.
