The Active Ingredient Is: L-Citrulline

L-Citrulline is a non-essential amino acid that participates in the production of nitric oxide, supporting vasodilation and blood flow during exercise. This form is the free amino acid used by the body and is commonly included in pre-exercise formulations to support athletic performance.

What Does L-Citrulline Do?

L-Citrulline supports nitric oxide production, which is involved in widening blood vessels to promote enhanced blood flow and muscle pumps during training. Research suggests this can improve acute performance by increasing oxygen delivery and reducing fatigue during high-intensity work. Dr. Cutrufello of the University found that this mechanism can enhance exercise performance.
