The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that helps to produce nitric oxide, which boosts blood flow and vascularity during workouts. This form is a free-form amino acid used in supplements to help support performance and hydration in training sessions.

What Does L-Citrulline Do?

L-Citrulline helps boost nitric oxide production, which can support better blood flow and muscle fullness during workouts, and it helps support endurance and the body’s response to exercise related stress, aligning with normal physiological functions in active individuals. Its role in supporting circulatory and metabolic processes helps optimise daily training performance and recovery without stimulants. This supplement isn't meant to diagnose, treat, cure, or prevent any disease.
