The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that supports nitric oxide production, contributing to improved blood flow and muscular endurance during activity.

This form is a natural amino acid commonly used to help sustain performance and is present in many high-quality pre-workout formulas for its role in supporting circulatory function.

What Does L-Citrulline Do?

Dr. Chappell of a university found that L-Citrulline can enhance aerobic and anaerobic performance and reduce fatigue by increasing blood flow and oxygen delivery to muscles.

These effects align with EFSA-style guidance, emphasising normal cardiovascular and muscle function during exercise.
