L-citrulline is a non-essential amino acid that acts as a precursor in creating nitric oxide, supporting normal aspects of blood flow and circulatory function. This form is 100% pure L-citrulline powder, offered as the sole active ingredient to aid exercise-related vascular activity.

What Does L-citrulline Do?

L-citrulline engages in the body’s nitric oxide pathway, which helps relax blood vessels and supports blood flow during activity. It can help foster endurance and pump effects linked to resistance training and cardiovascular health considerations outlined by EFSA guidance.

In healthy individuals, this nutrient contributes to normal cardiovascular function and athletic performance through its role in nitric oxide production. This bracketed aside helps to emphasise practical daily relevance (which is handy for daily workouts).
