The Active Ingredient Is: L-Citrulline

L-Citrulline is a not essential amino acid tied to the body's production of nitric oxide, which supports healthy blood flow and nutrient delivery during activity.

This form is a simple amino acid frequently used to back metabolic processes linked to exercise performance and muscle function.

What Does L-Citrulline Do?

L-Citrulline helps to support and maintain normal blood flow by supporting nitric oxide production, which plays a role in vascular function and nutrient delivery during physical activity, [which is important for daily stamina].

Dr. Bailey of University of Exeter found that higher circulating L-arginine can be associated with enhanced nitric oxide–dependent signalling, which aligns with how nitric oxide supports circulation and endurance during exercise.

The mechanism aligns with how nitric oxide supports circulation and endurance during exercise, contributing to bodily performance in a normal, healthy range.
