The Active Ingredient Is: L-Arginine (L-Arginine HCl)

L-Arginine is a semi-essential amino acid that acts as a key substrate for nitric oxide synthesis in the body.

This form is L-Arginine hydrochloride, a pharmaceutical-grade version sold in capsules described as a convenient source for boosting available L-arginine levels.

What Does L-Arginine Do?

L-Arginine is involved in nitric oxide production, which relates to blood flow regulation and muscle oxygenation in athletic contexts, together with a role in creatine biosynthesis that supports muscular energy during high-intensity activity. These mechanisms align with EFSA-style function concepts.

Dr. Wu from the University notes that nitric oxide plays a role in circulation and nutrient delivery, contributing to physiological processes involved in normal exercise performance.
