The Active Ingredient Is: L-Arginine

L-Arginine is an amino acid used by the body as a precursor to nitric oxide, supporting normal vascular function. This form is L-Arginine, a naturally occurring component of many proteins and metabolic processes.

The capsule contains it as a dedicated amino acid supplement, with vitamin C included separately to provide antioxidant support.

What Does L-Arginine Do?

Scientific research suggests L-Arginine participates in nitric oxide production, which can support normal circulation and endothelial function. Dr. Rosolová of Charles University found that oral L-Arginine augments endothelium-dependent NO production and vasodilation.

This information relates to normal physiological roles and vascular health as recognised in peer-reviewed literature.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
