L-Arginine, L-Citrulline & Brain Blood Flow: The Nitric Oxide Connection

By HoneyPezil Research · Reviewed by Dr. Alan Foster, M.D. · Updated June 2026

The nitric-oxide amino acids are the engine of HoneyPezil. Here's why L-Arginine and L-Citrulline matter for brain blood flow.

Why Brain Blood Flow Matters

Your brain uses about 20% of your body's oxygen. Healthy cerebral circulation delivers the oxygen and nutrients neurons need to fire, focus, and form memories.

L-Arginine & Nitric Oxide

L-Arginine is converted directly into nitric oxide, which helps relax and widen blood vessels for healthy blood flow (PubMed).

L-Citrulline & the NO Cycle

L-Citrulline is recycled back into arginine, creating a continuous cycle of nitric oxide production that keeps blood flow steady (PubMed).

In HoneyPezil

Honey Pezil pairs four nitric-oxide forms (L-Arginine, L-Arginine AKG, L-Citrulline HCL, L-Citrulline Malate) with Niacin and Beta-Alanine — see the full ingredients list and the current HoneyPezil discount on the HoneyPezil official website.

These nutrients support healthy circulation and are not a treatment for any condition. Consult your doctor before use if you take medication for blood pressure or blood thinners.
