In the world of health supplements, few products have generated as much buzz as CircO2 Oxygen Booster and Circulation Support. With claims of enhancing blood flow, increasing oxygen delivery, and supporting heart and brain function, CircO2 is gaining attention, especially among older adults and those seeking a natural way to fight fatigue, mental fog, and poor circulation.
But does it work? In this article, we’ll take a closer look at how CircO2 works, its key ingredients, benefits, and whether it might be the right supplement for your wellness journey in 2025.
What Is CircO2?
CircO2 is a nitric oxide (NO) supplement developed by Advanced Bionutritionals. It’s designed to help your body naturally increase nitric oxide production, a vital molecule that supports circulation, oxygen flow, and vascular health.
Unlike traditional pills or powders, CircO2 comes in a dissolvable tablet form. You place it under your tongue, where it dissolves and is absorbed directly into the bloodstream—no water required.
The goal? More nitric oxide = better blood flow = more oxygen to your brain, heart, muscles, and organs.
How Does CircO2 Oxygen Booster Work?
Nitric oxide is a naturally occurring molecule in your body. It helps relax and widen blood vessels, allowing blood (and oxygen) to flow more freely. But as we age, our ability to produce nitric oxide declines, often starting in our 30s.
This decline can lead to:
- Fatigue
- Cold hands and feet
- Poor memory or mental fog
- Low stamina and exercise performance
- Slow wound healing
CircO2 Oxygen Booster works by using powerful ingredients that support nitric oxide production, helping restore healthy circulation and oxygen delivery.

An amino acid that helps the body produce L-arginine, which is then converted to nitric oxide.
- Enhances blood vessel dilation
- Supports energy and stamina

One of the most powerful natural nitric oxide boosters.
