π Buy CircO2 Nowπ General Description
CircO2 is designed to boost nitric oxide levels rapidly by using a patented formula delivered as fast-dissolving lozenges that activate nitric oxide production in the mouth through tongue bacteria. This unique delivery helps raise nitric oxide levels by 200% within 20 minutes and improve blood flow by 34%, which no pills or capsules can match.
π¬ How Does It Work?

L-Citrulline molecule
Nitric oxide production starts in the mouth via bacteria on the tongue converting nitrates into nitric oxide. CircO2's lozenges dissolve in the mouth to kickstart this process quickly. Key ingredients like L-citrulline and beetroot powder increase nitric oxide synthesis, leading to vasodilation that relaxes and widens blood vessels, improving blood flow and oxygen delivery. Vitamin C protects nitric oxide from oxidative damage, and other components like hawthorn berry enhance absorption.
