CircO2 is a fast-acting nitric oxide booster delivered as dissolvable lozenges. Its patented formula activates tongue bacteria to enhance nitric oxide production, increasing levels by 200% within 20 minutes and improving blood flow by 34%—outperforming pills or capsules. By widening blood vessels, CircO2 enhances oxygen and nutrient delivery, supporting cardiovascular health, energy, and endurance. While ideal for older adults, it benefits anyone seeking better circulation, exercise performance, or overall vitality. Its unique oral delivery ensures rapid absorption, making it a standout solution for natural nitric oxide enhancement.
CircO2 works by boosting nitric oxide (NO) production through a unique oral pathway. When the fast-dissolving lozenge melts in the mouth, tongue bacteria convert its nitrates into nitric oxide—increasing levels by 200% in 20 minutes. Key ingredients like L-citrulline and beetroot powder further enhance NO synthesis, promoting vasodilation (blood vessel widening) for better circulation and oxygen delivery. Vitamin C protects NO from breakdown, while hawthorn berry improves absorption. This process enhances blood flow by 34%, supporting cardiovascular health, energy, and endurance more effectively than pills or capsules. By leveraging the mouth’s natural nitrate-to-NO conversion, CircO2 ensures rapid, efficient results.
