General Description

CircO2 is a fast-dissolving lozenge dietary supplement developed by Advanced BioNutritionals. Unlike traditional pills or capsules, it was uniquely created to quickly and effectively boost nitric oxide levels in the body. The product is positioned as a powerful solution to combat the natural decline of nitric oxide that occurs with aging (up to an 85% drop by age 80), helping restore vibrant energy, memory, blood circulation, sexual performance, and healthy blood pressure levels.

How It Works

Based on a breakthrough discovery from MIT, CircO2 works by triggering nitric oxide production directly in the mouth, rather than the stomach. The natural bacteria present on your tongue convert the nitrates in the formula straight into active nitric oxide. The lozenge dissolves quickly on the tongue, allowing this process to happen efficiently. In clinical tests, this specific delivery method increased nitric oxide levels by an astonishing 200% in just 20 minutes and boosted overall blood flow by 34%.

🔋 Reduction of fatigue (especially afternoon sluggishness).

Frequently Asked Questions

Is CircO2 safe?
Yes, it is generally well-tolerated. However, always consult a physician if you have pre-existing medical conditions or are currently taking prescription medication.
How long does it take to feel the effects?
Many users report an increase in energy and clarity in less than 30 minutes. For long-term health benefits (such as blood pressure and joint support), use consistently for a few weeks.
Do I need to swallow the lozenge?
No. You should allow the lozenge to dissolve completely on top of your tongue for optimal sublingual absorption.
Does it contain caffeine?
No. The clean energy you experience comes directly from improved oxygen and nutrient delivery to your cells, not from artificial stimulants.
Where can I buy it?
It is available exclusively through the official website to guarantee product authenticity and protect your 90-day money-back guarantee.
Do I need to stop using mouthwash?
Analysis shows that antiseptic mouthwashes and fluoride toothpastes can destroy the beneficial mouth bacteria needed to produce nitric oxide. The manufacturer suggests reconsidering their frequent use.
