CircO2 is a natural dietary supplement that helps your body create more nitric oxide. More N-O means better circulation … and more energy, more vitality, and even improved sexual function.*


CircO2 is a natural dietary supplement that helps your body create more nitric oxide. It begins working within minutes, but its effects last for hours. CircO2’s patent-pending formula works in two phases. The unique delivery system begins to work almost instantly, as N-O is released and absorbed rapidly into the bloodstream, where it helps your body relax your arteries. Nutrients from the lozenge also pass into the digestive tract and are absorbed. From there, they are metabolized to promote even more production of N-O. More N-O means better circulation … and more energy, more vitality, and even improved sexual function.*

Revolutionary Patent-Pending Nitric Oxide Indicator Strips Reveal Your N-O Status Instantly
How do you know if you’re deficient in N-O? And how do you know CircO2 is helping to restore your body’s N-O? It’s simple: you take one of our revolutionary Patent-Pending Nitric Oxide Indicator Strips. Two N-O indicator strips come in every box of CircO2. The test results are visible evidence that when you stick to a daily regimen of CircO2, your body begins producing more nitric oxide.
