CircO2: Unlock Your Vitality & Energy Naturally

CircO2 is a nitric oxide boosting formula designed to support healthy circulation, heart health, energy, stamina, immune function, and overall vitality without stimulants. It uses a blend of natural ingredients in quick-dissolving lozenges that stimulate the production of nitric oxide in the body, enhancing blood flow and cardiovascular health.

General Description 🔍

CircO2 Box Packaging

CircO2 is a nitric oxide boosting formula developed by Advanced Bionutritionals, designed to support cardiovascular health, energy, and circulation. It comes in a fast-dissolving lozenge that promotes nitric oxide production in the mouth by interacting with oral bacteria, leading to enhanced blood flow throughout the body.

How Does it Work? ⚙️

Nitric Oxide Levels Chart

CircO2 works by stimulating the body's production of nitric oxide, a gas that relaxes and widens blood vessels (vasodilation), thereby improving blood flow and oxygen delivery to tissues. The lozenge dissolves in the mouth, allowing its ingredients to mix with beneficial bacteria that convert nitrates into nitric oxide, which quickly raises nitric oxide levels, resulting in enhanced vascular compliance, lowered blood pressure, and restored endothelial function.
