General Description 📝

CircO2 is a nitric oxide-enhancing supplement from Advanced Bionutritionals designed to restore natural nitric oxide levels that decline with age. It improves blood circulation, energy, stamina, cognitive sharpness, cardiovascular performance, and overall well-being. The fast-dissolving lozenge works through oral bacteria interaction for rapid nitric oxide production, leading to benefits such as better oxygenation, mental focus, and physical endurance.

How Does CircO2 Work? ⚙️

CircO2 promotes nitric oxide production by leveraging the oral bacteria that convert dietary nitrates into nitric oxide, a critical molecule for vascular health. The lozenge dissolves slowly in the mouth maximizing this conversion, unlike traditional capsules that pass directly to the stomach. This results in improved endothelial function, vasodilation, increased blood flow, and oxygen delivery to muscles and brain, supporting energy, stamina, mental clarity, healthy blood pressure, joint comfort, and physical performance.

Supports Circulation and Energy

I've been taking CircO2 for a long time and it works. When I forget to take it, I feel sluggish. It helps my blood circulation especially since I don't get tingling in my fingers during sleep. I take it morning and night.
