CircO2 is formulated to counteract the natural decline in nitric oxide production that occurs with age. Nitric oxide plays a crucial role in vasodilation, relaxing and widening blood vessels to improve blood flow and oxygen delivery. The supplement includes a blend of natural ingredients such as L-citrulline, beetroot powder, hawthorn berry, vitamin B12, vitamin C, magnesium, and sodium nitrite. These ingredients collectively support cardiovascular health, energy levels, cognitive function, and joint comfort.

How Does It Work? ๐ฌ

CircO2 works by boosting the body's natural production of nitric oxide, primarily through sublingual absorption via quick-dissolving lozenges that leverage oral bacteria to catalyze conversion of nitrates to nitric oxide. L-citrulline is converted into L-arginine in the kidneys, then to nitric oxide. Beetroot extract provides dietary nitrates converted by oral bacteria to nitric oxide, while vitamin C protects nitric oxide from oxidative damage and supports endothelial function. This enhanced nitric oxide production leads to widened blood vessels, improved blood flow, better oxygen delivery to muscles, brain, and organs, supporting energy, stamina, cognitive clarity, and healthy blood pressure.

More Stamina Anyone?
I started using CircO2 tablets three weeks ago. Already I have noticed an improvement in my energy levels as well as physical and mental stamina. It seems these tablets are helping because I find I have a reservoir of mental energy left at the end of the day that I didnโt have before. Iโm glad I tried this product!

Great stuff
I bought CircO2 about a month ago. It took about 2 weeks of taking it and I started noticing that I had more energy. I will keep taking this.
