General Description

CircO2 oxygen booster and circulation support box with 30 quick-dissolve tabs

CircO2 is formulated to counteract the age-related decline in nitric oxide production that affects blood vessel dilation, oxygen flow, brain function, stamina, sexual performance, and blood pressure. It includes a proprietary blend of natural ingredients to boost nitric oxide by up to 200% within minutes.

How Does It Work?

CircO2 contains ingredients like L-citrulline and beetroot extract which support nitric oxide synthesis in the body. L-citrulline converts to L-arginine, which is then converted to nitric oxide, a key molecule that promotes vasodilation and healthy blood flow. Vitamin C acts as an antioxidant protecting nitric oxide molecules. The quick-dissolving tablet formulation allows fast absorption and onset of effects.

Pain reduced with CircO2

Before I started taking CircO2 in 2023, I had pain in my hands and arms that affected my sleep. After taking CircO2, my pain was reduced and now I can sleep with almost no pain.
