General Description
CircO2 is a nitric oxide boosting formula developed by Advanced Bionutritionals. It is formulated as a quick-dissolving sublingual lozenge that boosts nitric oxide production by stimulating multiple biological pathways, including nitrate conversion via beetroot and amino acid precursors like L-citrulline. Nitric oxide is a critical molecule for vasodilation, blood flow, oxygen delivery, and cardiovascular health. CircO2 targets the natural decline in nitric oxide that occurs with aging, aiming to improve symptoms such as fatigue, brain fog, poor circulation, and reduced stamina.
How Does CircO2 Work?
CircO2 works by supporting the body's natural production of nitric oxide, a gas that relaxes and widens blood vessels to improve circulation and oxygen delivery. The supplement's sublingual lozenge form allows it to dissolve under the tongue for fast and efficient absorption directly into the bloodstream, bypassing the digestive system. It uses a dual-pathway approach to stimulate nitric oxide via nitrate conversion from beetroot and enhanced amino acid (L-citrulline) availability, leading to increased blood flow, enhanced stamina, sharper mental focus, and cardiovascular support.
Nitric Oxide levels increase rapidly with CircO2
