CircO2 by Advanced Bionutritionals is a dietary supplement designed to support nitric oxide production in the body. Nitric oxide plays a role in blood flow, circulation, and oxygen delivery, which are important for overall cardiovascular and physical function. Research cited by the manufacturer suggests that nitric oxide levels naturally decline with age.
Unlike traditional capsules or tablets, CircO2 is delivered as a fast-dissolving lozenge. According to research referenced by the company, nitric oxide production begins in the mouth, where specific oral bacteria help convert dietary nitrates into nitric oxide. The lozenge format is intended to support this process by dissolving on the tongue rather than being digested in the stomach.
