It is scientifically proven that CircO2 can improve nitric oxide levels in the body that is responsible for the endless energy, healthy blood pressure, and steel-trap memory. It works for individuals of any age, but prominent effects are observed at old-age. The researchers have conducted a study in which they measured the nitric oxide levels of the study participants before they used the CircO2 or l-arginine. The levels were measured again after 20 minutes and one hour. The levels were boosted by 200% in participants who used CircO2 in just 20 minutes. Whereas, no improvement was observed in the group taking 1-arginine, even after an hour. The enhanced levels of nitric oxide provided by this formula contribute to the majority of its beneficial effects.
