A nose spray with nitric oxide might quickly lower the amount of COVID-19 virus in your body, cutting it by 95% in one day and 99% in three days for people with mild symptoms.

91%

A nasal spray with nitric oxide helps people with mild COVID-19 by reducing the amount of virus in their body over a week of treatment, making them less sick.

89%

A nose spray with nitric oxide can quickly kill over 99% of flu, COVID, and cold viruses in lab tests.

84%

A nose spray with nitric oxide helps people with mild COVID-19 get rid of the virus faster. When used several times a day for over a week, it reduces the virus amount 16 times quicker than a placebo spray by the second and fourth days.

83%

A nose spray with nitric oxide was tested on adults who had mild COVID-19. The study found that no one had any serious side effects from using the spray for 9 days.
