The Claim

Nitric oxide nasal spray reduces viral infectivity by over 3 log10 (>99.9%) within 2 minutes in vitro against SARS-CoV-2 variants including Alpha, Beta, Gamma, Delta, Omicron BA.1, and XBB 2.0, with inactivation occurring within 30 seconds to 2 minutes depending on the variant.

In plain English

A nose spray with nitric oxide quickly kills over 99.9% of the COVID-19 virus and its variants in lab tests, working in as little as 30 seconds.
