BioSure PRO Protective Nasal Spray is a microemulsion formula, that is applied as a plume of droplets rather than a squirt, so it creates a temporary physical barrier in your nasal passages that blocks the virus spike proteins from entering the cells ACE-2 receptors in your nose. This helps block the first step of infection at the main entry point and it also helps prevent the virus from multiplying that physically blocks airborne viruses from attaching to the cells in your nose.

The key ingredient is ELAH (Ethyl Lauroyl Arginine Hydrochloride), that has been safely and effectively used in a globally recognised mouthwash to block the growth of bacteria in the mouth.

Clinical evaluations in humans and in the lab have proven the effectiveness of ELAH at blocking airborne viruses, including RSV (common cold), influenza (flu) and COVID-19 delta and omicron variants.

Basically if the virus can't enter these cells, it cannot cause infection and it cannot reproduce.
