Studies find support for Xlear Nasal Spray's virucidal properties

By David Salazar - 10/05/2020

Xlear has completed additional virucidal testing for Xlear Nasal Spray against the novel coronavirus, SARS-CoV-2. The testing, conducted in separate studies at Utah State University and the University of Geneva in Switzerland found the grapefruit seed extract used in Xlear Nasal Spray has potent virucidal activity against the virus. 

These results join earlier results from the University of Tennessee whose data showed xylitol to have antiviral properties. Specifically, xylitol inactivates viruses by blocking the attachment between viral surface proteins and receptor proteins in human cells. 

Xlear noted that this means Xlear offers a two-pronged nasal spray in fighting the spread of COVID-19. 

“We are delighted to be working with Dr. Gustavo Ferrer of the Pulmonary Institute of Aventura to expedite further clinical research of this important product,” said Nathan Jones, CEO and founder  of Xlear. “These latest data show that at clinically relevant concentrations (at the concentration of the Xlear Nasal Spray), xylitol blocks adhesion of more than 99.9% of the Sars-Cov-2 virus, the [grapefruit seed extract] working as a virucidal then inactivates more than 99.9% of SARS-CoV-2, which represents a compelling feature for the product. This potent 1-2 punch of blocking viral adhesion and virucidal action is consistent with what the invitro research shows.”

Xlear said that is has expedited production increases of its Xlear Nasal Spray products and is working to ramp up production in the near future. 

“We have been working with Xlear for a number of months now and are impressed with the antiviral and virucidal data generated at world-class research institutions against SARS-CoV-2,” Farrar said. “The Xlear Nasal Spray has the potential to be an important near-term airway cleansing product and therapeutic, and given it is already available at over 50,000 retailers nationwide it could be the most readily available product to help slow the spread of the Sars-Cov-2 virus. Another great feature of the Xlear Nasal Spray is that it is entirely complementary to other prevention measures such as PPE and vaccines.”
