Cold and Flu Guard Personal Protective Equipment

60ml bottle

Description & Mechanism of Action

Today, feeling sick isn’t an option. Today, we have heightened sensitivity to virus infection and control. This new reality is the new norm. This novel product is deliberately designed to relieve and protect against the effects of viruses. Studies conducted by independent laboratories using a recognized medical methodology have demonstrated that Cold & Flu Guard™ kills 99.94% of the tested enveloped viruses in 5 minutes. The efficacy of Cold & Flu Guard™ is created by the synergy between its two main ingredients:

Hyaluronic Acid (High Molecular Weight Level)

  • Creates a physical barrier that coats the mucosa to encapsulate and isolate the virus from entering the oral and nasopharyngeal cavities
  • Delivers Flavobac™ to the main sites of exposure to the virus and its reproduction

Flavobac™ (Patented, plant-based, specific complex of bioflavonoids, a citrus extract)

  • Destroys the virus envelope, deactivating and killing the viruses, neutralizing their ability to infect cells
  • Flavobac™ has already been shown to kill the human coronavirus, influenza virus, respiratory syncytial virus (RSV) and rhinovirus, including the most difficult strains of cold and flu H5N1 (bird flu), H1N1 (swine flu), and SARS-CoV

With Cold & Flu Guard™, you are providing highly effective and advanced protection for yourself, colleagues, patients and your families. 90% of dentists and dental hygienists are confident that Cold & Flu Guard™ will provide highly effective and advanced protection for themselves.
