What is Cold & Flu Guard?

Cold & Flu Guard™ is a spray that forms a protective barrier in the mouth and nose. It contains a patented formulation made of citrus extract called Flavobac™ that will protect yourself from contracting and transmitting the most common strains of viruses, so you can feel confident living your life. Because today, feeling sick isn’t an option anymore.

Benefits of Flavobac™

-* Proven effective against most difficult strains of cold and flu (ie: bird flu/H5N1, swine flu/H1N1, H3N2, SARS-cov, Norovirus, Rhinovirus, and more)

  • Kills viruses in less than 5 minutes

  • Coats the back of the nose and throat where the viruses take hold and start to develop
  • Traps and neutralizes cold and flu viruses
  • Higher anti-viral activity than antiseptics

Benefits of Cold & Flu Guard

Contains Flavobac™, a plant-based, patent-protected, specific complex of bioflavonoids

Contains hyaluronic acid, a barrier that coats the mucosa and primes the neutrophils, allowing Flavobac™ to neutralize bacteria and viruses that enter the mouth and nasal cavities

Efficient - Designed as an oral and nasal spray to target most common routes of infection

Each bottle is 22 working days (about a month)

Flavobac™ acts within 1 minute of administration, and kills pathogens within 5 minutes

Reapplication at 3 hours

Directions for Use

Apply 1 to 3 sprays per nostril and repeat in the mouth by avoiding direct deep inhalation. Repeat 2 to 3 times per day. Continue to use 2 days after symptoms subside.

When using the spray in the nasal cavity, you may notice a slight stinging sensation at first; this subsides after a few seconds. This product may also cause a short-term runny nose.
