Today’s environment is characterized by the need to explore new ways to reduce viral infections. Oral Science International discovered Cold & Flu Guard™specifically for people who want to do more. Technology allows us to produce a physical protective barrier where cold and flu viruses take hold and start to develop. Viruses are naturally neutralized and removed BEFORE developing into full blown illness.
Feeling sick isn’t an option anymore, now you can do more!
Our technologies are licensed to the most capable distributors to provide the widest global availability. Currently licensed in the USA, Canada, and Europe, more to follow!

However, not everybody can use Cold & Flu Guard™.
Do not use Cold & Flu Guard™ if you are allergic to any of the ingredients. In case of adverse reactions stop treatment and consult a doctor or pharmacist.
Do not use if you are hypersensitive/allergic to any of its ingredients. Do not use Cold & Flu Guard™ without the approval of your physician if you are pregnant. We suggest that you contact your doctor if you have a high fever or if your symptoms are worse than those of a common cold. These symptoms may be due to something else. Keep out of reach of children to prevent accidents with small parts.
Cold and Flu Guard™ is easy to use and begins working immediately by forming a protective barrier. This is important as you can apply prior to activities where you may be exposed to viruses such as grocery shopping, office work, public transit, meetings and more.
Cold & Flu Guard™ does not have direct components associated with peanuts or nuts, however it is NOT manufactured in a peanut free certified site. As such it is we would not recommend it for those with peanut allergies.
Nasal bleeding has not been reported in Europe were it has been sold for the last 3 years. Bleeding would normally be associated with either trauma or dryness. The components of Cold & Flu Guard™ would moisturize (Hyaluronic Acid), so unlikely to clause bleeding associated with dryness.
No nasal bleeding has been reported in Europe were it has been sold for the last 3 years. When using the spray in the nasal cavity, you can notice a slight stinging sensation, which subsides after a few seconds. It can also cause a short-term runny nose and watery eyes.
No, Cold & Flu Guard™ is safe and well tolerated.
People who are allergic to bioflavonoids can be allergic to Flavobac™.
It is recommended to keep out of reach of pets and not to use on pets as Cold & Flu Guard™ contains Xylitol and the concentration within Cold & Flu Guard™ has not been assessed in pets.
All components of Cold & Flu Guard™ are natural and non-toxic and accidental deep lung inhalation is not expected to affect the person.
Cold & Flu Guard™ and its ingredients have no effect on blood pressure. Patients should consult their doctor if they are concerned about using Cold & Flu Guard™ with their chronic condition.
Cold & Flu Guard™ is designed to Protect and Prevent.
Since the late 1990s, a British team of scientists has been working to achieve a biotechnological breakthrough in pathogen control building on research initiated in the 1930s by Hungarian Nobel Prize winner Szent-Gyorgi. Years of intensive research lead to the development of a complex which had demonstrated efficacy against 40 viruses and bacteria and validated in laboratory tests which comply with European Standards. Flavobac™ was one of the complex born from this research from a former ICI chemist, Ian Ripley.
Flavobac™ is use worldwide under the CITROX™ formulation, both as oral rinse and tooth paste (usually a lower concentration solution containing foaming agents) and for pre-procedural oral antisepsis (usually simply as a low concentration solution). CITROX™ is commercially available In Europe as a mouthwash and tooth paste since 2005 and as a sore throat spray since 2018.
Bioflavonoids have been consumed by humans since the advent of human life on earth, that is, for about 4 million years. They have extensive biological properties that promote human health and help reduce the risk of diseases.
The United States Department of Agriculture has estimated that in the United States, adults generally consume 200–250 mg of bioflavonoids each day.
Flavobac™ is a natural bioflavonoid complex extracted from bitter oranges. The main components are the citrus flavanones naringin and neohesperidin. A wide spectrum of beneficial effects has been attributed to naringin including cardiovascular, hypolipidemic, anti-atherosclerotic, antidiabetic, neuroprotective, hepatoprotective, and anticancer activities [14, 15]. The FDA consider naringin and neoheperidin as GRAS. As indicated in the Food, Drug and Cosmetic act 21 USC 321(s), GRAS substances are exempt from the premarketing clearance. They stated “Flavonoids comprise a group of naturally occurring compounds which are among the most ubiquitous in the plant kingdom. They are found in every family and in nearly every species of the higher plants.” Kuhnau (1976) stated that flavonoids are the most common and active antioxidants.” ”Naringin has been accorded GRAS status as a flavoring agent in food (21 CFR 182.20. Office of the Federal Register, 1981) and hesperidin has been given similar status ( Buckely, 1968.)”
It is recommended to wait 30 minutes before eating or drinking after using Cold & Flu Guard™ so that it has the time to protect the oral and nasal cavities.
No, Cold & Flu Guard™ does not interact with CYP450, so there are no warnings. [This is unlike Statins, certain antidepressants, and other medications].

Yes, there is a robust scientific program ongoing. There are many studies exploring the benefits of the products and of the individual ingredients. The main studies span in vitro to clinical data across targets (viruses, microbiome, resource utilization, real-world evidence).
