How Does It Work?

Nasaleze Cold & Flu Blocker contains a cellulose powder, which when inhaled into the nose forms a mucous-like gel that stops many airborne germs and viruses reaching the sensitive lining of the nose. It creates a physical barrier which shields, protects, and deactivates airborne germs and viruses that are inhaled into the nasal cavity.

Fast-acting protection

Nasaleze Cold & Flu contains a cellulose powder that is inhaled into the nose. Once in the nasal cavity, the powder forms a mucous-like gel that stops many airborne viruses from reaching the sensitive lining of the nose. It creates a physical barrier, providing an extra layer of protection against germs. By trapping, absorbing and neutralising airborne germs, Nasaleze Cold & Flu provides continuous protection from airborne viruses that are inhaled via the nose.



The core ingredient is Hydroxypropyl methylcellulose (HPMC) supported by odour-controlled garlic and peppermint. The powders in Nasaleze Cold & Flu Blocker have been selected to provide the optimum barrier effect with deactivating properties.


Who is it for?

It is suitable for anyone who wants added protection from airborne germs, which are the most common way people catch cold and flu viruses. Using Nasaleze Cold & Flu Blocker before exposure to a crowded public area will make it much more difficult to pick up colds and germs. It can be used by pregnant and breast-feeding women, as well as children over three years old. Read product reviews here.

How to Use Nasaleze

The usual dose is one puff of powder up each nostril three times a day. Each bottle contains 200 sprays, which equates to a 30 day supply. For maximum efficacy, it is necessary to maintain a constant layer of gel across the lining of the nose. It is therefore recommended that you re-administer the product after blowing your nose to renew the barrier. Click here for more guidance.
