NasalGuardCold&FluBLOCK Gel for Protection from Cold and Flu and Blocking Virus-Sized Particles (Menthol) - Drug-Free and Proven Safe - Over 150 Applications Per Tube (0.1 oz, Pack of 1)

Well it seems to work. I use it when going into a busy public place, as I'm immune compromised. I've not caught anything yet, so who knows? It could be this, or the mask I wear, or the hand sanitiser I use. I'll carry on using it though, as it's odour free and gentle on the nose.

I work in a school and since using this I do not catch as many bugs! I'm pretty certain this works!!

Amazing product that should be in everyone's cupboard, works every time. Not great value for money with the amount and size you get but it lasts a long time. Too much packaging for something this small, that's the only reason for 4 stars.

Really great! The best! Great price and great service - Thank you.

Bought this one as had the allergy version which was great. Thought I'd try the menthol version. But can't smell any menthol. Maybe my nose is blocked...

I've used this for the past 2 years. Usually I'll have cold after cold but this stuff is great. Yes you will probably pick up a cold through winter but on the whole this little tube will dramatically reduce the number you get. It's the best product of it's kind. Oh and a little goes long way so it's not as expensive as it looks. Would highly recommend this to anyone.

Seems to do the trick😊. I work with a lot of people, it's not always easy to social distance, so I bought this to protect myself as well as wearing a mask. Haven't had a cold or anything since using. I'm not saying it protects against dreadful covid19 but... I just felt better protected,... Every little helps eh😉

We used it because the visited family had viruses. After 2 days my whole family got viruses.
