LUCA V-Defense™ Nasal Spray with Lambda Carrageenan, Menthol, and Eucalyptol – Drug-Free Nasal Congestion Relief – Moisturizes Nasal Passages and Reduces Contaminant Adhesion – 0.67 fl oz (200 Sprays)

Very effective product! I’ve used this spray before and during multiple big conventions this year like Comic Con and have not gotten sick! High recommend to add your sick prevention routine!

My husband is severely immuno-compromised so it is important that we both stay healthy. We use masks when in situations of high risk but use this product in all other public situations. We have been healthy since his transplant with the help of this product.

I have been using this for a while, I consider myself to be my own test since I use this when I go to the gym or other public spaces. I almost never get sick as a rule so have no way of knowing if it's working or not.

Very easy to use, not uncomfortable or anything. I don't like nasal sprays--I have pretty bad allergies and even though all my doctors told me to use nasal sprays, I just can't do it. I hate the ones for migraines too; they're just likely to make me vomit sooner. So, when I say that this is comfortable and easy to use... that means a lot for me lol.I can't really prove whether this prevented covid, but I used it religiously on a cruise and did not get sick. Of course I'm up to date on my boosters, masked in busy areas, used CPC mouthwash, etc. too.

On my third bottle..not sure if it works but it’s worth the peace of mind in a large group

Great product. We use it before all flights, before concert…. wherever there’s a crowd basically. And we haven’t gotten sick. We bought this because my daughter would pick up colds when traveling and also has allergies to dust. It’s been good overall after using this product. We pack it in our personal bags and TSA never says anything.

After two uses of this product in a day, especially if breathing in while spraying as was directed, I got a sinus headache followed by allergic reaction in the mouth, both of which are very unusual events for me. I am now waiting for the reaction to heal. If I try it again, it will be without actively breathing it in while spraying.

This is a fantastic product! I have tried various nasal sprays and this one shines above the rest. First, it's important to consider that this is not a spray to be used after being exposed to airborne viruses. This is a preventative measure before exposure and if used for that purpose, while it is hard to prove effectiveness, I can say that I feel confident it works! I've tried other products that all have limitations,whether it be limited number of sprays or the product causing burning and nasal irritation. This product lasts a reasonable amount of time and causes no discomfort. They also have a very comprehensive set of tests they've shared that support it's effectiveness in protecting against airborne threats. In general, I strongly recommend this product to keep yourself protected in public spaces where wearing a mask is not possible or desirable. Very good product and very good price!
