Profi Everyday Nasal Spray - Helps Defend Against Airborne Germs, Lasts Up to 8 Hours, Advanced Nasal Spray for Air Travel, Work, Conferences & Indoor Gatherings - 180 Sprays, 0.58 FL OZ

Used this on my first plane trip in years ... Was at 2 airports and around a lot of people, got hardly any sleep which usually doesn't bode well for health; but using this each day kept me well! It works phenomenally. I used it everyday and still have plenty left. The smell and taste are fine. It's very gentle and didn't make my throat burn as some do. Very easy to use, just remember to re-dose if you're out more than 8 hours.

Great product! Effective and gives me peace of mind when I have to work or travel in close quarters. Wish we had this in the Navy.

I am auto-immune compromised and wanted to try ProFi. I have been using it for a week now during peak cold and flu season. I haven’t gotten sick once! I am happy with my purchase; it helps me live a whole life, knowing I am protecting myself. Additionally I was pleased there wasn’t any lingering bad taste or smell like other nasal sprays I have tried. As someone who takes my health very seriously I am grateful to have found ProFi. While nothing works 100% I do feel it improves my odds and gives me more freedom.

Seems to be effective against colds and the flue, but hard to tell. I am told that using every day diminishes the effectiveness. I only used for social situations.

After reading the about the Harvard scientists that developed this product I tried it. A little bit of iodine smell but dissipates quickly. Easy to use and so far effective.

This stuff is amazing and totally worth the money. I work in a school with young children and have done so for the past 10 years. I changed careers later on life so I got sick many many times from the kids. I started taking Profi in September, and this is the first year that I haven’t missed at least 3 to 4 days sequentially due to illness. In fact, I’ve barely been sick at all this year and if I have, it was just a minor cough or sniffle, nothing that kept me out of work. Definitely try it!

A friend turned me on to Profi as something that worked in keeping her healthy and well. As someone who always gets sick (and then takes forever to get better...), Profi helped me get back out in the world, unmasked--even during cold and flu season! I've only been sick one time in a year and a half (!!!) of using Profi! It doesn't really have a taste or smell, which is great (although I do sneeze right after every application, no biggie). It's a bit pricey, but IMO, worth it. Both my husband and I have Profi on auto-subscribe, that's how much we love it.

My sister, who is immune compromised, is always looking for ways to protect herself. She was the person who initially turned me on to Profi. My 11 year old son seems to get sick often. He missed 21 days of school last year, and I knew as he transitioned to middle school, missing such large swaths of school would be unmanageable for him. He uses Profi spray everyday before school, and even here in MN where the flu/cold season is running rampant, he has not caught a single thing!! Not even a cold. We’re heading into mid January without a single missed day of school. This stuff works!! My kid is the walking proof. Just keep in mind it lasts 8 hours, so if you have evening plans, you need to redose.
