NanoRush Pre-Cold Sublingual Spray - Immune System Defense Booster with Vitamin C and Zinc

I have purchased two of these pre cold shield bottles from amazon. I work with the public and i also fly a lot So far since I have taken the cold shields I have had no cold or flu. Every year I usually get it from a co worker or customer or someone couching without covering while flying on an airplane. Very happy with this purchase, just three pumps every morning under the tongue and I’m shielded—taste good too!

A bit pricy, but I don't get sick when I use it. I use some elderberry syrup as well anytime I feel something starting in my throat.

Tastes good but the spray will stop working after a few days.

I am hoping that it does what it says it does. However, I have now returned 3 bottles. There is plenty of liquid in the bottle, but it stops spraying. I can almost tell this is going to happen on the 1st try.

Zinc and Vitamin C have always worked wonders for me at the beginning of a cold or to prevent one if people around me were sick. When taken regularly and according to dosage instructions even after the symptoms subside for a couple days, my cold is almost always drastically shortened and not severe. This product was a great find. The ease of use, rapid absorption and decent flavor. Highly recommend for an immunity boost!

Nano Rush Pre Cold Shield is a phenomenal product. My husband works as a Teacher with elementary school children. He usually catches a cold in early September, when children return to school, but this year? Nothing!. I buy 2 spray bottles at a time. 1 for him, and 1 for me. We believe this formula is keeping us from getting sick. I love the taste!. It needs to be in everyone’s medicine cabinet!. It works!

I swear by this to ward off a cold. At the very first sign of feeling like I MIGHT be coming down with one, I spray this under my tongue, take 2 aspirin, and go to bed. The next morning the feeling is gone.

I bought this for a family member and they are very happy with it!
