This does prevent colds if taken at first sign. We also take after being around crowds or questionable people since covid. Wife and I have not had Covid but we are also fully vaccinated and are not sure this has made a difference but we think it has.

I used to get bronchitis every year as a result of a cold and had to take antibiotics for it. I've been using Zicam per the label for about 12 years now and have not needed antibiotics once. The cold runs its course, but I'm spared the dr. visit and meds. I always have it on hand.

Zicam is like magic. It works for me every time. I take it when I feel onset of sore throat. Now all my friends and family members are also convinced about this product. Good value. I wish Sams club has this product in stock in the stores. But I'm glad it is available online on Samsclub.com. As a plus member, I am happy with fast and free shipping.

This product is good for when you have a cold coming on. I highly recommend this product.

Work for me. Definitely help shorten the length and severity of colds if started early and taken regularly.

How do you know that it really shortens a cold? But if it gives the immune system a little boost, it is worth a try. I figure it can't hurt.

always helps not to have a bad cold symptoms!!!

Both items came on time and were as advertised.

This stuff stops a cold in it's tracks!

Awesome price for good prices fast shipping
