Before they took it off the market, I used the zinc nasal spray as soon as I felt the symptoms of my cold. It was very interesting. My cold still lasted a few days. But the sprays got rid of 90% of the symptoms! It was as if the cold wasn't there other than a bit of runny nose.I feel pretty certain after years of use that zinc lozenges, used correctly, really lessen the symptoms of a cold. I don't think it's placebo. I saw a study the British govt that confirmed same. Key is to catch it early, and for me, in two days the symptoms are largely gone.
Then I learned that it could have gotten rid of my sense of smell forever . Wish there was a safe way to still inhale them that way.
I have heard the other methods are nasty from taste point of view. Are they?
