Frightened of common cold symptoms--next morning to symptoms!! Two times--two weeks apart!!
I had heard of quercetin and separately had heard of zinc but never heard of this product. I learned of this on a deal of the day. Purchased it for safekeeping because of COVID reviews. Woke up one day with wet head cold symptoms. In desperation I took one. The next A.M. woke up with NO common cold symptoms--no sneezing, no nose running, no "wet head" feeling. I was amazed. Again, two weeks later same thing happened. Start of bad head cold symptoms, took 1 and symptoms again gone!!
