Quercetin is a safe natural anti-oxidant and anti-inflammatory polyphenolic compound that found in various natural sources include onion, red grapes, honey and citrus fruits. It was shown that quercetin has the ability to chelate zinc ions and act as zinc ionophore.
I have been taking Honey and Zinc with my multi-vitamin for the past 7 months. I ever wore a mask and when my wife got the covit/FLU I did not.
How much honey and zinc have you been taking everyday?
One tablespoon of honey and 50mg of zinc
Make sure to get 2-3mg of copper a day too, zinc can cause copper deficiency.
