A Zinc Ionophore

Quercetin is a zinc ionophore. It transports zinc ions into cells, where they "poison" various enzymes required for viral replication. With zinc available in the cytosol inside a cell, most viruses are terminated. The zinc attaches to the replication enzymes, bends them out of shape so that they can no longer catalyze various reactions required in viral synthesis.

But if the diet is zinc deficient, there won't be enough to get transported into cells by quercetin. My daily multivitamin provides 30 mgs. Some authorities say 15 to 18 mgs is sufficient.

Since taking 7000IU of vitamin D-3, along with 400mg of magnesium (threonate), along with the quercetin, for many years now, I've not had a single viral disease.
