Dr Z recommends Quercetin for those who may not have access to HCQ.
It’s a natural flavonoid, that’s been around for years, in supplement form.
It does the same thing, for zinc, that HCQ does, per Dr Z.
What about Quinine? Could it be used in place of Quercetin?
Be sure to purchase quercetin combined with bromelain, or separately, for better absorption.
