there's a peer-reviewed study on quercetin and zinc and apparently zinc when you take it is zinc has powerful antiviral properties to it but it's it's difficult for it to get in the cells
What the evidence says 01 / RECORD
A peer-reviewed study does exist showing that quercetin, like EGCG, acts as a zinc ionophore, meaning it can help transport zinc across cell membranes, and zinc itself has documented antiviral activity in laboratory settings by inhibiting viral RNA polymerase. However, that ionophore evidence comes from in-vitro (cell and liposome) experiments published in 2014, not a clinical trial, and it was not conducted in the context of COVID-19. Clinical evidence for quercetin (with or without zinc) against COVID-19 in humans is limited to small, open-label pilot trials, such as a 42-patient Italian study, that reported faster viral clearance and symptom improvement but were not blinded, placebo-controlled, or adequately powered to establish efficacy. A 2022 review in Phytotherapy Research concluded that despite plausible mechanisms and preliminary clinical signals, the hypothesis that quercetin plus zinc benefits COVID-19 treatment or prophylaxis has not been clinically tested, and larger high-powered randomized controlled trials are still needed to confirm quercetin's clinical benefit. As of the time of this claim, no robust clinical trial had demonstrated that quercetin plus zinc prevents or treats COVID-19 in humans, so the underlying cell-biology mechanism Rogan describes is real but the implied protective benefit remains unproven.
