According to the website ResearchGate.net: "Several studies have reported that zinc has a broad-spectrum antiviral activity against a variety of viruses. Increased intracellular Zinc concentrations inhibit RNA-dependent RNA polymerases and other proteins essential for the completion of different phases of the virus life cycle. Further, zinc also helps to maintain robust immune responses by producing cytokine and by modulation of immune cell activity."<ref>[https://www.researchgate.net/post/Is_a_combo_of_chloroquine_and_Zinc_a_cure_for_coronavirus Is a combo of chloroquine and Zinc a cure for coronavirus?]</ref>
