Quercetin, EGCG, Hydroxychloroquine and Zinc: Can They Help Against COVID-19 virus?
Quercetin, Hydroxychloroquine, EGCG and Zinc are among the handful of COVID-19 treatments that are being studied as potential candidates that might influence the outcome in the prevention and management of COVID-19. Hydroxychloroquine, Quercetin and EGCG (EpiGalloCatechin Gallate) are all zinc ionophores. Meaning they all transport zinc into the cells. We will dive deeper into the science for each of the above treatment and supplement. Quercetin and COVID-19 Quercetin was initially found to provide broad-spectrum protection against SARS coronavirus in the aftermath of the SARS epidemic that broke out across 26 countries in 2003. Now, some doctors are advocating its use against SARS-CoV-2, in combination with vitamin C, noting that the two have synergistic effects. Quercetin acts as a zinc ionophore ( PubMed 2014), the same mechanism of action that hydroxychloroquine has via helping zinc pass the cell wall where it might halt viral replication. This zinc ionophore activity of querce
