Can Zinc Prevent COVID-19?

New takes from COVID-19 conference

Part Three



In a talk titled ‘Nutrition, immune function and COVID-19’, Prof Philip Calder, University of Southampton, explained that a well-functioning immune system is key to providing robust defense against infections such as COVID-19. Amongst the many nutrients that are needed for immunity, he highlighted vitamin D, zinc and selenium as being particularly important for anti-viral immunity.

Calder emphasized the various roles of zinc in the immune system, particularly its specific function of preventing multiplication of single-strand RNA viruses, like the Coronavirus, by inhibiting enzymes they need to spread. He explained that diet can provide sufficient zinc without the need for supplements; meat, poultry, cheese, shellfish, nuts, seeds and wholegrains are all sources of zinc.
