More Studies Shed Light on the Value of Zinc in Covid-19
Evidence suggests that zinc could protect against Covid-19 — how?
Evidence is growing that shows nutritional status plays a part in how Covid-19 would turn out — whether a person recovers or progresses into a more severe condition. For example, many human studies back the anti-Covid-19 effects of vitamin D, including a randomized controlled trial (RCT). Notably, the second most important nutrient next to vitamin D that could fight Covid-19 is perhaps zinc — why and how?
Zinc as an antiviral and immunomodulator
Zinc has long been known to be an enemy of viruses. Zinc could block the replication of coronaviruses by disrupting its enzyme that makes its genes. For instance, there was an over 50% reduction in SARS-1 replication in cells with healthy zinc levels.
And the antiviral spectrum of zinc is broad, including herpes simplex virus, hepatitis virus, human papillomavirus, respiratory syncytial virus, rhinovirus, HIV, and many more. Many studies have also supported the efficacy of zinc therapy against both upper and lower respiratory tract infections, as compiled by a 2020 research review.
Another review, published in 2020, ranked zinc as the top three most vital nutrients for…
