Indeed, zinc protects against corona
Yesterday we wrote about a 2020 study from India, in which a good zinc status improved the prospects of people with a corona infection. In 2021, Spanish researchers published a similar study, confirming the findings from India in detail.
A healthy zinc level is somewhere between 70 and 110, we read on the Mayo Clinic website. About half of the study participants had a zinc level below this range.
The patients with abnormally low zinc levels of less than 50 micrograms of zinc were hospitalized for 25 days. In this group, 21 percent died.
The study participants with a zinc status of over 50 stayed in the hospital for only 8 days. In this group 'only' 5 percent of the study participants died.
When the researchers smoothed out the effect of other factors as best they could, they were able to calculate that an adequate zinc status reduced the risk of death from corona by a factor of 3.2.
The researchers found that an adequate zinc status reduces the production of proteins that stimulate inflammatory reactions, such as CRP and Interleukin-6.
But that's not the whole story. When the researchers in their lab released the coronavirus on kidney cells in a test tube, they saw that the virus could not multiply as well as the cells contained more zinc.
"It should be also recommended to promote zinc supplementation programs targeted to people at risk of zinc deficiency, such as the elderly, in order to reduce COVID-19's severity."
