Does vitamin D deficiency mean an increased risk of death from infection with the coronavirus?
Sunlight is important for the body’s own vitamin D production
Scientists have apparently found a link between vitamin D and the COVID-19 death rate. A team of researchers from the Queen Elizabeth Hospital in Norfolk, England, and the University of East Anglia examined the average vitamin D level in 20 European countries and compared it with the local coronavirus infection rate and mortality. And indeed: in the countries where the population has a comparatively low vitamin D level (e.g. Spain, Switzerland, and Italy), the number of COVID 19 cases and deaths was highest. (Southern Europeans avoid ultraviolet radiation more than Northern Europeans and also have more pigmented skin)
One came to a similar conclusion Case study carried out by a team of Indonesian researchers. They examined the data and disease courses of a total of 780 corona patients who had to be hospitalized due to the severe course of the disease. About half of the cases (49.7 percent) were adequately supplied with vitamin D – 4 percent of these cases died. Just over a quarter (27 percent of cases) had low vitamin D levels, of which 88 percent died. Of the 23 percent with acute vitamin D deficiency, 99 percent died. The researchers gave a value of over 30 nanograms per milliliter (ng/ml) as a yardstick for a “normal” vitamin D level. However, whether vitamin D supplementation can protect against the coronavirus has yet to be investigated.
Where is vitamin D in?
Vitamin D can be fed through food. Foods that contain the vitamin include, for example, high-fat fish such as salmon or cod, porcini mushrooms, butter, eggs, milk, and oatmeal. However, 80 to 90 percent of the vitamin D requirement is already covered by sunlight, which the body can use to produce the vitamin itself.
