Vitamin D deficiency as a corona risk – Artificial intake attenuates covid-19 progression.

Vitamin D can apparently curb severe corona after all. This is now recognized by the Federal Institute for Risk Assessment.

Frankfurt/Berlin – The question of whether vitamin D is useful for the prevention or treatment of covid-19 is currently undergoing a turnaround. For now the Federal Institute for Risk Assessment has announced that there are indications that “an insufficient vitamin D serum level is associated with an increased risk of acute respiratory infections.” Previously, the agency said there was no link between corona infections, covid 19 courses and vitamin D deficiency. That the prohormone may be a determining factor had already been suggested by a study from the University of Cantabria in Santander and a study from the University of Hohenheim.

“Some observational studies and intervention studies indicate that taking vitamin D supplements may have a positive effect on the course of covid-19 disease,” the BfR now also emphasizes. This is a finding that was hardly heard in Germany during the Corona pandemic – but not in Ireland. There, experts have been recommending the use of vitamin D supplements to prevent severe covid 19 for some time. The “Joint Committee on Health” assumes that a daily intake significantly reduces the risk of “respiratory diseases,” especially respiratory diseases. Unlike the BfR, the experts assume a causal relationship.

Covid-19: Vitamin D deficiency as a corona risk – experts warn

The Federal Institute, on the other hand, refers to the “uncertain data situation” in this context. Further studies on vitamin D and its influence on the course of Covid-19 are necessary. Nevertheless, the BfR makes a recommendation that is, however, of a general nature: “The use of dietary supplements may be useful, especially for people who belong to a risk group for an insufficient vitamin D supply.” This is specified in reference to the elderly, who are considered a risk group for corona infections: In old age, vitamin D formation decreases significantly, it says: “For this risk group, general supplementation with vitamin D up to 20 micrograms per day should therefore be considered,” the Federal Institute therefore recommends.

A general recommendation for the intake of vitamin D preparations for the prevention of a Sars-CoV-2-infection or a severe course of a Covid-19 disease remains out. This is currently not justifiable, says the BfR. A trend reversal, therefore, not a turnaround – and that, although the study situation is better than described by the BfR. For example, the expert group “COVRIIN”, which consists of infectiologists, emergency physicians and intensive care physicians and is an advisor to the Robert Koch Institute, stated: “A deficient vitamin D balance is associated with an increased risk of infection. A higher risk of severe courses could also be associated with vitamin D deficiency, among other factors.”

Coronavirus: RKI study attests to vitamin D deficiency in German population

The RKI itself also said in a study that around 82 percent of the population in Germany did not have an adequate vitamin D supply in winter. In spring, it is 73 percent, the institute said. Therefore, the scientists recommend, “Those who want to supplement vitamin D should resort to dietary supplements with up to 20 micrograms of vitamin D […] per day, since this dose is not associated with effects that are harmful to health.”

Regardless of an artificial supply of vitamin D, which can harm the body in too large quantities, experts recommend eating fish such as salmon or herring two to three times a week and exercising in the fresh air. Because there the “sun vitamin” store can still be filled best.
