Low vitamin D level, higher corona risk? Expert gives new recommendation

Vitamin D strengthens our immune system and is vital for the body.

The “sun hormone” also seems to play an important role with regard to Covid-19.

• The human body produces

  vitamin D

  independently by converting the sun's rays through the skin.

  But foods such as tuna also contain vitamin D - but humans only cover a small part of their vitamin D requirements through food.

• Vitamin D

  is important

  for many metabolic processes in the body, above all it ensures that calcium can be well absorbed from food and built into the bones, thus reducing the risk of osteoporosis *.

• Low vitamin D levels were measured

  not only in osteoporosis patients, but

  also in Covid 19 patients

  : Professor Martin Smollich, a specialist pharmacist for clinical pharmacy, gives an assessment of the causes behind this.

: A lack of vitamin D in the body can promote infections, which is why a vitamin D deficiency should be treated.

What role does vitamin D play with regard to coronavirus infection?

Experts disagree.

But first studies show:

.

The big catch with the study situation, however, is that the majority of the clinical data is practically meaningless, "because either it was not adjusted for potential confounding factors or the vitamin D level was recorded for the first time at the time of hospital admission", quoted the Deutsche Apotheker Zeitung DAZ) Professor Martin Smollich, specialist pharmacist for clinical pharmacy and head of the pharmaconutrition working group at the Institute for Nutritional Medicine at the University Medical Center Schleswig-Holstein.

Smollich assumes a so-called reverse causality: Vitamin D deficiency as a consequence of Covid-19 and not as a cause.

A vitamin D deficiency occurred above average in diseases and living conditions that increase the risk of Covid 19 infection, such as old age, obesity or diabetes.

According to Smollich, prophylactic intake of vitamin D is basically not harmful, but he warns against too high a dosage.

Indications have shown that an

Protect yourself from coronavirus infection - with copper tape

Use the antiviral and antibacterial effects of copper in your own four walls.

But it's not that simple after all: with age, vitamin D production decreases and the individual metabolism, which varies greatly, does not allow for standardized recommendations.

But it has been scientifically proven that vitamin D is involved in innumerable processes in the body.

Does vitamin D deficiency favor severe Covid-19 diseases?

“There is ample evidence that various non-communicable diseases (high blood pressure, diabetes, cardiovascular disease, metabolic syndrome) are associated with low

plasma levels.

These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe

events, "summarizes the portal dw.de.

Too many factors were also not taken into account in the observational study by the University of Hohenheim, such as the lifestyle of the people, smoking and eating habits, job or hobbies (someone who likes to be out in the mountains usually has a much higher vitamin D-Spiegel as a serial junkie).

According to the study by the University of Hohenheim, if a

This cannot have negative effects, but a positive effect has not (yet) been proven.

"There are studies going on to check whether vitamin D helps with a Covid 19 infection, but I personally do not believe that this is really the case," dw.de quotes the endocrinologist Fassnacht.

However, this does not rule out the fact that there are people who benefit from supplementation.

: “My belief that the vitamin helps somewhere is very low.

But of course I can be wrong. ”
