“In particular, these diseases are often associated with vitamin D deficiency.
This has implications for COVID-19, ”said Professor Hans-Konrad Besalski of the University of Hohenheim.
In a study by a Spanish study group, 80 percent of COVID patients surveyed were vitamin D deficient.
Nutritionists at the University of Hohenheim suspect that vitamin D deficiency may worsen COVID-19.
For review, they reviewed 30 studies with a total of 53.
000 patients with COVID-19 and from this conclude that vitamin D deficiency can affect the severity and mortality from COVID-19.
Especially when patients are in any case at risk due to major diseases such as high blood pressure, diabetes, heart disease or obesity.
For the doctor’s professor
Peter Stelle of the Institute of Food and Nutritional Sciences at the University of Bonn, Hogenheimer’s research is not surprising.
“Malnutrition is detrimental to viral diseases, whether flu or COVID,” he says.
Besalsky points to the crucial role of the vitamin for the immune system: it regulates it, and in the case of infection, the likelihood of inflammatory processes in the body increases without sufficient intake.
The sun vitamin cannot cure the disease under any circumstances.
However, in general, the current state of research on COVID-19 and vitamin D is too subtle to make any further statements.
“There are no scientific studies that prove a positive effect of vitamin D on the course of COVID-19,” says Professor Helmut Shatz, a specialist in vitamin D of the German Society of Endocrinology.
The status of vitamins and trace elements should usually be checked in people with severe viral diseases.
“If there are not enough vitamins and minerals, the body has more problems with the implementation of healing processes.

“There are several association studies that show that vitamin D levels are low in people with COVID-19.
However, this does not prove causality, “Shatz said.
“To do this, you need randomized, placebo-controlled studies in which, according to popular science, you are promising to give vitamin D and a fictitious drug, placebo, and watch what happens.
The idea, which is widely spread on social media, that vitamin D income can reduce the risk of serious COVID 19 has not been scientifically proven.
“The study of the University of the High House is a review of the literature.
It conducted 30 examinations and concluded: When analyzing patients with COVID-19, vitamin D levels are often low.
But this does not mean that people who are healthy and have low levels of vitamin D have a higher risk of developing COVID-19, ”explains Stele.
However, severe vitamin D deficiency can adversely affect the immune system.
Therefore, previously ill and elderly people should talk to their doctor about this topic.
Especially for people in nursing homes, it is advisable to check the level of vitamin D for a long time.

Even those who have typical but nonspecific symptoms of deficiency, such as frequent infections, body aches, or hair loss, can resolve this issue during a practice visit.
Deficiency can occur especially quickly in winter, because the vitamin is formed by the body under the action of sunlight.
If determining the level of vitamin D makes sense from a medical point of view, a blood sample is taken.
Serum is tested in the laboratory for so-called 25-hydroxyvitamin D.
If the doctor prescribes the test medically necessary, the costs will be covered by the state health insurance companies.
If a laboratory test shows a vitamin D deficiency, your doctor will decide what to do.
For example, he may prescribe vitamin D supplements in the appropriate dosage.
According to DGE and BfR, “sun vitamin” is insufficient at less than 30 nanomoles per liter of serum (30 nmol / l).
A severe deficiency occurs at 20 nmol / L.
A blood concentration of at least 50 nanomoles per liter of serum is considered beneficial for bone health.
If this amount is not achieved due to the body’s own production of vitamin D, an adequate supply of vitamin D is provided …
