There is something new under the sun: Vitamin D may reduce the risk of infection and hospitalization


The sun is smarter than ever: A new Israeli study, jointly with Leumit Health Services and Bar-Ilan University, found that those with vitamin D deficiency were 1.45 times more likely to be infected with Corona and twice as likely to be hospitalized, compared to those with normal vitamin D levels.

The study findings support that vitamin D deficiency was an independent risk factor for coronary heart disease and hospitalization. This, too, by neutralizing other variables such as age and background diseases. The study examined all Leumit policyholders who performed a pen test in March and April (in the first wave), and for whom there was a record of vitamin D levels.

A total of 7,807 people were tested, of whom 782 (10.1%) were diagnosed as positive for Corona. The study found that among infected patients, the average level of vitamin D in the blood was significantly lower than in those who were not infected. The full study was published in the scientific journal “FEBS”.

“It was found that in the group of positive patients for the virus with low levels of vitamin D in the blood, there was a higher chance of more serious illness and the need for hospitalization,” explains Dr. Yevgeny Marzon, director of the Department of Managed Medicine at Leumit Health Services, adding: Another significant risk of serious illness. ”

Dr. Marzon emphasizes that “My recommendation, especially for older people, is to take vitamin D supplementation. According to our study, there is a chance that high levels of vitamin D are a protective factor from corona and its complications. “The study we conducted is the largest of its kind so far in this area, but it was not an interventional study, and it is still not possible to establish a causal link between the administration of vitamin D and the prevention of infection with the corona virus.”

Beyond that, the study came up with another interesting finding. “Surprisingly, chronic conditions such as dementia, cardiovascular disease and chronic lung disease, which were considered risk factors in previous studies, were not found in our study as a factor that increases the rate of infection,” says Prof. Shlomo Winker, head of the National Health Services Division. It has to do with adherence to guidelines among chronic patients. “

Vitamin D is important for bone health and its deficiency is linked to osteoporosis, but there are also speculations that the vitamin improves the immune system. There is scientific evidence for the contribution of vitamin D to reducing the risk of acute respiratory infections.
