Vitamin D protects against the coronavirus. Confirmation in an American study

We return to talk about vitamin D and the possible beneficial effects of this substance against Covid-19. This is following the results of a new study which confirms its potential.

In recent months, there have been several studies that have analyzed the role of vitamin D as a protective factor against coronavirus. According to previous research, this substance would be able to reduce the severity of symptoms and the risk of mortality in case of contracting the virus.

But there was also an Italian study that went even further, even believing that this vitamin could have a therapeutic role against the disease.

To these is now added a study conducted in the United States and published in the scientific journal JAMA Open Network , which substantially confirms what others have hypothesized: vitamin D is able to protect against coronavirus.

To make this claim, scientists from the Department of Medicine and the Center for Health and Social Sciences of the University of Chicago (Illinois) , coordinated by Professor David O. Meltzer, analyzed the medical records of some patients.

There were about 489 people (mainly men with an average age of 49.2 years) whose vitamin D levels were known from the previous year compared to when they had undergone the Sars-coV2 swab (15% of the sample was then positive result).

The patients were divided into three main groups: probably vitamin D deficient; probably with adequate levels of vitamin D and uncertain. Thanks to statistical analyzes it was noted that the risk of coronavirus positivity was 1.77 times higher for the group probably deficient in vitamin D.

However, it is necessary to specify what the study meant by vitamin D deficiency. This was considered the condition of those patients whose analyzes revealed a concentration of 25-hydroxycholecalciferol lower than 20 ng / mL or 1,25-dihydroxycholecalciferol lower than 18 pg / mL .

Scientists further state that:

“Vitamin D treatment has been found to reduce the incidence of viral respiratory tract infections, especially in patients with vitamin D deficiency”

The conclusions of the study support the need for further randomized studies to confirm the positive influence of this substance on the new virus.
