Is vitamin D the new ally against the wave of Covid-19 sweeping the world? Perhaps according to the conclusions of a study conducted by researchers at Trinity College Dublin (Ireland). According to this new research (source 1), vitamin D allows the body to protect against severe forms of Covid-19. These findings were published in the journal Scientific Reports.
According to Irish researchers, the vitamin D provided by solar radiation could prevent severe forms of the virus. Indeed, the researchers analyzed the link between the level of solar radiation of the place of residence of the patients the weeks before the infection and the reduction of the risk of developing a severe form. “Our study adds further evidence that vitamin D may protect against serious infection. It is essential to conduct a Covid-19 trial properly designed on vitamin D supplementation, “said Lina Zgaga, the study’s principal investigator at Trinity College in Dublin.
As the National Food Safety Agency (ANSES) reminds us, (source 2) sufficient exposure to sunlight makes it possible to maintain a supply of vitamin D in the body. For this, it is recommended to expose yourself to the sun for 15 to 20 minutes at the end of the morning or in the afternoon. In May 2020, the Academy of Medicine (source 3) expressed itself on a possible correlation between vitamin D and Covid-19. He was then mentioned “a significant correlation between low serum vitamin D levels and mortality from Covid-19 “.
Before adding: “This phenomenon generally follows a North-South gradient, although there are exceptions such as the Nordic countries where the supplementation of vitamin D nutrients, in particular milk products, is systematic. On the other hand, the countries from southern Europe surprisingly a high prevalence of vitamin D deficiency despite higher sunshine. This would explain that infants who receive vitamin D regularly have asymptomatic forms of Covid-19 and fewer complications “.
In view of these conclusions, the experts from the Academy of Medicine had also recommended vitamin D supplementation 800 to 1000 IU / day in people under the age of 60 upon confirmation of the diagnosis of Covid-19.
