Lot of recent studies have concluded role of vitamin D and Covid-19 severity which may lead to mortality. Vitamin D may offer protection from viral infection and help reduce the symptoms of Covid-19.
Vitamin D plays an active role as an immunity booster in our immune system and its functioning. It regulates our white blood cells thus prevent them from releasing excessive inflammatory cytokines. This role of vitamin D could helpreduce severity of cytokine storm caused due to Covid-19. Vitamin D also helps protects our lung tissues from injury and acute respiratory tract infections risk is considerably reduced.
A recent vitamin D study indicates that among 20 European countries, there is a correlation between the levels of vitamin D and Covid-19 cases and mortality. It is found in older population levels of Vitamin D are very low in some of these countries, especially in Switzerland, Spain and Italy. Hence population there is more vulnerable to developing Covid-19. Scandinavian nations due to their eating habits and having rich vitamin D diet thus they have lower numbers of Covid-19 cases than rest of Europe.
