Another study determines Vitamin D could lessen the severity of Covid-19 infections.

  • A new publication from School of Medicine, in collaboration with the University of Liverpool, highlights the association between vitamin D levels and mortality from COVID-19.
  • Vitamin D is produced in the skin from UVB sunlight exposure.
  • This study shows that, counter intuitively, countries at lower latitude and typically sunny countries, such as Spain and Northern Italy, have high rates of vitamin D deficiency.  These countries also experienced the highest infection and death rates in Europe.
  • The northern latitude countries of Norway, Finland and Sweden, have higher vitamin D levels despite less UVB sunlight exposure, because supplementation and fortification of foods is more common. These countries have lower COVID-19 infection and death rates.
  • This impact of the vitamin on Covid-19 may be because vitamin D is important in regulation and suppression of the inflammatory cytokine response, which causes the severe consequences from the virus.
