Vitamin D, COVID-19 and influenza – supplements could prevent infection and death.

As the world grapples with the COVID-19 epidemic, and influenza continues to take a heavy toll, researchers are looking at ways of reducing the risk of infection and death. One treatment that seems promising is supplementation of vitamin D. Evidence supporting vitamin D can be found in multiple studies around the world.

A new research paper from scientists in the USA and Hungary looked at previous research into vitamin D. They found evidence that vitamin D may reduce infection and death rates in both COVID-19 and influenza.

This evidence includes that the COVID-19 outbreak began in winter, when vitamin D levels are at their lowest. In the southern hemisphere at the end of summer, infection rates were comparatively low.

Further supporting the case for vitamin D supplementation, it has been found that vitamin D deficiency contributes to acute respiratory distress syndrome.

Fatality rates for COVID-19 and influenza also increase with age and in people with chronic diseases, both of which are associated with higher rates of vitamin D deficiency.

The paper’s authors recommend supplementing vitamin D as a preventive measure, and suggest that higher levels of supplementation might be useful in treating people infected with the coronavirus.
