More evidence has emerged which suggests COVID-19 patients with high vitamin D levels are more likely to survive the disease.  

A study from the US found patients with a severe deficiency are twice as likely to experience major complications and die. 

Researchers led by Northwestern University say the observational evidence is still preliminary and caution against raiding the supplement aisles. 

They call for more research to understand what causes this connection between vitamin D and coronavirus mortality. 

 

Vitamin D can make its way into the human body either through certain foods, such as fish and mushrooms, or can be produced by skin cells when exposed to sunlight. The NHS says adults should have around 10 micrograms of vitamin D every day.

This finding backs up separate studies which also found low levels of vitamin D may make it more likely an individual will die after contracting coronavirus and that it also helps a person recover after contracting the coronavirus. 

A study from Vrije Universiteit Amsterdam found countries with low vitamin D levels were also the countries with highest mortality and COVID-19 infection rates.

This has been echoed by the latest research from the US. 

A ten-week trial from the University of Granada is also currently ongoing after a recent study by Trinity College Dublin found adults who took Vitamin D supplements saw a 50 per cent fall in chest infections.

Researchers crunched the coronavirus statistics from various countries that experienced severe outbreaks of COVID-19. 

It included data from hospitals and clinics in China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the UK and the United States. 

The research has been published online at medRxiv and has not yet been peer-reviewed, the process in which independent researchers scrutinise the study. 

The research was led Vadim Backman, a professor of Biomedical Engineering at Northwestern University, who said the study found vitamin could cut mortality rates in half.  

He added that having high levels of vitamin D will not stop someone catching the virus, but may be able to reduce complications and prevent death.   

When looking through the data the researchers noted an erratic pattern between infections and deaths and endeavoured to understand what, if anything, connected them. 

They looked at differences in healthcare quality, population, ages, prevalence of testing and different COVID-19 strains but did not find any significant connection.
