Why is vitamin D being researched during the COVID-19 pandemic?

A few reports have been published which investigate whether vitamin D levels might be related to COVID-19 risk. NICE, together with Public Health England (PHE), have reviewed these reports. They concluded that there is currently not enough evidence to prove whether vitamin D affects the body’s response to COVID-19. 

There are ongoing trials looking at vitamin D and COVID-19 at the moment. NICE and PHE will continue to monitor the research and update their advice with the results.

Many people will be spending more time indoors due to COVID-19, for example, because of lockdown restrictions or working from home. This may mean that vitamin D levels are lower than usual because they have had less sun exposure than normal. It is therefore even more important to make sure that you take a vitamin D supplement to protect against deficiency.
