Vitamin D and Covid-19

Benefits are possible but evidence is sparse, indirect, and inconclusive

The covid-19 pandemic has led to many unfounded and exaggerated claims about possible treatments. One high profile controversy has been the role of vitamin D in the prevention and management of covid-19,12 so the National Institute for Health and Care Excellence (NICE), Public Health England, and the Scientific Advisory Committee on Nutrition rapid guideline is timely.3

The joint guidance concludes that there is little good evidence on vitamin D and covid-19, highlights the need for further research, and supports existing government advice that adults and children in the UK should take 10 μg (400 IU) a day between October and March, to optimise musculoskeletal health. It also recommends that certain populations such as minority ethnic groups, consider taking vitamin D throughout the year.
