Vitamin D helps to keep bones, teeth and muscles healthy. It also plays an important role in the immune system, which helps our body fight infection. However, the role that vitamin D plays in the management of COVID-19 is not completely clear currently. Clinical studies are ongoing to determine if vitamin D helps prevent respiratory complications, or whether it provides specific protection towards COVID-19. The emerging evidence suggests that the outcomes for those who develop COVID-19, and who already have a deficiency or insufficient levels of vitamin D, may be negatively affected in terms of morbidity (degree of ill health) and mortality (death rates).
The NHS across the UK advises anyone staying at home for most of the day, with limited exposure to sunlight, to consider taking a daily 10 microgram vitamin D supplement.
