Advisory statement on likely place in therapy
There is no evidence to support taking vitamin D supplements to specifically prevent or treat COVID‑19. However, all people should continue to follow UK Government advice on daily vitamin D supplementation to maintain bone and muscle health during the COVID‑19 pandemic.
To protect bone and muscle health, the UK Government advises that everyone needs vitamin D equivalent to an average daily intake of 10 micrograms (400 international units). They advise that all people should consider taking a daily supplement containing 10 micrograms vitamin D during autumn and winter months. They also advise that people whose skin has little to no exposure to sunlight and ethnic minority groups with dark skin, from African, Afro-Caribbean and South Asian backgrounds, should consider taking a vitamin D supplement all year round. This advice would also apply to people whose skin has little to no exposure to sunlight because they are indoors shielding or self-isolating. Therefore, UK Government advice during the COVID‑19 pandemic is that everyone should consider taking 10 micrograms of vitamin D a day because they might not be getting enough from sunlight if they're indoors most of the day. See also NICE guidance on Vitamin D: supplement use in specific population groups.
Following appropriate testing and clinical management, people with vitamin D deficiency may also be prescribed higher therapeutic doses of vitamin D.
