On 28th November the government announced that clinically extremely vulnerable people will be offered free vitamin D supplements for the winter

This information is sourced from NICE (December 2020):

• Encourage people to follow UK government advice on taking a vitamin D               supplement to maintain bone and muscle health
• For most people, 10 micrograms (400 units) of vitamin D a day will be enough to prevent serum 25(OH)D concentration from falling below 25 nmol/litre
• Taking too high a dose of vitamin D over a long period of time could be harmful because it can cause hypercalcaemia
• Do not offer a vitamin D supplement to people solely to prevent Covid-19, except as part of a clinical trial
• Do not offer a vitamin D supplement to people solely to treat Covid-19, except as part of a clinical trial

This information is sourced from SAGE (October 2020):

• Further evidence is needed to assess whether a vitamin D deficiency will impact any seasonal effects of SARS-CoV-2
• There are some suggestions that those more likely to self-isolate, and vulnerable groups may have a higher incidence of vitamin D deficiency, potentially increasing the likelihood of adverse risks should they become infected

This information is sourced from NHS UK (August 2020):

• It’s important to take vitamin D as you may have been indoors more than usual this year
• You should take 10 micrograms (400 IU) of vitamin D a day between October and early March
• There is currently not enough evidence to support taking vitamin D to prevent or treat coronavirus

This information is sourced from the Center for Evidence-Based Medicine (CEBM) (May 2020):

• We found no clinical evidence that vitamin D supplements are beneficial in preventing or treating Covid-19
• There is some evidence that vitamin D may have a role in preventing other respiratory infections, particularly for people with low or very low vitamin D status
• People at risk of vitamin D deficiency should in any case take supplements in line   with current guidance
• Clinicians should continue to treat people with vitamin D deficiency
