Millions of Britons should be encouraged to take Vitamin D supplements in winter as this could help fight the coronavirus according to a report commissioned by the chief scientific adviser.
More than 1 in 5 people living in the UK do not have enough in their bodies. The normal source of Vitamin D is via the sun’s rays on exposed skin. The elderly and people isolating inside will have very low levels.
It appears that low levels may contribute to susceptibility to Covid 19. Given the protective effects of Vitamin D against all respiratory tract infections it makes good sense to take it routinely in winter or for anyone who does not go in the sunshine.
Vitamin D deficiency in the UK at 22% is higher than most other European countries. Nordic countries fortify their flour and bread with Vitamin D. In the USA it has been added to milk for years.
How can I get enough Vitamin D?
It is vital for a healthy immune system. People usually make it in summer from sunlight on the skin. However this takes longer those with darker skins. In winter your Vitamin D needs to come from your diet such as eggs, mushrooms and oily fish, but it is hard to eat enough to make up there required dose.
It is therefore essential that most people take supplements. This is even more important for anyone elderly, in care homes, anyone wearing clothes that cover most of the skin and anyone with dark skin.
Dosage
The NHS suggests that everyone takes 10 mg pre day.
