Add vitamin D to bread and milk to help fight Covid, urge scientists ?

Scientists are calling for ministers to add vitamin D to common foods such as bread and milk to help the fight against Covid-19.

Up to half the UK population has a vitamin D deficiency, and government guidance that people should take supplements is not working, according to a group convened by Dr Gareth Davies, a medical physics researcher.

Abstract

Vitamin D deficiency, which impedes good immune function, is common during winter and spring in regions of high latitude. There is good evidence that vitamin D deficiency contributes to the seasonal increase of virus infections of the respiratory tract, from the common cold to influenza, and now possibly also COVID-19.
