Public Health England has updated its official advice on vitamin D supplements in light of the Covid-19 lockdown restrictions requiring people to stay in their homes as much as possible. 

In a 'coronavirus update,' PHE advised the public:

• Consider taking 10 micrograms of vitamin D a day to keep your bones and muscles healthy. 
• This is because you may not be getting enough vitamin D from sunlight if you are indoors most of the day. 
• There have been some news reports about vitamin D reducing the risk of coronavirus. However, there is no evidence this is the case. 
• Do not buy more vitamin D than you need. 

Graham Keen, executive director of the Health Food Manufacturers' Association, said: “While vitamin D supplementation has long been recommended for key population groups, this broadened advice is welcome to help everyone maintain healthy joints and muscles.”
