If you or someone you care for is in a higher risk group they may need to take Vitamin D supplements.
You can take Vitamin D supplements as tablets, liquid or a spray, and they can be bought in a pharmacy.
Alternatively, you can increase your Vitamin D intake through your diet.
The NHS lists foods such as salmon, sardines, herring, mackerel and egg yolks as good sources of Vitamin D. Red meat, Liver and some breakfast cereals can also give you a boost of Vitamin D.
