Vitamin D plays a number of crucial roles in the body including providing support for immune health, muscle health and strong bones and teeth. Vitamin D can be obtained through food sources such as eggs, fortified cereals and oily fish, but is predominantly synthesised in the skin through exposure to sunlight - hence why it is often referred to as the 'sunshine vitamin'.
Most healthy adults should theoretically be able to get enough Vitamin D from being outside in the sunshine, however Vitamin D deficiency is very common throughout the UK. This is as a result of a low level of exposure to sunlight, making Vitamin D synthesis almost impossible during the winter.
