Vitamin D

Vitamin D is a fat-soluble vitamin, which plays an essential role in many functions of the body including the regulation of phosphorus and maintaining the structure of bone and teeth, and normal immune function. It can help to reduce depression, aid weight loss and play a role in building and maintaining muscle. It is sometimes referred to as the ‘sunshine vitamin’ because it’s produced in our skin in response to sunlight. We also obtain it from foods such as oily fish, eggs, fortified fat spreads and some fortified breakfast cereals, but it’s difficult to get enough from food alone, as few foods provide it and often only in small amounts.
