Vitamin D, known as the ‘sunshine vitamin’ as we get most of our vitamin D from sunlight on our skin. Lots of people receive ample vitamin D from sunshine but for some of us, it can be sometimes be difficult to get.
We need vitamin D to help the body absorb calcium and phosphorus from our diet. These minerals are important for healthy bones and teeth. Even if you have a calcium-rich diet (for example from eating plenty of low fat dairy foods and green leafy vegetables), without enough vitamin D you cannot absorb the calcium into your bones and cells where it is needed.
