Why do we need vitamin D?
imagesVitamin D is essential for healthy bones. In the UK we get most of our vitamin D from sunlight exposure from around late March/early April to the end of September.
We need vitamin D to help the body absorb calcium and phosphate from our diet.
These minerals are important for healthy bones, teeth and muscles.
A lack of vitamin D, known as vitamin D deficiency, can cause bones to become soft and weak, which can lead to bone deformities.
In children, for example, a lack of vitamin D can lead to rickets . In adults, it can lead to osteomalacia, which causes bone pain and tenderness.
Good sources of vitamin D:-
From about late March/early April to the end of September, most people should be able to make all the vitamin D they need from sunlight.
The body creates vitamin D from direct sunlight on the skin when outdoors.
But between October and early March we do not make enough vitamin D from sunlight.
Vitamin D is also found in a small number of foods.
oily fish – such as salmon, sardines, herring and mackerel
fortified foods – such as some fat spreads and breakfast cereals
Another source of vitamin D is dietary supplements.
