What is the role of vitamin D?
- Vitamin D plays many roles in the body. One of the most important of these is to enable the absorption of calcium and phosphorus and maintain adequate concentrations of these minerals in the blood. Both calcium and phosphorus are involved in a number of essential processes that occur inside our cells. Vitamin D also promotes the laying down of minerals in bone (bone mineralisation) and supports the function of nerves and muscles.
- Vitamin D is especially important to infants and young children because it is needed in the development of strong and healthy bones and teeth.
- It is extremely important to ensure a sufficient intake of vitamin D and calcium during childhood and adolescence as this is when bones grow, lay down minerals and solidify. Good bone mineralization in childhood and adolescence determines how strong bones are in later life.
- Vitamin D is also important for the functioning of the immune system.
