What is vitamin D?

Vitamin D is a hormone that controls calcium levels in the blood. It is needed to develop and maintain healthy bones, muscles and teeth and is also important for general health.

Vitamin D occurs naturally in fish and eggs, while margarine and some types of milk have added vitamin D. However, diet only makes a small contribution (approximately 5–10%) to the body's overall vitamin D levels and it is therefore difficult to get enough from food alone.
