What is Vitamin D?
Vitamin D is important because it helps our bodies use calcium to build and maintain strong bones and teeth. Children (and adults) in Ireland have low levels of vitamin D which can lead to weak bones. In severe cases low levels of vitamin D can cause rickets(1) in children. There has been an increase in the number of cases of rickets in Ireland in recent years.
