Dietary intake of vitamin D is not enough.

The National Diet and Nutrition Survey (Bates et al 2011) show adult females have low levels of vitamin D. Many women in midwives' care may be vitamin D deficient. The aim of this article is to update midwives' knowledge of vitamin D in line with their statutory role as a midwife, so they can recognise deficiency and make women aware of the consequences for themselves and their baby.
