Nutrition During Pregnancy

Vitamin D

During pregnancy, Vitamin D is important for your bone health and your baby’s bone and tooth development. (1)  Vitamin D deficiency is more common in those living in northern latitudes, or if you have darkly pigmented skin.  Sunscreen use can also decrease the absorption of Vitamin D from the skin. (2)  Following a vegetarian diet can also put you at risk for Vitamin D deficiency. (3)

In 2010 the Food and Nutrition Board at the Institute of Medicine of the National Academies recommended pregnant and lactating women get 600 IU Vitamin D per day. (3)  Most prenatal vitamins contain 400 IU Vitamin D.

During pregnancy discuss with your healthcare provider whether to have your Vitamin D level checked to determine if you need additional Vitamin D in your diet or from supplements. (2)(3)(4)
