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)
