Question
How should women during pregnancy take vitamin D to maintain their own and their newborn’s health?
Answer
Women during pregnancy should consume 1000 units of vitamin D daily to ensure that their blood level of 25-OH-D exceeds 50mol/L. If women have insufficient vitamin D at the time of delivery, their newborns may also be deficient in vitamin D and may present with related symptoms earlier. Therefore, it is recommended that pregnant women supplement enough vitamin D to ensure that their 25-OH-D concentration exceeds 80mol/L.
