In septentrional countries without vitamin D supplementation of milk and dairy products, many pregnant women are vitamin D deficient. Consequently vitamin D deficiency is present in many newborn infants, which may lead to neonatal hypocalcemia and vitamin D deficient rickets. A prevention of vitamin D deficiency is therefore a necessity in pregnant women through a vitamin D supplementation. This can be done either by a daily supplementation of 400 IU during all pregnancy, or a daily supplementation of 1,000 IU during the third trimester, or by giving a unique dose of 100,000 to 200,000 IU during the seventh month of pregnancy.
在未对牛奶和奶制品补充维生素D的北方国家，许多孕妇缺乏维生素D。因此，许多新生儿也存在维生素D缺乏的情况，这可能导致新生儿低钙血症和维生素D缺乏性佝偻病。所以，通过补充维生素D来预防孕妇维生素D缺乏是很有必要的。这可以通过在整个孕期每天补充400国际单位，或在孕晚期每天补充1000国际单位，或在怀孕第七个月一次性给予100000至200000国际单位的剂量来实现。
