Is it safe to take calcium and vitamin d during pregnancy?

Yes: Building healthy bones & teeth. While your bones provide an abundant supply of calcium for your developing baby, you can insure you're not depleted of this vital mineral by taking 1500mg of calcium and 400 units of vitamin d daily while pregnant and breastfeeding too. While many prenatal vitamins contain the later, they often don't have enough calcium. Dairy products or a supplement will suffice.

Yes: It is not only safe, it is essential, unless your dietary intake meets your provider's recommendations.
