• Except for iron, folic acid, and possibly calcium, a well-rounded diet should supply all the nutrients you need during your pregnancy. Very high levels of vitamin A have been linked with severe birth defects. Your prenatal multivitamin should contain no more than 5,000 IU of vitamin A. If you are already taking a multivitamin, let your doctor know.
  • If your prenatal vitamin makes you sick, try taking it at a different time of day, or with a meal. Try over-the-counter vitamins with at least 400 micrograms of folic acid in them. If you are still unable to tolerate the vitamins because of nausea, please let me know.
