Prenatal vs Regular Multivitamin: What Differs

Where a prenatal label and a regular label can matter

Compare these on the Supplement Facts panel, which must list each ingredient in the product. [4]

• Vitamin A. The NHS says not to take cod liver oil or supplements containing vitamin A (retinol) in pregnancy, because too much can harm the baby's development. [2] It also notes that many multivitamins contain vitamin A. [5] So a regular multivitamin is not automatically suitable in pregnancy. Check the vitamin A form and amount with your midwife or pharmacist.
• Iron. The NHS says iron levels are checked at routine blood tests in pregnancy, and a GP or midwife recommends iron supplements if levels are low. [2] Iron is not something to add on a guess.
• Folic acid. Compare the amount on the label with the advice your care team gave you, not with the figures in the table above.
• Other ingredients such as iodine, choline and DHA: see prenatal vitamin contents. We did not read an official body that sets the same required list for every prenatal product.

Prenatal instead of a regular multivitamin?

The USPSTF statement on multivitamins and disease prevention was written for nonpregnant adults and "does not apply to... persons who are pregnant or may become pregnant." [3] Whether a person who is not pregnant should use a prenatal-labeled product is a question for a clinician. The NHS says taking 17 mg or less of iron supplements a day is unlikely to cause harm, but also that very high doses can be fatal, particularly for children.

No universal winner

For pregnancy, the question is whether the specific product matches what your care team advised. Read more in prenatal and postnatal vitamins and the pregnancy and breastfeeding safety page.
