Iron Iron can reduce the risk of iron-deficient anemia if indicated by your doctor, supporting healthy labor, birth, and iron levels in your baby.  Taking iron also supports healthy placenta development.(2,5)

Who Needs Prenatal Vitamins?

Looking at prenatal

Reproductive-age women who plan on getting pregnant generally need to take prenatal vitamins.(7) Starting them before conception can help protect your baby's health early. For example, a baby's brain and spine start developing in the first month of pregnancy, before you may know you're expecting.

You may need to take specific prenatal vitamins if you have a health condition or are on a special diet.(8) For example, if you are a vegetarian, you may need to take vitamin B12, zinc, or iron. You may need to take omega-3s and iodine if you're vegan. Your healthcare practitioner can tell you what supplements suit you best.

Are Prenatal Vitamins Safe?

Most prenatal vitamins are considered safe as long as they are used as prescribed. However, some vitamins, like vitamin A, can be risky even though you need a certain amount for your baby's organ development.(9) Vitamin C is also questionable. If you take too much, the excess may be eliminated through the umbilical cord, which may be dangerous for your baby. Your healthcare practitioner can discuss the pros and cons of taking vitamins A and C.

Additionally, you may wonder if you can take prenatal vitamins even if you aren't pregnant. The short answer is yes, it's generally safe. They may offer benefits a regular daily multivitamin can't in some cases. Your healthcare practitioner can tell you if you need to take a prenatal vitamin and which one, even if you're not planning on becoming pregnant.

How Long Should You Take Prenatal Vitamins?

You should take prenatal vitamins until your healthcare practitioner tells you to stop. Some women even start taking them long before they get pregnant and well after they deliver, especially if you plan on breastfeeding your baby.(1) Taking prenatal vitamins can help ensure you get the nutrients you need while your hormones are still in flux.
