Can you take prenatal vitamins without being pregnant?

The short answer is yes. You can take prenatal vitamins when you’re pregnant, breastfeeding or when you’re trying to get pregnant. In fact, because much of a baby’s development happens during the early weeks of pregnancy, most experts recommend taking prenatal multivitamins a few months before you start trying to get pregnant.

While prenatal vitamins are a type of multivitamin, they’re formulated specifically to support the nutritional needs of pregnant people. If you’re not pregnant or planning on getting pregnant, it’s best to check in with your doctor about your options and which multivitamins for women best fit your specific needs and lifestyle.

What are prenatal vitamins?

Prenatal vitamins, often referred to as simply “prenatals,” are multivitamins formulated specifically for women who are pregnant or trying to conceive. They help support the nutritional needs of the mother in addition to a healthy diet.

During pregnancy, the daily intake requirements for certain nutrients like folate, calcium and iron—all vital for proper fetal growth and development—increase. Prenatal vitamins for pregnancy help fill these changing needs for expecting women and their developing fetuses throughout each trimester and during breastfeeding.*

When to start taking prenatal vitamins?
The best time to start taking prenatal vitamins is as soon as you’re thinking about trying to conceive. Because pregnancy can be hard to predict, it’s impossible to know how long it’ll take to get pregnant. Often, someone may not know they’re pregnant until a few weeks after they’ve conceived. So starting prenatal vitamins a few months before trying is a good rule of thumb—that’s your best bet to build a solid nutritional foundation to support a healthy pregnancy. You can take prenatals at any point along your motherhood journey, including during your pregnancy and while you’re nursing.*
What do prenatal vitamins do?

The benefits of prenatal vitamins are pretty straightforward. When you’re pregnant or nursing, your body’s nutritional demands change, and it can be hard to get all the nutrients your body—and your baby’s—need to thrive from food alone. Prenatal vitamins are formulated to provide specific nutritional support for a healthy pregnancy and fetal development, as well as during the breastfeeding phase.

Rainbow Light prenatal vitamins, for example, provide 100% or more of the daily recommended amounts of 18 essential vitamins and minerals. The formula promotes healthy brain and neural tube development for babies during the early stages of pregnancy and offers comprehensive support for moms before, during and after pregnancy.*

Do prenatal vitamins help you get pregnant?
There are many good reasons to take prenatal vitamins for pregnancy while you’re trying to conceive. They’re formulated for the needs of both pregnant mothers and developing fetuses, like providing nutrients that support the baby’s brain and spinal cord development. But there is no evidence that taking prenatals impacts your chances of getting pregnant.*
What are the best prenatal vitamins?
Pregnant women need a variety of nutrients to support a healthy pregnancy. Eating the right foods can help cover most of those needs, but prenatals are formulated to help fill nutritional gaps for expectant moms and developing babies. The best prenatal vitamins are the ones that provide vitamins and minerals that are essential before, during and after pregnancy. A few of the most important are folate or folic acid (vitamin B9), iron, iodine and vitamin D.*
What is in prenatal vitamins?

Similar to general multivitamin tablets, prenatal vitamins help provide essential vitamins and minerals to fill nutritional gaps. The difference is that prenatals are formulated specifically for the needs of expecting mothers and their babies. Prenatal vitamins with folic acid or folate (two forms of the essential vitamin B9) are key because these nutrients are essential for DNA synthesis and the normal growth and development of the fetus.

While formulas vary slightly from brand to brand, here’s a list of common vitamins and minerals included in many prenatal dietary supplements:

-Folate or folic acid (vitamin B9)




-Vitamin D

-Vitamin C

-Vitamin A

-Vitamin K

-​​B vitamins, e.g. biotin, thiamin, niacin, riboflavin, pantothenic acid and vitamin B6

-Vitamin E



-Trace minerals like zinc, selenium and copper

What prenatal vitamins should I take?

Finding a formula that supports essential nutritional needs before and during pregnancy is the most important thing when choosing a prenatal. We recommend talking to your doctor for guidance and reading supplement facts labels on products to see which nutrients—and how much of them—are included per serving.

Folate or folic acid (vitamin B9), iron, iodine and vitamin D are a few of the key vitamins and minerals to look for in a prenatal supplement. Scroll up to see a more comprehensive list.*

How long do I need to take prenatal vitamins for?

Taking prenatal vitamins before, during and after your pregnancy is a good way to help ensure you’re meeting your body’s nutritional needs at every stage.

Prenatals are made to replace any other multivitamins or gummy multivitamins you’ve been taking prior to trying to conceive (or getting pregnant). The ideal time to start a prenatal routine is a few months before actively trying to get pregnant to help build a solid nutritional foundation. If you get pregnant, you can keep taking prenatal vitamins throughout each trimester. And like pregnancy, breastfeeding places extra nutritional demands on your body—so it’s a good idea to continue your prenatal vitamin routine postpartum if you’re nursing.*

Are prenatal vitamins necessary?

Prenatal vitamins are a type of multivitamin that contain specific levels of vitamins and minerals to support the growth of a baby in the womb and the changing nutritional needs of the pregnant mother. We strongly encourage customers to consult their doctor for guidance, but the general recommendation is to start taking prenatal vitamins regularly when you’re pregnant or trying to get pregnant.

The goal of taking prenatal vitamins, along with following a balanced diet, is to help support a healthy pregnancy and build a strong foundation for overall health and wellness throughout pregnancy, postpartum and nursing.*

Should you take prenatal vitamins when trying to get pregnant?
Yes. Most experts recommend taking prenatal multivitamins before you start trying to get pregnant. Much of a baby’s development occurs during the early weeks of pregnancy, so if you start taking prenatal vitamins ahead of time, you’ll know you have your nutritional bases covered. Still, we encourage customers to consult their doctor for guidance before starting prenatal vitamins or any supplements.*
