From morning sickness to food aversions, from strong cravings to heartburn, it’s no wonder you can’t always get all of your nutrients through diet alone during pregnancy.
Growing a baby takes time and a host of essential vitamins and minerals.
And while many obstacles can prevent you from getting the best nutrition possible, taking a prenatal vitamin will help you meet all of your nutritional needs.
A prenatal vitamin won’t replace a healthy, well-balanced diet. However, it can ensure that you and your baby receive optimal nutrition for healthy growth and development.

Prenatal vitamins are multivitamin supplements designed to provide you with crucial nutrients needed when trying to conceive, during your pregnancy, and after your pregnancy.
Before, during, and after your pregnancy, your body has an increased need for specific nutrients. These nutrients include folic acid, iron, calcium, vitamins A and C, the B vitamins, and DHA, an omega-3 fatty acid.
Prenatal vitamins can come in various forms. Most are capsules or pills, but you’ll also see gummies and even liquid prenatal vitamins on the market.
Additionally, they can be a prescription or can be found at many retailers as over-the-counter.
While many of the nutrients you need will come from your food, prenatal vitamins will fill in the gaps or provide a nutrition safety net to ensure you and your baby get the essential vitamins and minerals for optimal growth and development.
Prenatal vitamins can reduce the risk of birth defects.
Prenatal vitamins contain an array of vital nutrients to help support the development of your baby.
Many studies have found that getting adequate amounts of folic acid before conception and early pregnancy can reduce the risk of neural tube defects, in addition to congenital heart defects in your developing baby. (1)
Prenatal vitamins are a great “dietary insurance plan.”
Eating a perfectly well-balanced diet during your pregnancy can be a struggle. A prenatal vitamin will ensure that you’re receiving the optimal nutrition for you and your growing baby.
Prenatal vitamins may provide relief from nausea.
While some prenatal vitamins can make nausea worse, some are formulated to help ease morning sickness.
Vitamin B6 has been shown to help ease nausea, so if you’re struggling with nausea, ask your health care provider about taking a supplement with more vitamin B6. (2)
The American College of Obstetricians and Gynecologists (ACOG) recommends prenatal vitamins with the following nutrition profile: (3)
- Folic acid: 600 mcg
- DHA: 200 mg
- Iron: 27 mg
- Calcium: 1,000 mg
- Vitamin D: 600 IU
One of the most important nutrients to look for in a prenatal vitamin is folic acid.
Folic acid is an essential nutrient to consider even before you conceive because taking folic acid before conception can help prevent birth defects of the brain and spinal cord, also known as neural tube defects.
It is recommended that all women of childbearing age get 400 micrograms of folic acid daily. If pregnant, that need increases to 600 micrograms daily.
During pregnancy, DHA is crucial for your baby’s brain development.
While a reference intake for the amount of DHA that should be consumed per day hasn’t been established yet, many health care providers believe that pregnant and lactating women should consume at least 200 milligrams of DHA per day.
Another vital nutrient to look for in your prenatal vitamin is iron. You’ll need twice as much iron to support your health and the health of your growing baby.
Look for a prenatal vitamin with 27 milligrams of iron.
Your baby will require calcium for the development of their bones, teeth, muscles, and nerves.
What your baby doesn’t get through your diet, they will take from your bones. This can lead to a higher risk of osteoporosis later in life.
Getting 1,000 milligrams of calcium from your prenatal supplement will prevent bone loss and support your baby’s healthy growth and development.
Vitamin D works hand-in-hand with calcium to support your baby’s bones, teeth, skin, and eye development. Your prenatal vitamin should provide 600 IU (international units) of vitamin D.
If you or your healthcare provider suspects that you might be deficient in vitamin D, they may recommend increasing your intake to 800 or 1,000 IU daily.
Additional Vitamins and Minerals
Other vitamins and minerals found in different types of prenatal vitamins may also include:
Iodine will help your body produce thyroid hormones, which will support your baby’s brain development.
Unfortunately, mild iodine deficiency is common among pregnant women, and iodine deficiencies have been linked to irregularities in brain development and complications during delivery.
Therefore, the American Academy of Pediatrics (AAP) recommends taking a prenatal vitamin that contains at least 150 mcg of iodine. (4)
During pregnancy, your blood volume increases dramatically. This is a time when your body needs to absorb as much iron as possible. As an iron absorption promoter, vitamin C helps make this possible.
While deficiencies are rare, some studies link zinc deficiency to low birth weight and other problems during pregnancy. (5)
Choline is an essential nutrient that supports the healthy development of your baby’s brain and spinal cord. Much like folic acid, choline can also protect babies against neural tube defects.
Eggs, meat, fish, and some whole-grain cereals are good sources of choline. If you’re eating a well-balanced diet, you may be able to get enough of this important nutrient through diet alone.
If not, ask your healthcare provider about whether a prenatal vitamin that includes choline may be best for you.
The following are factors to consider when choosing the best prenatal vitamin for yourself:
Prenatal vitamins come in various forms, and you’ll find pills, capsules, and gummies to choose from.
For many women, the best prenatal vitamin choice boils down to which one they can tolerate the best.
If the thought of swallowing a large pill makes you queasy, then perhaps taking a prenatal gummy may be the best choice.
The most expensive prenatal vitamin isn’t necessarily the best. Looking closely at the ingredients will give you an idea of the quality of the product.
Additionally, your insurance may be more likely to pay for your vitamins if you have a prescription.
If you have a health savings account, you can generally use that money to pay for your prenatal vitamins as well.
Third-party testing for supplements is a way to help ensure the purity, potency, and quality of a product.
Some common third-party testing seals you may find on the packaging may include Consumer Labs, US Pharmacopeia (USP), and NSF International.
A prenatal vitamin will provide a variety of essential nutrients. The basics should include folic acid, iron, calcium, and vitamin D.
If you’re not eating fatty fish like salmon, you may want to consider a product that also contains DHA.
Many women experience morning sickness along with other gastrointestinal distress during pregnancy. A prenatal vitamin can exacerbate these issues.
Finding a prenatal vitamin that you can tolerate may take some trial and error but finding the best one can make a world of difference in how you feel.

Frequently Asked Questions About Prenatal Vitamins
Why should I take a prenatal vitamin?
Prenatal vitamins fill in the nutrition gaps in your diet to help support your baby’s growth and sustain your pregnancy.
One of the most important and well-researched nutrients found in prenatal vitamins is folic acid.
A folic acid deficiency has been linked with anemia in mothers and congenital disabilities, namely neural tube defects in infants.
Dietary supplementation with folic acid around the time of conception has been known to reduce the risk of neural tube defects in babies.
Prenatal vitamins also provide an array of essential nutrients, including iron, calcium, vitamin D, DHA, and iodine, among others.
These nutrients support your baby’s healthy growth and development and ensure your body also has what it needs.
When should I start taking prenatal vitamins?
Ideally, it would be best if you began taking a prenatal vitamin before conception. Taking a prenatal vitamin before conception will ensure that you have an adequate amount of folic acid to prevent congenital disabilities.
Will I experience any side effects with taking a prenatal multivitamin?
You may feel slightly nauseous after taking a prenatal vitamin. If this is the case, ensure you take it with a meal.
Additionally, some women may experience constipation as a result of the iron found in their supplements. If you’re experiencing constipation, try drinking more fluids and eating more high-fiber foods like fresh fruits, fresh vegetables, and whole grains.
If your constipation is persistent, talk to your health care provider about switching to a prenatal vitamin that doesn’t contain iron.
I’m struggling with morning sickness and can’t take my prenatal vitamin. What should I do?
If taking your prenatal vitamin with food doesn’t help alleviate your nausea, try taking it at bedtime.
You may also consider trying a different prenatal vitamin or taking half a dose in the morning and the other half in the evening.
If your nausea is persistent, speak with your health care provider to find the best solution to meet your individual needs.
How can I tell if a prenatal vitamin is trustworthy since they’re not regulated by the FDA?
Look for a third-party testing seal. These will include either the U.S. Pharmacopeia, NSF International, or ConsumerLab.com.
Seeing this seal means the facility has been cross-checked for proper manufacturing, the product has an accurate ingredient list, and it has been verified to have no toxins or harmful ingredients.
How many prenatal vitamins should I take each day?
Take only one serving of your prenatal supplement every day. Read the bottle to see how many pills make up one daily serving.
If your health care provider thinks you may need an additional supplement, they may recommend you take one in addition to your broad-spectrum multivitamin.
Are prescription prenatal vitamins better than over-the-counter ones?
Some may believe that prescription prenatal vitamins are higher in quality. However, this is not the case, as many prescription prenatal vitamins have a similar nutritional profile to over-the-counter ones.
One potential benefit of having a prescription for prenatal vitamins is that your insurance may cover some, if not all, of the cost.
It is always best to speak with your health care provider about which vitamins and supplements will best meet your individual needs.
What is the difference between a prenatal vitamin and a regular multivitamin?
One of the main differences between a prenatal multivitamin and a regular multivitamin is the amount of folic acid they provide.
It is recommended that pregnant women take 600 micrograms of folic acid per day. While some regular multivitamins may provide folic acid, only prenatal vitamins will provide the ideal amount to prevent neural tube defects. (6)
Taking prenatal vitamins is one of the best ways to ensure you have the nutrients you need to support the healthy development of your baby.
They generally contain all of the essential nutrients that can benefit you and your baby during this critical time.
There is no shortage of prenatal vitamin brands on the market to choose from, and while all of the choices can be overwhelming, look for one with 600 to 800 micrograms of folic acid and at least 18 milligrams of iron.
If your prenatal supplement doesn’t contain DHA, your health care provider may recommend a separate DHA supplement.
Choosing the best prenatal vitamin may be a matter of trial and error as you may tolerate some better than others.
Before taking any supplement, it’s always best to speak with your healthcare provider to make sure it will meet your individual needs.
Try not to take your prenatal vitamin on an empty stomach. This can worsen nausea and vomiting.
Additionally, vitamins can vary in size, smell, and taste. You may find that a particular brand might go down easier than another, so trying different ones is wise.
One vitamin that you don’t want too much of is vitamin A. High levels of vitamin A have been linked to congenital disabilities. (7)
Therefore, it’s important to avoid supplements with more than 100% of the recommended dietary allowance of vitamin A.
After you deliver, you may consider continuing your prenatal vitamins for the duration of breastfeeding or longer to support your nutritional needs.
It is best to speak with your healthcare provider about continuing your prenatal vitamin or any supplement to ensure its safety for you.
