You’ve probably seen social media influencers claiming that prenatal vitamins are the secret to stronger hair, glowing skin and better energy. It sounds convincing: If these vitamins are good for moms-to-be and babies, shouldn’t they be good for everyone?
The truth is a little more complicated. Prenatal vitamins are designed for pregnancy and the months leading up to it. They aren’t a one-size-fits-all supplement. Depending on your health and diet, they might offer more nutrients than you need and that might cause problems.
Here’s what Brittany Brooks, DO, a family medicine specialist with Banner Health, said about when prenatal vitamins make sense and when it’s better to choose something else.
What makes prenatal vitamins different?
Prenatal vitamins aren’t “super” multivitamins. They’re formulated to meet the higher nutritional demands of pregnancy and breastfeeding.
“Prenatal vitamins are different than a women’s multi-vitamin because they are designed specifically for women of childbearing age. They provide recommended amounts of key nutrients needed to support a healthy pregnancy,” Dr. Brooks said.
Key nutrients in prenatal vitamins
- Folic acid: Also known as vitamin B9 and folate, folic acid supports early brain and spine development and helps prevent neural tube defects. “Women should get at least 600 micrograms of folate daily, ideally before they conceive,” Dr. Brooks said.
- Choline: This nutrient is not found in all prenatal vitamins but is needed for healthy fetal brain, spinal cord and eye development. It also supports the placenta.
- Omega-3 fatty acids (DHA or EPA): These are essential for brain and eye development.
- Iron: This mineral builds red blood cells and supports the increased blood volume that comes with pregnancy. “Iron helps prevent anemia, which is common in pregnancy,” Dr. Brooks said.
- Calcium and vitamin D: These strengthen bones and teeth for both mom and baby.
- Iodine: The American College of Obstetrics recommends 150 micrograms a day for pregnant women. Iodine is important for the baby’s brain development and the mother’s thyroid function.
Compared with a standard multivitamin, prenatal supplements usually have more iron and folic acid and sometimes less calcium or zinc. They’re designed for supporting pregnancy, not for general use. Taking them if you don’t need them can mean you’re getting too much of certain nutrients and not enough of others.
When taking prenatal vitamins might make sense
In these situations, prenatal vitamins may be useful under medical guidance, even if you’re not pregnant:
- Women of childbearing age: “I recommend these women take a prenatal vitamin even if they aren’t trying to get pregnant right away. This is because spinal cord development occurs very early in pregnancy, before women even know that they are pregnant,” Dr. Brooks said.
- Trying to conceive: “If you are planning for pregnancy there are no downsides to taking a prenatal vitamin,” Dr. Brooks said. Taking a prenatal vitamin one to three months before pregnancy helps build folic acid stores and supports early fetal development.
- Breastfeeding: Nutrient needs stay higher when you’re breastfeeding and you should continue taking prenatal vitamins to meet those needs, especially choline and calcium which can decrease when you’re breastfeeding.
- Certain deficiencies: Your health care provider may recommend a prenatal vitamin if you have iron-deficiency anemia or low folate levels.
- Restricted diets: Vegans and vegetarians may need the nutrients found in prenatal vitamins.
For most healthy adults, a balanced diet and a standard multivitamin are enough. Your body can only absorb so many nutrients.
The potential downsides you should know
While prenatal vitamins are generally safe for those who need them, they may not be right for those who don’t:
- Too much iron: High doses can lead to constipation, nausea or stomach pain. Men, post-menopausal women and people with hemochromatosis or chronic liver disease have lower iron needs and should not take too much iron.
- Too much folic acid: Very high folic acid intake can hide a vitamin B12 deficiency, making it harder to diagnose.
- Missing nutrients: “You may be missing out on other nutrients tailored to your specific needs, for example, vitamins that support bone, skin, hair or other medical conditions you might have,” Dr. Brooks said.
- Cost: Prenatal vitamins often cost two to three times more than a women’s multivitamin. And extra vitamins are usually removed from the body in urine.
Better alternatives for most people
If you’re looking for specific benefits, there may be smarter and more targeted options:
- For hair and nail health: A balanced diet with protein, zinc and biotin or a supplement designed for beauty support.
- For more energy: Evaluate your sleep, stress, hydration and diet. Ask your provider about blood work to check for iron or B12 deficiency before taking extra supplements.
- For everyday wellness: “If you are not planning to become pregnant, a women’s multivitamin may be a better fit. Choose one that aligns with your personal health goals, whether that’s addressing vitamins or minerals you might be missing from your diet or meeting the needs of a specific medical condition you have,” Dr. Brooks said.
Food-first sources of key nutrients
Whole foods deliver fiber and antioxidants that supplements can’t and they’re easier for your body to absorb. Foods that provide the nutrients found in prenatal vitamins include:
- Leafy greens, beans and citrus for folate
- Lean meats, eggs, tofu, fish and lentils for iron
- Dairy or fortified milk alternatives for calcium and vitamin D
- Salmon, walnuts and chia seeds for omega-3s
Making the right choice for you
Before adding prenatal vitamins to your routine, ask yourself:
- Am I planning to get pregnant soon or currently breastfeeding?
- Do I have any diagnosed nutrient deficiencies?
- Does my diet regularly lack iron, folate or other key nutrients?
If the answer is no, you probably don’t need a prenatal supplement. But if you’re unsure, talk to your healthcare provider or a Banner Health nutrition expert before starting anything new. Banner Health’s experts can help review your diet, evaluate lab results and recommend supplements that fit your lifestyle, health goals and budget.
