If you're pregnant (or #TTC), you're obviously eating all the kale, salmon, and whole grains you can...right?
LOL, right. Many moms-to-be eat whatever they can for the first few months (what up, saltine crackers and Swedish fish?) thanks to a little thing called morning sickness and a hyper-sensitive nose.
And that, kids, is exactly why prenatal vitamins were invented.
What exactly are prenatal vitamins?
Prenatal vitamins are there to fill in any nutritional gaps and make sure there is an abundance of all the vital nutrients your baby needs to grow—especially magnesium, zinc, calcium, vitamins B and C, and folate, says G. Thomas Ruiz, M.D., ob-gyn at MemorialCare Orange Coast Medical Center in Fountain Valley, California.
Supplemental folate, in particular, is very important as it's been shown to reduce neural tube defects in babies, and you need at least 400 micrograms a day, according to the World Health Organization.
Most of these vitamins are water soluble, meaning you'll just pee out any excess, says Ruiz. (A.k.a. you don't need to worry about OD'ing.) There is one exception to this rule, however: iron, which can be toxic in large doses.
Pregnant women need 30 to 60 milligrams of iron each day, according to the guidelines from the World Health Organization. Most prenatal vitamins come fortified with extra iron, so as long as you're sticking to what's in your daily prenatal (and not supplementing with even more iron), you'll be fine, says Ruiz. (Caveat: If you are anemic, you might need even more than that, so discuss your individual needs with your doctor, says Ruiz.)
Okay, so when do I need to start taking prenatal vitamins—and for how long?
Ideally you should start taking them as soon as you start trying to conceive, says Ruiz. (FYI: It's a myth that they will increase your fertility, though.) Your baby will needs those extra nutrients from the moment of conception, says Ruiz.
Continue to take the vitamins throughout your pregnancy and afterwards, for as long as you're breastfeeding, he advises.
So how do I choose the right prenatal vitamins? (So. Many. Options!)
Sifting through drugstore shelves or Amazon suggestions is super intimidating. So here are the best-selling prenatal vitamins on Amazon—plus, insight from docs as to whether they really work:
1. One A Day Women's Prenatal Multivitamins
This is the most popular brand of prenatal vitamins on the market, and it's a solid choice, says Hillary Wright, M.D., R.D., director of nutrition counseling at Boston IVF and an expert in prenatal nutrition.
It's not necessarily fancy, but it gets the job done for a reasonable price and, best of all, it's been verified by an independent lab so it actually contains what it says it contains, she adds. (Which isn't always the case with supplements as they're not monitored by the FDA.)
2. Nature Made Prenatal + DHA 200 mg Multivitamin
The best thing about this prenatal vitamin: a large dose of DHA, a fatty acid crucial to fetal brain development, says Wright.
"A lot of prenatals advertise they have this but they have a miniscule amount—you want a minimum of 200 mg of DHA per serving ," she says. You can also get DHA by taking a separate fish oil supplement.
3. Vitafusion Prenatal Gummy Vitamins
This is the most popular chewable prenatal on the market for good reason—it has quality ingredients and it tastes good, says Wright.
There is one downside to all gummy vitamins, however: The gummy ingredients (including sugar) displace some of the vitamins. So if you want to make sure you're getting the most nutrition for your money, stick to the pills, she says.
4. Rainbow Light Prenatal One Multivitamin
This super-popular prenatal vitamin is also one of the priciest—but it might be worth it, says Wright. The brand is known for its high quality and it includes prebiotics and probiotics to help keep your gut bacteria (and therefore, you) happy.
These extras aren't necessary, and are best gotten through food, says Wright, but they may be a good addition for some pregnant women, especially if you're struggling to get enough fiber, she add
