A prenatal you’ll actually take beats one that sits in the cabinet, and for some women that’s a gummy or a chewable. The catch is that gummy prenatals often leave out nutrients that pills include, so it pays to read the label before you rely on one.

The short version

  • Gummies often contain no iron or calcium, according to the NIH. Those are two of the nutrients pregnant women most often fall short on.
  • Every form varies. No federal standard defines what a prenatal vitamin must contain, so ingredients and doses differ in pills, chewables, and gummies alike.
  • What to check on any label: folic acid (not just methylfolate), about 27 mg of iron, about 150 mcg of iodine, and any choline.
  • If a gummy is the only form you’ll take, it can still help. Ask your provider whether you need iron or calcium on top of it.
  • If pills make you queasy, ask about a different product or form instead of stopping.

What a typical prenatal contains

In a 2021 review of 188 prenatal vitamins on the U.S. market, summarized by the NIH, this is how often each nutrient showed up across all forms:

Nutrient Share of prenatals that include it Typical amount Gummies
Folate 98% 800 mcg Check the label
Iron 89% 27 mg Often none
Calcium 78% 200 mg Often none
Iodine 76% 150 mcg Check the label
Magnesium 66% 50 mg Check the label
Choline 40% 25 mg Check the label

Why a missing iron matters

You need 27 mg of iron a day in pregnancy. More than 8 in 10 pregnant women (84%) get less iron from food than the average requirement, according to national survey data from 2001 to 2014, so the iron in a prenatal does real work. A gummy with none leaves a gap. See Iron in Pregnancy.

The folic acid check

Not every prenatal uses folic acid. About 1 in 4 over-the-counter prenatals and 1 in 3 prescription ones use methylfolate instead. Folic acid is the only form of folate proven to lower the risk of neural tube defects, so check which one your product lists. See Why Folic Acid Matters in Pregnancy.

Choosing a form

Pills and capsules are the form most prenatal formulas are built around, and many include both iron and calcium. Large pills can be hard to swallow or turn your stomach.

Chewables and gummies are easier to take for some women, especially with nausea. If you choose one:

  • Check the Supplement Facts panel for iron and calcium. If they aren’t there, ask your provider whether you need them separately.
  • Check the serving size. The amounts on the label are per serving, and a serving of gummies can be more than one.
  • Add up everything you take. If you add a separate iron or calcium product, keep the totals under the upper limits (45 mg of iron a day, 2,500 mg of calcium for women 19 to 50).

Whatever the form, look for a seal from U.S. Pharmacopeia (USP), NSF, or ConsumerLab. The NIH notes that an independent testing group can confirm a product contains what its label says. See Are Prenatal Vitamins Safe?.

If pills make you queasy

Don’t just stop. Ask your doctor or midwife about switching products or forms, and about what time of day to take it. Our article on vitamin B6 for morning sickness covers other options.

What to do now

  • Read your prenatal’s label for folic acid, iron, iodine, and choline.
  • If it’s a gummy, ask your provider about iron and calcium.
  • If you can’t tolerate pills, ask about a different form instead of skipping the vitamin.
  • Look for an independent testing seal.
