Prenatal vitamins tend to be large because they pack a broad blend of vitamins and minerals into as few pills as possible. Early pregnancy can make that harder. Many women notice a stronger sense of smell, a quicker gag reflex and new food aversions in the first trimester, and a pill that was easy to take before pregnancy can start to feel like a daily obstacle.

A prenatal only helps on the days you take it. If swallowing yours has become a struggle, it's worth understanding what makes some prenatals harder to take than others, and what to look for instead.

Why prenatal vitamins are so large

The main reason is how much they hold. A prenatal combines a broad blend of vitamins and minerals, many of them in significant amounts, and that takes up a lot of space. Minerals such as iron and zinc are usually measured in milligrams rather than micrograms, and their compounds add bulk. A multivitamin that tries to deliver meaningful amounts of many nutrients in one tablet will almost always be big.

The form of the pill matters too. Compressed tablets are dense and dry, and their edges can catch in the throat. Some have a chalky coating that turns sticky once it's wet. Long oval caplets are usually easier to swallow than round tablets of the same size, though a very long caplet can also be difficult.

Taste and smell add to the problem. Formulas that include fish-derived omega-3s such as DHA can have a noticeable smell or aftertaste, and for someone already dealing with nausea, the smell alone can be enough to put them off.

Some prenatals split the daily dose across two, three or more pills. Each pill may be smaller, but you swallow more of them, and there are more chances to miss a dose.

Features that make a prenatal easier to swallow

Softgels. A softgel has a smooth, flexible outer shell that turns slippery when wet. Many people find softgels go down more easily than dry tablets. Softgels also suit oil-based nutrients like DHA, which is why so many prenatals with DHA come in this form.

A smaller pill. The size on the label doesn't always tell you how a pill feels to swallow. Photos that show the pill next to a coin or fingertip help, and so do customer reviews that compare it with other brands.

Little or no taste or smell. This matters most in the first trimester. Keeping softgels in a cool, dry place, away from heat, helps them stay fresh.

One pill a day. A single daily pill means one swallow and a simpler routine.

Gummies and chewables remove the need to swallow a pill, which makes them useful for people with real difficulty. They come with trade-offs. Many gummy prenatals contain no iron, some contain smaller amounts of certain nutrients because of space and taste limits, and some include added sugar. If you choose a gummy, read the label carefully and ask your provider whether you need anything alongside it.

Two techniques shown to make swallowing pills easier

Researchers at Heidelberg University Hospital tested two simple swallowing techniques in 151 adults, including people who reported trouble swallowing pills and people who didn't. Their results were published in the Annals of Family Medicine in 2014.

For tablets, try the pop-bottle method. Place the tablet on your tongue and close your lips tightly around the opening of a flexible plastic water bottle. Drink with a quick sucking motion so the water and tablet go down in one swallow, without letting air into the bottle. In the study, this made swallowing tablets easier in about 60% of attempts.

For capsules and softgels, try the lean-forward technique. Place the capsule on your tongue and take a sip of water, but don't swallow yet. Tilt your head forward toward your chest, then swallow with your head bent. Capsules and softgels float, so leaning forward helps them move toward the back of your throat. In the study, this made swallowing capsules easier in nearly 89% of attempts.

Many people tilt their head back to swallow a pill. For capsules and softgels, the study found that tilting forward works better.

More practical tips

• Take a sip of water before you put the pill on your tongue, so your mouth and throat are already wet.
• Take your prenatal with a meal. Many people find it sits better with food than on an empty stomach. This matters most for formulas with iron, a common reason vitamins feel harsh on the stomach.
• If mornings are hard, try taking it with dinner or before bed.
• Keep the bottle next to something you use every day, such as your water bottle or your toothbrush.
• Ask a pharmacist before splitting or crushing any supplement. Some are designed to be swallowed whole.

When to talk with your healthcare provider

If you regularly can't take your prenatal or can't keep it down, tell your doctor or midwife. They can suggest a different format, adjust which nutrients you take separately, or look into the cause. Trouble swallowing that isn't limited to pills, or that comes with pain, should always be checked by a professional.
