Best Antacid for Heartburn of 2026

The 160-count bottle is the one we leave in the pantry, and that is the point: it turns heartburn relief into something you don't have to think about restocking. Tums Smoothies are chewable, assorted fruit, and labeled with 1000 mg calcium carbonate per tablet, so two tablets carry a serious dose of acid-neutralizing power. The bottle is a pantry purchase, and that is where it belongs.

We recommend it for a household that wants a dependable bottle at home. The tablets go to work on contact, and the fruit flavor is pleasant enough that you'll actually finish the course instead of dreading it. The 1000 mg strength also means you should read the label rather than treating them like candy. It's the bottle we keep in the cabinet.

What we appreciate is the value of the big format: fewer reorders, a bottle that lasts, and a flavor assortment that keeps the routine from getting old. For a nightstand, kitchen cabinet, or shared office drawer, the supply becomes the advantage. It's a simple, fast antacid in the size that makes sense for a household.

Heartburn that shows up when you lie down is a different problem from the burn that hits after a spicy lunch. Gaviscon is built for that setting: extra-strength cherry tablets that are chewable and formulated to neutralize stomach acid while helping keep it down for hours.

The 100-count bottle is easy to keep on a nightstand, and the tablets are fast-acting in the way you need at that hour. It's a chewable, not a swallow tablet, so it's simple to take without water. The formula is the differentiator: it's designed to neutralize acid and help keep it down, rather than only taking care of what is already there.

Against the Tums picks, Gaviscon is less of an all-purpose pantry antacid and more of a targeted nighttime tool. The 100-count bottle lasts, and the chewable format is easy to keep within reach. If your heartburn is worst when you're horizontal, this is the one in this group we recommend.

One chewable tablet that combines an acid reducer with an antacid is the appeal here, and Pepcid Complete is the pick in this group when heartburn needs to stay away longer than a plain chew can manage. Each tablet contains 10 mg famotidine plus 800 mg calcium carbonate, so it starts working fast and then keeps reducing acid. That one-tablet convenience is why we recommend it for nighttime or for heartburn that tends to come back.

The 72-count bottle is easy to keep in a bathroom cabinet, and the berry flavor is pleasant enough to take without a chaser. We like that it's a chew, not a swallow pill, so you don't need water. It's a combination product, though, and that changes the purchase: famotidine can interact with other medicines, so check with a pharmacist before adding it to a regular routine. If you want a simple calcium carbonate tablet, this is more drug than you need.

Against the Tums picks, this is the one for a planned night or a pattern of heartburn that keeps returning, not for a single episode you want to treat and forget. The 72-count bottle is a decent supply, and the chewable format is easy to take when you're already in bed. We still keep a plain antacid around for a mild flare, because this one is built for longer coverage rather than a quick top-up.

This is not the antacid to hand to everyone. Alka-Seltzer Heartburn + Pain combines aspirin with an antacid, which makes it a different purchase from a plain chew. It's built for heartburn that arrives with a headache, backache, or the general body ache of a long day. The tablets dissolve in water and start working fast, and the 72-count package is split into 36 individual packets, which makes it easy to keep a dose in a bag or desk.

We recommend it for the specific overlap of heartburn and pain, not as a universal antacid. You need four ounces of water and two tablets, so it's not the thing to take in a car or at a concert without a glass. The effervescent format is pleasant in a fizzy, old-fashioned way, and the packets are genuinely portable. The combination is the reason to choose it, but it also means you should read the label before you add it to a bag.

Against the chewable picks, this is the one that does two jobs at once, and that is its whole reason to exist. The 72 tablets in 36 packets give you a travel-friendly supply, and the effervescent action is easy to drink when you're already feeling rough. If you want a simple chew to keep in a bag, look to the Tums picks; if heartburn comes with a headache, this is the more efficient choice.

A 200-count container solves a different problem than a purse-sized roll. Alka-Seltzer Extra Strength Heartburn ReliefChews are a big, non-chalky fruit chew that starts neutralizing acid in seconds, and the container is built for a desk drawer, a shared cabinet, or a car console. It's a supply, not a single dose.

The chews are the draw for anyone who dislikes gritty tablets. The assorted fruit flavor is pleasant, and the texture is softer than a classic chalky antacid, which makes them easier to finish. The 200-count size is the value play, but it's also a commitment: you need a place to keep it, and the container is best kept sealed. It suits a breakroom or a bathroom cabinet.

Against the smaller chews here, this is the bulk option, and the 200-count supply is the reason to choose it. We recommend it for a shared drawer, a breakroom, or a car console, where a big container earns its space. The flavor is mild enough for repeated use, and the non-chalky finish is a real improvement over old-style tablets. If you need something for a jacket pocket, a smaller container is easier to carry.
