Classic Tums chewable tablets are vegan. The calcium carbonate comes from limestone, and the other ingredients are synthetic or plant-based. Tums Chewy Bites aren't vegan: every flavor lists beeswax and shellac, and Assorted Berries and Berry Shake also contain carmine.
We previously said Tums were vegan apart from one dairy-containing product. We've updated this page after checking the current Chewy Bites ingredients.
Tums are a good example of why you check the product, not the brand. The classic chalky tablets are vegan. The newer Chewy Bites use three insect- and bee-derived ingredients.

What's wrong with Chewy Bites
Chewy Bites are coated to stop them sticking together. That coating uses beeswax and shellac, a resin made by the lac insect, and the berry flavors are colored with carmine, made from crushed cochineal insects. None of these are vegan.
Vegan alternatives
If you need a chewable antacid, stick to classic Tums tablets. Original Pepto-Bismol liquid is also free of animal ingredients, but the LiquiCaps contain gelatin.
How to check any chewable tablet
Chewable tablets and lozenges often use the same coatings and colors as candy. Look for:
- Carmine, cochineal or E120: an insect-based red or pink.
- Shellac or confectioner's glaze: from lac insects.
- Beeswax: from bees.
- Gelatin: in capsules and some chews.
- Lactose: a milk sugar often used as a filler in tablets.
- Magnesium stearate: usually plant-based in modern products, but can be animal-derived.
Ask a pharmacist if you need help choosing a product that suits your diet.
The bottom line
Classic Tums tablets are vegan. Tums Chewy Bites aren't. Read the label on anything with a soft chew or a glossy coating.
