Calcium carbonate antacids: cost, sugar-free options, and availability

Calcium carbonate chewable tablets are sold under many brand and store-brand labels. Sugar-free versions may be useful for people limiting sugar intake, but ingredients and sweeteners vary by product.

Compare active ingredient, strength per tablet, sugar-free status, quantity, and unit price. Store brands are often substantially cheaper than national brands.

Ask a pharmacist or clinician before frequent use if you have kidney disease, high calcium levels, a history of kidney stones, are pregnant, or take medications that may interact with calcium. Antacids can affect absorption of some drugs.
