TUMS vs Rolaids Buying Guide
Both TUMS and Rolaids are over-the-counter antacids that neutralize stomach acid quickly — usually within minutes. They are often stocked side-by-side, and many people grab whichever is on sale. But there are real differences worth knowing.
Active Ingredients
TUMS contains only calcium carbonate, which reacts with stomach acid to form calcium chloride, water, and carbon dioxide. Each regular-strength tablet contains 500 mg of calcium carbonate; ultra-strength versions contain 1,000 mg. As a side effect, you also get a modest calcium supplement — about 200 mg per tablet at ultra strength. Rolaids contains both calcium carbonate and magnesium hydroxide. The magnesium works more slowly than calcium carbonate but helps prevent acid rebound (a temporary spike in stomach acid after the antacid wears off). The dual-ingredient formula is why Rolaids says it treats "more symptoms" — the magnesium helps with indigestion beyond pure acid neutralization.
Speed of Relief
Both products start working within 5 minutes of chewing. Clinical differences are minimal at standard doses. Neither is meaningfully faster than the other for typical heartburn after a meal.
When to Choose TUMS
Pick TUMS if you are also trying to increase your calcium intake (common for women over 50), if you prefer a wider flavor selection (Chewy Bites, smoothie variants), or if your primary complaint is acid-related heartburn with no bloating component. TUMS is also slightly less likely to cause loose stools, which magnesium can do at higher doses.
When to Choose Rolaids
Pick Rolaids if your symptoms include bloating or gas alongside heartburn, if you have experienced acid rebound with TUMS, or if you want a product that covers slightly more digestive territory. The magnesium hydroxide component gives Rolaids a mild laxative property, which can be helpful if constipation is also a concern.
Dosage and Safety Notes
Both products should not be taken for more than two weeks without consulting a doctor. Overuse of calcium-based antacids can cause hypercalcemia (milk-alkali syndrome) in rare cases. If you need antacids daily, talk to a physician about an H2 blocker or proton pump inhibitor, which address the underlying acid production rather than just neutralizing it.

TUMS Ultra Strength Chewable Antacid lists calcium carbonate as the sole active ingredient at Ultra Strength concentration — a higher per-tablet active ingredient level than the standard and Extra Strength TUMS variants in the product line. The 72-count peppermint format provides per-tablet cost among the lowest in this comparison when calculated across package size. A factual ingredient distinction between TUMS and Rolaids is the formula composition: TUMS Ultra Strength contains calcium carbonate only, while Rolaids formulas combine calcium carbonate with magnesium hydroxide — the cons on this product specifically note the absence of a magnesium component. At $5.48 for 72 tablets, TUMS Ultra Strength is the lowest-priced product on this page on a per-tablet basis against the TUMS 72ct at $9.98 (same count, higher price from a different vendor listing) and the Rolaids Ultra Strength Chewable options at $4.99 and $7.99 for their respective counts. The per-tablet value at $5.48 is the clearest competitive advantage for this listing. As the cons note, the formula contains calcium as the only active ingredient — buyers specifically looking for a dual-ingredient formula combining calcium carbonate with magnesium hydroxide will find that combination in the Rolaids options on this page instead. Buy TUMS Ultra Strength Peppermint 72ct at $5.48 if you want the Ultra Strength calcium carbonate formulation at the lowest per-tablet cost in this comparison and prefer a peppermint flavor chewable. Skip it if the magnesium hydroxide component alongside calcium carbonate is important to you — that combination is the key ingredient differentiator in the Rolaids formulas also on this page.

Bulk economics are the defining feature of the 160-count TUMS Ultra Strength Peppermint pack at $9.98 — the same Ultra Strength calcium carbonate formulation as the 72-count listing on this page, in a quantity that roughly doubles the per-bottle supply for less than double the price of the smaller pack. At $9.98 for 160 tablets, the per-tablet cost is lower than the 72-count TUMS option also on this page, making this the preferred format for households that use TUMS as their primary chewable antacid on a regular basis. The cons note portability is reduced at this tablet count — the larger bottle format isn't suited for carrying in a bag or pocket. The 160-count TUMS Ultra Strength at $9.98 offers a lower per-tablet cost than the TUMS 72-count at $5.48 on this page. Both use the identical Ultra Strength calcium carbonate formulation without a magnesium hydroxide component. Against the Rolaids options on this page (Assorted Fruit at $4.99 and Mint at $7.99, both 72-count), the TUMS 160-count wins on per-tablet cost while delivering the TUMS single-active-ingredient calcium carbonate formula rather than Rolaids' dual calcium carbonate + magnesium hydroxide composition. Buyers who specifically want the dual-formula combination will need to select one of the Rolaids options regardless of pack size considerations. Buy the TUMS Ultra Strength 160ct at $9.98 if you use TUMS regularly and want to reduce per-tablet cost by buying in bulk. Skip it if portability matters — the smaller 72-count TUMS pack on this page is a better travel or on-the-go format at a slightly higher per-tablet cost.

Rolaids Ultra Strength Antacid Chewable Tablets list both calcium carbonate and magnesium hydroxide as active ingredients — a dual-ingredient formula that differentiates Rolaids from TUMS, which lists calcium carbonate as its only active ingredient. The combination of both compounds in one tablet is the characteristic distinction of the Rolaids formula. The 72-count Assorted Fruit format at $4.99 is the lowest-priced product on this page on a per-tablet basis among all four options, making it the entry price point for the dual-formula composition. At $4.99 for 72 tablets, Rolaids Assorted Fruit is the lowest-priced product on this page. The TUMS Ultra Strength 72-count is $5.48 for the same count, containing calcium carbonate as the only active ingredient. The Rolaids Mint 72-count at $7.99 is the identical Rolaids dual-formula in mint flavor — a $3 premium over the Assorted Fruit for flavor preference alone. The TUMS 160-count at $9.98 provides more than twice the tablet count for roughly double the price of this Rolaids option but with the TUMS single-ingredient formula. The cons note that magnesium hydroxide at higher doses has a documented laxative effect — a known pharmacological property of magnesium-containing formulations. Buy Rolaids Ultra Strength Assorted Fruit 72ct at $4.99 if you want the calcium carbonate + magnesium hydroxide dual-ingredient formulation at the lowest per-tablet price on this page and prefer fruit-flavor chewables. Skip it and choose the Rolaids Mint 72-count if you specifically want mint flavor in the same Rolaids formula — noting the $3 premium for that flavor preference.

Mint flavor is the primary differentiator of the Rolaids Ultra Strength Antacid Chewable Tablets Mint 72-count at $7.99, which uses the same dual-ingredient formula (calcium carbonate + magnesium hydroxide) as the Rolaids Assorted Fruit option also on this page. For buyers who prefer a mint chewable over fruit-flavored variants — a meaningful preference for a product taken regularly — the mint option delivers the Rolaids dual-formula in the preferred flavor profile. The 72-count size and Ultra Strength concentration match the Assorted Fruit variant in every specification except flavor and price. At $7.99 for 72 tablets, the Rolaids Mint costs $3 more than the Rolaids Assorted Fruit 72-count ($4.99) for the same formula and count — a flavor premium paid purely for the mint profile. Against the TUMS options on this page: TUMS Ultra Strength 72-count at $5.48 uses calcium carbonate only (no magnesium hydroxide), while the TUMS 160-count at $9.98 provides more than twice the tablet count for a small price increment above this Rolaids option — but with the TUMS single-ingredient formula. Buyers choosing between Rolaids Mint and TUMS peppermint are deciding both a formula difference (dual vs. single active ingredient) and a flavor difference simultaneously. Buy Rolaids Ultra Strength Mint 72ct at $7.99 if you specifically want the Rolaids dual-ingredient formula (calcium carbonate + magnesium hydroxide) in a mint-flavored chewable and the $3 flavor premium over the Assorted Fruit variant is acceptable. Skip it and choose the Rolaids Assorted Fruit at $4.99 if you're indifferent between mint and fruit flavoring — the formulation is identical at a meaningfully lower price.
