TUMS provides fast-acting relief from the pain of heartburn. The secret is its primary active ingredient – calcium carbonate, which is mined from limestone – that quickly gets to work tackling the symptoms of heartburn. More than 60 million Americans suffer from the discomfort of heartburn every month.

In 1928, James Harvey "Jim" Howe (born 1873 College Corner, Ohio, and died 1960 Webster Groves, Missouri), a pharmacist in St. Louis, Missouri, developed Tums in the basement of his home while treating his wife's indigestion.

One of the main reasons TUMS works so well is its active ingredient, calcium carbonate. Calcium carbonate is a naturally mined product and the primary active ingredient in all TUMS products. It goes to work in seconds to neutralize stomach acid and relieving heartburn.

TUMS heartburn medicine neutralizes acid on contact, giving you fast relief. With pleasant melon berry flavors, these sugar free heartburn tablets are also refreshing. Adults and children 12 years and older may chew two to four calcium carbonate tablets as symptoms occur or as directed by a doctor.

Works and taste good! The sugar-free Tums tasted just like the original and worked just as good. I also do not find them to be very chalky like some antacids can be . I will definitely be purchasing the sugar-free from now on.

The bottom line Tums rarely have serious side effects. But they're possible. These include kidney problems, like kidney stones, and heart problems. If you have certain health conditions, like kidney disease or heart failure, you may be at a higher risk for side effects of Tums.

Don't take antacids frequently. If you experience symptoms of heartburn or indigestion daily, reach out to your healthcare provider to look into the cause of your symptoms.

Tomato products: This includes tomato sauce and any creamy sauces with a tomato base. Chocolate: Sad, but true! Peppermint: This includes peppermint-flavored candy. Garlic and onions: If you find yourself dealing with heartburn at home, try avoiding these delicious (but triggering) common ingredients.
