TUMS Assorted Fruit Ultra Strength 1000 Antacid

TUMS is an American over-the-counter antacid brand originally created in 1928 by pharmacist James R. Howe in St. Louis, Missouri, to treat indigestion.

The brand was initially produced by the Lewis-Howe Company and was later acquired by Revlon (Norcliff Thayer), followed by Beecham (subsequently SmithKline Beecham and GlaxoSmithKline). In 2022, GlaxoSmithKline spun off its consumer healthcare portfolio into Haleon plc, which now owns and markets TUMS globally.

TUMS antacid tablets are primarily manufactured in the United States, notably at Haleon's manufacturing facility in St. Louis, Missouri.
