Tums Antacid Assorted Berries

Tums is a well-known brand of antacid chewable tablets primarily composed of calcium carbonate. Originally created in 1928 by pharmacist James S. Howe in St. Louis, Missouri, the brand was developed to treat indigestion. For nearly a century, the core manufacturing has been centered in St. Louis, Missouri, though distribution spans globally.

Following its invention, the brand was produced by the Lewis-Howe Company. Over decades of corporate mergers and acquisitions, ownership transitioned through companies like SmithKline Beecham and eventually GlaxoSmithKline (GSK). In 2022, GSK spun off its consumer healthcare division into a new independent company called Haleon. Today, Haleon is the ultimate owner of the Tums brand, maintaining its headquarters in the United Kingdom while continuing to serve the global market as a leader in consumer health products.
