There is no scientific evidence that Tums (calcium carbonate) causes autism. Tums is one of the most commonly used over-the-counter antacids during pregnancy and is generally considered safe by medical professionals.

Tums vs. Other Antacids

Some research has examined proton pump inhibitors (PPIs) like Prilosec and their potential associations with autism, but Tums works differently. Tums is a simple calcium-based antacid that neutralizes stomach acid directly, rather than blocking acid production at the cellular level like PPIs. No studies have linked calcium carbonate antacids to autism.

Heartburn During Pregnancy

Heartburn affects up to 80% of pregnant women. The American College of Obstetricians and Gynecologists considers calcium-based antacids like Tums a first-line treatment. The calcium in Tums can even contribute to meeting daily calcium requirements during pregnancy.

What Actually Causes Autism

Autism is primarily genetic, with environmental factors during brain development playing a secondary role. Simple antacid use is not among identified risk factors.
