Is Pepto-Bismol Gluten Free?
What the Manufacturer Says

We contacted Procter & Gamble (Pepto-Bismol’s manufacturer). They said Pepto-Bismol products do not contain added wheat or gluten, and that the disintegrant sodium starch glycolate is derived from potato starch. However, they cannot confirm the manufacturing facility is gluten-free, so cross-contact cannot be ruled out. They advise speaking with your healthcare provider if you’re concerned.

What the manufacturer told us

Here’s the statement we received directly from the Pepto-Bismol team at P&G:

Why this can be confusing

Brands can avoid intentionally adding gluten yet still manufacture in facilities where cross-contact is possible. Without facility controls or end-product testing for gluten, companies usually avoid a definitive “gluten-free” claim. Formulas and suppliers can also change over time, so it’s smart to verify the exact product you have.
