20 ppm Gluten Threshold
The 20 ppm gluten threshold is the U.S. FDA limit for gluten-free labels—helpful for most celiac diets but not a guarantee for every sensitive person.
The 20 ppm gluten threshold is the FDA gluten-free labeling standard in the United States—products labeled gluten-free must contain less than 20 parts per million gluten. It protects most people with celiac when intake is occasional and portions normal, but highly sensitive individuals or stacked exposures from many borderline foods can still react.
Certification programs sometimes test below 10 or 5 ppm.
Common questions
-
Can celiac patients eat 20 ppm foods daily?
Most tolerate labeled gluten-free foods within 20 ppm in normal portions, but daily volume and extra cross-contact at home still matter. Track patterns; consider certified lower-ppm products if reactions continue.
