Why Gluten in Supplements Is a Real Concern
Most people associate gluten with bread and pasta — but gluten can also hide in supplements. Fillers, binders, and coatings used in tablets and capsules sometimes contain wheat-derived ingredients. For people with celiac disease or gluten sensitivity, this can be a serious issue.
Even if you don't have a diagnosed condition, many health-conscious consumers prefer to avoid gluten in their supplements as part of a cleaner overall approach to nutrition.
How Gluten Ends Up in Supplements
Gluten can appear in supplements through:
- Fillers and binders — used to hold tablets together; some are wheat-derived
- Coatings — tablet coatings sometimes contain gluten
- Cross-contamination — facilities that process both gluten-containing and gluten-free products can introduce trace amounts
- Flavorings and additives — some natural flavors are derived from gluten-containing grains
What to Look for on the Label
When shopping for gluten-free supplements, look for:
- An explicit "Gluten-Free" label on the packaging
- Third-party certification from organizations like the Gluten-Free Certification Organization (GFCO)
- A "Certified Gluten-Free" seal, which requires testing to below 10 ppm (parts per million) — stricter than the FDA's 20 ppm standard
- Brands that manufacture in dedicated gluten-free facilities
