Most mayonnaise is naturally gluten-free and safe for celiac disease. Learn which brands are verified safe, what to watch for in flavored varieties, and how to avoid hidden gluten in mayo-based foods.
The short answer: Most plain mayonnaise is naturally gluten-free and safe for celiac disease. Traditional mayo is made from eggs, oil, vinegar or lemon juice, and seasonings — all naturally gluten-free ingredients. However, some flavored varieties and mayo-based products may contain gluten, so label reading is essential.

Restaurant Mayo Concerns
At restaurants, mayo itself is usually safe, but watch for:
- Shared knives/utensils — Used on bread, then in mayo

Deli Counter Risks
Deli-prepared mayo salads have cross-contact risks:
- Shared scoops with wheat-containing items
- Prepared in facility handling wheat

For strictest safety: Make mayo-based salads at home with verified GF ingredients.
