The Full Answer
Mayonnaise is made from egg yolks, oil, vinegar (or lemon juice), and sometimes mustard — all naturally gluten-free. The vast majority of commercial mayonnaise brands are safe for people with celiac disease.
Hellmann's, Duke's, Sir Kensington's, and most store brands are all gluten-free. Even the distilled vinegar used in mayo is safe — the distillation process removes gluten proteins.
The only rare exceptions would be specialty or flavored mayonnaise products that add wheat-based seasonings, or mayo used in restaurant dishes where cross-contamination could occur (e.g., shared prep surfaces with bread).
