Is Mayo Gluten Free?
Yes — most mayo brands are gluten free.
Mayonnaise is an emulsion of oil, egg, and acid. Those ingredients are naturally gluten free, but some specialty recipes add malt vinegar or share equipment with sandwich spreads.
Mainstream mayo is gluten free.
If the ingredient panel lists oil, eggs, vinegar, salt, and seasonings, mayo is gluten free. Issues only show up when a brand adds malt vinegar, soy sauce, or flavor packets, or when a manufacturer shares lines with breaded products. Certified gluten-free mayo exists if you want extra assurance.
- Eggs and oil are naturally gluten free.
- Watch for malt vinegar or soy-based flavorings.
- Olive-oil-based mayo offers a cleaner fat profile.
Ingredient Analysis
Egg yolks & oil
These core ingredients contain no gluten.
Acids and flavor
Most brands use distilled vinegar or lemon juice; malt vinegar would add gluten, so avoid it.
Shared lines
Private-label mayo occasionally runs on condiment lines that also bottle gravy or soy sauce.
Is it GF/DF/Vegan/Healthy?
Gluten-Free
Look for malt-free recipes; many are certified GF.
Dairy-Free
Traditional mayo contains no milk or lactose.
Vegan
Classic mayo uses eggs; vegan mayo swaps aquafaba for egg protein.
Healthy
Choose avocado- or olive-oil mayo to avoid excess seed oils.
What to Look for on Labels
Spot the acid source
Distilled vinegar is safe; malt vinegar is not.
Check for added sweeteners
“Sandwich spreads” sometimes add HFCS and flavorings that dilute mayonnaise purity.
Use certified GF for celiac households
Whole Foods 365 and many natural brands badge their mayo as gluten free.
