What the label cannot settle

This page does not define a legal plant-based standard or certify a product as vegan.

Put the check to work

Compare the exact words and amounts on your package with the example. If a panel is missing, a photo is unreadable or the manufacturer has not disclosed a detail, keep that detail as unknown. A different flavor, shade or formulation needs its own check.

For names used in this check, read sesame. For the full reading method, use our food label guide. The food allergies guide adds context for your needs.
