Why this reading matters
For covered US labels, major allergen sources can be identified in the ingredient names or a nearby Contains statement. Precautionary cross-contact statements are voluntary; their absence is not proof of absence. US Food and Drug Administration.
Ingredients already declared inside Supplement Facts need not be repeated outside it. Other ingredients, such as capsule materials or formulation ingredients, can appear in a separate list. US Food and Drug Administration.
What the label cannot settle
This check does not prove allergy safety or determine whether you should take the supplement.
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 whey. For the full reading method, use our supplements label guide. The food allergies guide adds context for your needs.
