Why this reading matters
Gluten-free is a voluntary claim with defined US conditions, including less than 20 parts per million gluten. Wheat-free and an ingredient list with no obvious gluten names are not equivalent evidence. 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
A label scan cannot measure trace gluten or verify manufacturing controls.
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.
