PRODX

Allergen scanner

Check a product's declared allergens

You declare your allergies once. After that, every scan checks them for you and surfaces a conflict before anything else. PRODX is not a safety guarantee: for an allergy, the current physical packaging remains the only reference.

How the check works

  1. 01

    You declare your allergies

    At sign-up you set your allergens and their severity — mild, moderate or anaphylactic. You can also create profiles for your children.

  2. 02

    You scan a product

    The barcode identifies the product and pulls its declared allergens from Open Food Facts.

  3. 03

    The conflict comes first

    A matching allergen appears above the score, not beside it. “May contain” statements are shown separately from declared ingredients.

  4. 04

    The verdict is capped, not averaged

    An allergen conflict cannot be offset by good nutrition. It is a stop, however good the product is otherwise.

What the check covers

  • Declared allergens

    What the manufacturer states is present in the product, as recorded in the product entry.

  • Possible traces

    “May contain” statements are shown apart, because they do not carry the same status as a declared ingredient.

  • More than one profile

    Child profiles let you check a product for someone other than yourself, with their own allergens.

  • Missing information stays missing

    If allergens have not been recorded, PRODX says so plainly instead of showing a reassuring result.

Why severity matters

A mild intolerance and an anaphylactic allergy are not read the same way. That is why PRODX records severity alongside the allergen itself: the same product does not warrant the same warning for every person. This does not make a product safer — it makes the information clearer for the decision you have to make.

A concrete example

You are shopping for a child with a tree-nut allergy. You switch to their profile and scan: one product shows the declared allergen, another shows a clearly separated “may contain nuts” statement. You know immediately which one deserves a look at the packaging, and which one to put back.

Read this before relying on it

PRODX can only check what has been declared and recorded. The data comes from Open Food Facts and can be incomplete, wrong, or reflect an earlier recipe; manufacturers change formulations and production sites without notice. A result with no conflict is therefore not clearance: it is the absence of a known conflict. For an allergy, always read the current physical packaging, and follow the guidance of your doctor or allergist. PRODX provides information, not medical advice.

Common questions

Can PRODX tell me a product is safe for me?
No. PRODX tells you whether a product declares an allergen that is in your profile, which is information, not a safety guarantee. The decision, and checking the packaging, are yours.
Are “may contain” statements taken into account?
They are shown, and shown separately from declared allergens, because their regulatory status is different. How much weight to give them is your call.
What happens if allergen data is missing?
PRODX shows the information as unavailable. Missing data is never presented as the absence of an allergen.
Can I check a product for my child?
Yes. Child profiles carry their own allergens, and the scan runs against the selected profile.
Does the allergen check cost anything?
No. Scanning, verdicts and allergen checks are free.
