MigraineScan is an educational label-literacy tool. You scan a food barcode and the app checks the ingredient list against a database of common migraine trigger categories — such as tyramine, MSG, nitrates, histamine, artificial sweeteners, caffeine, and alcohol.

It is not a medical device and does not diagnose, treat, or prevent migraines. Always consult a healthcare professional for medical advice.

"No triggers found" means none of the trigger categories in our database were detected in that product's ingredient list. It does not mean the product is guaranteed migraine-safe for you. Food triggers are highly individual — an ingredient not in our database may still be a personal trigger. Use this app as one tool among many, and always read labels yourself.

MigraineScan uses OpenFoodFacts, an open-source community database. Not all products are in their database, especially regional, store-brand, or newly released items.

If you'd like to help add products, visit openfoodfacts.org to contribute product data.

Severity (Mild / Moderate / Significant) — how strongly a trigger category is generally linked to migraines based on its known risk level. This reflects the category itself, not the quantity found in the product.

Detection (Confirmed / Likely present / Inferred) — how clearly the ingredient was found in the product's ingredient list:

• Confirmed — the ingredient was found by name explicitly.
• Likely present — an indirect or ambiguous match was found.
• Inferred — detected indirectly; check the physical label yourself.

The verdict is calculated from the combined score of all detected triggers weighted by their severity, detection confidence, and your personal sensitivity settings.

• SAFE — No triggers from our database were detected.
• REVIEW — One or more ingredients that may be triggers for some people were detected.
• AVOID — Multiple or stronger trigger signals were detected based on your profile.

The verdict shifts based on your sensitivity settings. Setting a trigger to "High" sensitivity makes it weigh more heavily in the score. Setting it to "None" removes it from consideration.

An internet connection is required to look up product data from OpenFoodFacts and to sync your scan history. The camera scanner itself works offline, but the ingredient analysis requires a network connection to fetch the product's ingredient list.

No. Your trigger profile, sensitivity settings, and scan history are private to your account. We do not sell or share your data with advertisers, data brokers, or any third party for marketing purposes. See our Privacy Policy for full details.
