Ingredient & product scanner (beta)

Scan a package barcode or paste an ingredient list to check for ingredients that some alpha-gal patients watch. Educational use only — decisions should be individualized with your clinician.

How it works

Barcodes are read locally on your device using the camera (ZXing).
You can capture a photo to decode a barcode or read ingredient text via OCR (Tesseract.js — runs entirely in your browser).
We query the Open Food Facts public API for product data and ingredients.
You can also paste an ingredient list directly from a label or website.
Ingredients are checked against 32 known alpha-gal-related items across three risk tiers:avoid high risk check source
