Scan any US food or drink barcode and instantly see whether it contains Red 40 — the dye that requires a hyperactivity warning label across the entire European Union.
Red 40 (Allura Red AC, E129) is the most-used artificial dye in the United States. It shows up in cereal, candy, fruit snacks, sports drinks, gummy vitamins, and even some over-the-counter children's medications.
In Europe, every product containing Red 40 must carry a warning label that says it may affect children's activity and attention. In the US, no such warning is required. We built this scanner so you do not have to read every ingredient list out loud in the grocery aisle.
Scan one product right now and find out whether Red 40 is hiding in your pantry. Free. No signup.
