UK Food Allergen Labeller

UK food sellers must display allergen information before customers purchase. Food Allergen Labeller helps you meet this legal requirement by creating an ingredient library where you tag allergens for each ingredient, then link them to your products. The app automatically calculates allergen profiles for your entire product catalogue and displays them on your storefront through a Theme Editor block compatible with any Shopify 2.0 theme—no coding required. Track and display all 14 UK-mandated allergens with separate "Contains" and "May Contain" labels as regulations require. Compound ingredient support ensures hidden allergens are never overlooked, keeping your allergen information accurate across every product.
