Is It Vegan?
Search any food, ingredient, E-number, or product label. Get an instant verdict, verified origin explanation, and plant-based swaps.
How the verification engine works
1. Natural Language Parser
Strips punctuation, filler words ("is", "can vegans eat"), and maps 100+ aliases, E-numbers, and chemical names.
2. Knowledge Graph Lookup
Evaluates animal derivation, manufacturing methods (e.g. bone char filtration), and allergen categories.
3. Smart Swap Integration
Whenever a non-vegan item is detected, instantly recommends culinary plant swaps with exact conversion ratios.
Frequently Asked Questions
What does "Is It Vegan" check?
Our engine evaluates single ingredients, E-numbers, chemical names, food products, and full ingredient labels against verified vegan standards.
What makes an ingredient non-vegan?
Ingredients derived from animal slaughter (meat, gelatin, lard, tallow, animal rennet), animal secretions (dairy, whey, casein, eggs, honey, beeswax, lanolin), or insect harvesting (carmine E120, shellac E904) are strictly non-vegan.
How does the tool handle ambiguous ingredients?
Ingredients like mono- and diglycerides (E471), white cane sugar (bone char filtration), and Vitamin D3 are flagged as "May Be Non-Vegan" with clear guidance on what to look for on labels.
Can I paste a full product ingredient list?
Yes! The tool automatically tokenizes full ingredient lists, parses every item, and highlights all problematic animal derivatives.
