About Is It Vegan?

Is It Vegan? is a free tool that checks ingredient lists against a curated database of animal-derived, plant-derived, and source-dependent ingredients. It runs entirely in your browser — nothing you paste is uploaded or stored.

How the database is built

Each entry is researched from ingredient and additive references, including common E-numbers and alternative names. Ingredients are classified as vegan, not vegan, or "maybe" when the source genuinely varies between manufacturers (for example, mono- and diglycerides or vitamin D3).

Limitations

No automated checker can be perfect. Manufacturers reformulate, and umbrella terms like "natural flavors" can legally hide animal derivatives. Treat this tool as a fast first pass, not a certification. When it truly matters, contact the manufacturer directly.
