Vegan Classification Methodology

Additives are classified based on publicly available regulatory information and general ingredient origin principles.

• Plant-based: derived from plants or plant fermentation
• Animal-derived: sourced from animal ingredients or by-products
• Synthetic or microbial: produced through chemical synthesis or microbial fermentation
• Unknown / variable: sourcing may differ depending on manufacturer or region

Some additives may have different classifications depending on manufacturing methods or regional regulatory differences.

Limitations

While this app uses publicly available regulatory sources, ingredient sourcing and production methods may vary between manufacturers and countries. Information may change as new scientific or regulatory updates become available.
