Why
Saccharomyces cerevisiae is a fungus, not an animal. Most brands are fortified with B12 produced by bacterial fermentation, which is also vegan. A few unfortified versions contain no B12 at all, which matters nutritionally rather than ethically.
What to check on the label
- The ingredient list on your own pack — Nutritional yeast recipes differ by country and change over time
- Milk, whey, casein, lactose, egg, honey, gelatin, carmine (E120) and shellac (E904) in the list
- "May contain milk" is an allergen cross-contamination note, not an ingredient — most vegans still buy it

Questions people ask
Is Nutritional yeast certified vegan?
Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.
Does the answer change between countries?
Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
