- Also listed as
- Vitamin B12 supplements
- Best swap
- Cyanocobalamin tablets
Why
Cyanocobalamin and methylcobalamin used in supplements and fortified foods are produced by bacteria. This is the one nutrient every vegan needs reliably from supplements or fortified food; the same B12 is fed to farmed animals.

Questions people ask
Is Vitamin B12 supplements 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.
