Is it vegan? Ingredients
Is casein vegan?
Quick answer: No. Casein is the main protein in milk, so casein and caseinates are dairy ingredients and not vegan.
Also called: casein, sodium caseinate, calcium caseinate, milk protein, micellar casein
Why it isn’t vegan
Casein makes up most of the protein in cow’s milk. It and its salts (sodium and calcium caseinate) are used to add protein, texture and creaminess to processed foods, coffee whiteners and some “non-dairy” creamers, and to fine some wines.
Because it comes from milk, casein must be emphasised as a milk allergen on labels in the EU and UK. In the US, products marketed as “non-dairy” can still contain caseinates, so always read the ingredient list.
