Why It's Confusing
Casein is often listed separately from "milk" on ingredient labels, which gives the impression a product without "milk" might be plant-based. Under EU labelling rules, casein and caseinates must be flagged as a milk allergen, which is the most reliable tell on European packaging [[2]](#source-2). It is also a common ingredient in products marketed as non-dairy, lactose-free, or vegetarian.
Some dairy-free cheeses in the United States and select markets contain sodium caseinate and are not vegan despite the dairy-free labelling. This pattern of misleading "free-from" framing also appears with animal proteins like collagen and gelatin.
Where It Commonly Appears
- Dairy-free cheeses that are not explicitly labelled vegan
- Protein powders and high-protein drinks
- Coffee creamers
- Processed meats and sausages, where casein is used as a binder
- Bakery glazes
- Some wines, where casein is used in fining
- Cosmetics as a hair and nail-strengthening ingredient
What To Watch For
- Casein, caseinate, calcium caseinate, sodium caseinate, potassium caseinate
- Milk protein, milk derivatives
- The "contains milk" allergen line [[2]](#source-2)
- Look for "vegan" certification rather than "dairy-free" when scanning cheese alternatives
Vegan Alternatives
- Fully vegan-labelled dairy alternatives
- Brands explicitly avoiding casein: Violife [[3]](#source-3), Miyoko's Creamery [[4]](#source-4), Follow Your Heart (most lines), Oatly, Alpro, Califia Farms
