According to this helpful livestrong.com article, "sodium caseinate is the biochemical name for casein, which is a type of protein found in the milk from all mammals. Casein, [which comes from the Latin word (caseus) for “cheese”], is a major component of commercial cheese and its principle source of protein. Casein is also used as a food additive and for industrial purposes. Some people are allergic to sodium caseinate." Products with sodium caseinate are, of course, not vegan products.
