This creamy, delicious full-bodied milk comes from specially selected cows that naturally produce only the A2 protein and no A1 protein. For some of those people who have trouble drinking regular cow’s milk, it might be because of the A1 protein. And a2 Milk™ might make a difference. Many people say it just feels better in their bodies.
