A2A2 milk relates to the type of casein (protein) in milk. In recent studies, A1 milk (predominantly produced by Holstein and Holstein-cross cows) has been show to cause increased digestive distress and responses similar to lactose intolerance. A2 casein (found predominantly in non-Holstein cows), in these studies, did not produce these adverse reactions. Sheep, goats, and people naturally produce A2 casein proteins.
