DIFFERENCE BETWEEN A1 AND A2 MILK
Although both types of milk come from the same source that is the cow, there is a considerable difference in the ratios of lactose (carbohydrate component) and fatty acids (fat component) in both .
However, it is the protein component in the milk that differentiates the two from each other in terms of quality. A1 milk has A1 type of protein (casein) and A2 milk has A2 type of protein (casein). This is important because the way the milk is broken down and metabolised in the system is different.
