What is A2A2?

There are two common types of beta casein proteins found in cow's milk: A1 and A2. Breeds of cows, like Guernsey, can be bred to produce milk without the A1 gene: A2A2 milk.

The two proteins are digested differently. The milk sensitivity you may experience may not actually be a reaction to lactose, but rather the A1 protein.

Since A2A2 milk can only be produced naturally from cows and does not contain the A1 protein that causes problems with digestion, it provides the opportunity to reintroduce real dairy products back into your diet!
