The a2 Milk® difference

It all starts with the cows. We conduct a simple DNA test on a tissue sample taken from the cows to identify cows that naturally produce milk with only A2-type beta-casein protein and no A1 protein. Every batch is then tested again before it reaches your fridge, so you can feel confident in what you're drinking.

The result? Milk that may be easier on digestion for some people*, with all the goodness of natural dairy milk.

*a2 Milk® comes from cows specially selected to naturally produce milk with only A2-type protein, and no A1, so may be easier on digestion than regular milk for some milk intolerant individuals when consumed as part of a healthy, varied diet.

Understanding A1 and A2-type proteins

Approximately 30% of the protein in cow's milk are a protein called beta-casein. These proteins can be grouped into two types: A1 and A2-type, based on a a single amino acid difference.

It is this difference that causes A1 and A2-type proteins to be digested differently in the stomach.

Some people experience digestive issues when drinking ordinary milk containing A1 protein. a2 Milk® naturally contains only A2-type protein and as a result, some people who find that they experience digestive discomfort with ordinary milk, may be able to enjoy a2 Milk®.*

What's the difference between A1 protein and lactose?

They're both found in milk, but they're very different things. A1 beta-casein is a protein, while lactose is a sugar. Some people are sensitive to one, the other, or both.

If lactose is your concern, we offer a2 Milk® Lactose Free which retains all the delicious taste of a2 Milk® but without lactose and naturally without the A1 protein.

Studies have shown that some people who are lactose maldigesters, including some with clinically diagnosed lactose intolerance, may experience fewer symptoms of digestive discomfort after drinking a2 Milk® than after drinking ordinary cow's milk.*
