The a2 Milk® Difference
At The a2 Milk Company A1 protein free milk is what we do.
What is a2 Milk®?
a2 Milk® is 100% natural dairy milk, but with one important difference - a2 Milk® is naturally A1 protein free.
Unlike ordinary dairy milk, a2 Milk® is sourced from cows that naturally produce milk containing only A2-type protein, and no A1.
Cows are specially selected using a simple genetic test.
What is the difference between A1 and A2-type proteins?
Approximately 30% of the proteins in cows’ milk are called beta-casein. These proteins can be grouped into two types: A1 and A2-type based on a slight difference in their amino acid structure.
It is this difference that under normal digestive conditions causes A1 and A2-type proteins to be digested differently in the stomach in some people.
Why recommend a2 Milk®?
Dietary guidelines recommend dairy milk and dairy products as an important source of many nutrients including calcium across life stages1. For example, most Australians consume only about half the recommended quantity of milk products or alternatives1. In some cases, this is due to self-reported milk intolerance and digestive discomfort2.
A growing body of clinical research suggests that for some people, the A1 protein in ordinary dairy milk may be the cause of these digestive issues. a2 Milk® naturally contains only A2-type protein and no A1. Some people who find that they experience digestive discomfort after drinking ordinary dairy milk may be able to consume a2 Milk® and experience less digestive discomfort, meaning more people may be able to enjoy the nutrition and health benefits of dairy milk.
