What is a2 Milk®?
a2 Milk® is pure and natural dairy milk. But unlike ordinary dairy milk, a2 Milk® is sourced from cows that have been genetically tested to confirm that they naturally produce milk with only A2-type protein, and no A1.
a2 Milk® has all the goodness of dairy without the A1 protein.
Understanding beta-casein protein in milk
Not all milk is the same. The key difference between a2 Milk® and ordinary cow’s milk lies in the type of beta-casein protein your milk contains.
Dairy milk contains two main groups of proteins: casein and whey. Beta-casein is a form of casein protein that typically makes up about 30% of the total protein content.
30% OF MILK PROTEIN
Beta-casein makes up about one-third of the protein in cow’s milk
12+ GENETIC VARIANTS
At least 12 known variants of beta-casein protein are divided into A1 and A2-types
DIFFERENT EFFECTS
This difference affects how the beta-casein protein is digested
World-leading testing
At The a2 Milk Company™, we test every step of the way - from the cows on our farms to the milk in your glass - so you can trust the purity and quality of every drop. Our testing methods and protocols are expertly designed to deliver world leading accuracy, sensitivity and reproducibility across our global testing labs and partners.

Consumer confidence and trust
As pioneers of the A1 protein free milk category, we have extensive experience in the development and implementation of protein detection tests.
That’s why consumers around the world can always feel confident and trust in the quality and consistency of our products.
Currently, the only international standard relates to testing A1 and A2 beta-casein proteins, published by the Association of Analytical Chemists (AOAC).
