Ellipse 1cows_careers_thea2milk.pngEllipse 2

a2 Milk® is 100% real milk from cows that naturally produce only the A2 protein and no A1. Published research suggests a2 Milk is easier on digestion and may help some avoid discomfort.

Plus, it has the same nutrition and creamy, delicious taste you would expect, since it is real milk!

What is the difference between A1 and A2 protein types?

All cows originally produced only the A2 protein, but a natural change occurred over a thousand years ago, which cause the A1 protein to appear as a genetic variation. Today, most milk comes from cows that produce both A1 and A2 protein in their milk, but a2 Milk® comes from cows that only produce A2 protein.
