The a2 Milk Difference

Milk isn’t just milk.  The creamy goodness is a complete protein that provides many essential nutrients such as calcium and vitamin D. Here we’re sharing information on the difference between ordinary cows’ milk and a2 Milk™.

What's the Difference Between Ordinary Cows' Milk and a2 Milk™ ?

Let’s dig into the science. Milk from cows contains ample protein, including casein and whey. Approximately one third of protein in cows’ milk is beta-casein which includes both A1 and A2 beta-casein.

There is a slight difference in how these beta-casein proteins are digested. Published research suggests that A2 protein is easier on digestion and may help some avoid discomfort.

How Do I Find Food Products Containing the A2 Protein?


If you prefer to consume foods made from animals that only produce the A2 protein and no A1, look no further than milk-based products (such as cheese, yogurt, cream or milk) derived from buffalo, goats, sheep, and specific cows, according to Medical News Today. a2 Milk™ is 100% Canadian milk and comes from cows that naturally produce only the A2 protein and no A1.

Does a2 Milk™ remove the A1 Protein?

a2 Milk™ is a naturally occurring cows’ milk and we don't do anything to the cows to get A1-free milk. In fact, all cows originally produced only the A2 protein but a natural genetic mutation occurred thousands of years ago causing the A1 protein to appear. Now, it is a genetic expression like having brown eyes versus blue eyes. We test the cows using a hair on their tail and select cows that naturally produce only the A2 protein type and no A1.

How Do A1 and A2 Proteins Affect Us?

For some people, dairy may be a source of discomfort but they’re not sure why. This often leads people to assume lactose intolerance (without a clinical diagnosis), eliminating cows’ milk from their diets and missing out on important nutrients in the process. In some cases, it may actually be a sensitivity to the protein type that is creating their discomfort. Drinking a2 Milk™ has made it possible for many to love milk again.

If you’re ready to give a2 Milk™ a try, you can find it in your local grocer’s dairy cooler. If you’ve taken a break from dairy, discover the 10 ways to love milk again for a simple way to help you reintroduce milk into your routine!
