The a2 Milk Difference

Milk isn’t just milk. And some “milk” isn’t even milk at all. The creamy goodness is marketed in many forms, including milk from animals such as cows or goats and an array of milk alternatives made from plants such as almonds or soybeans. Cows’ milk in particular 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 in Nutrition Journal 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, half and half or milk) derived from buffalo, goats, sheep, and specific cows. a2 Milk® is 100% real milk and comes from cows that naturally produce only the A2 protein and no A1. 


If you enjoy experimenting in the kitchen, you can try making your own Homemade butter or Homemade ricotta cheese using a2 Milk®.

Does a2 Milk® Remove the A1 Protein?

No, because it's not necessary. a2 Milk® is a naturally occurring cows’ milk, and we don't do anything to our cows or the milk 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® and using a2 Milk® Half and Half 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. Then, why not make a batch of homemade yogurt or a refreshing smoothie to fit into your naturally healthy lifestyle? Cheers to enjoying milk as part of your everyday nutrition!
