Is it lactose intolerance or is it A1 protein?

What is A2 milk, and why does it matter?


Some folks in Australia, at the A2 milk company, claim that their A2 milk solves the problem of drinking cow’s milk for those of us who are dairy intolerant. You can read the entire article here.

The claim is that it is not the lactose in cow’s milk that is the problem, but a protein called A1.

In the 1990s, New Zealand-based scientist and entrepreneur Corran McLachlan discovered the A1 and A2 proteins in cow milk, and found that many people who experience symptoms such as upset stomachs after drinking milk are not actually lactose intolerant—they just have trouble digesting A1 protein. This protein is present in some, but not all, cow’s milk.

A1 and A2 are beta caseins.   Those who believe they are lactose intolerant may indeed be intolerant to these beta caseins.  But is this really the case?  There is no scientific proof as of yet that it is.  But, I can say with all honesty, if I could drink cow’s milk again, even in small quantities, I certainly would.

Coconut milk just doesn’t cut it as a stand alone beverage.  I used to love drinking an ice cold glass of milk with cookies or cake.  I have tried doing the same with coconut milk, and I just can’t get it down.  I even tried adding chocolate syrup, to no avail.  I used to drink coconut/almond blend, but even that was tough by itself.  Coconut milk holds up really well in baking and cooking, but I can’t tolerate it by itself.  I have taken to drinking herbal tea with my desserts.

I have found, to my surprise, that I can eat cream.  I used gluten free cream of mushroom soup in my recent green bean casserole.  It had cream in it.  So did the cool whip I put on my gluten free apple pie.  I am now wondering if I can eat sour cream, but I am chicken to try it.  I also wonder if I could drink this A2 milk.

I hope that at some point it will be available here in the U. S.   I doubt they could send a sample.  I have written to several companies recently asking for samples of their products so that I could share reviews with all of you.  I recently received an entire box of snack samples.  But that is for a future blog post.

I will be contacting the company that produces this milk.  I will share my findings with all of you.

Do any of you have thoughts on A2 milk?   Please share your thoughts and comments!

  1. Hiya! I was wondering if lactose free milk is available where you are? It’s very readily available where I live, and yet a lot of other lactose intolerant people I know weren’t even aware it existed. I also don’t know how true this is, but dietitians have previously told me that things like cream, which are very high in fat, tend to be lower in lactose and so are more easily tolerated. I personally have never had any luck with A2 milk. It made me exactly as ill as drinking too much regular milk would. But I have heard of some people who can drink A2, so who knows! Good on you for investigating this!

      Thank you for your comments. Yes we do have lactose free milk but I can’t tolerate it. My issue is whey protein. Not sure why I can eat small amounts of cream but can’t eat cheese.
      I guess everyone will have a different reaction to the A2. Thank you for sharing your experience.

    Ok- this is so ironic! I just bought A2 milk and was thinking about this yesterday. Thanks for the super informative post!

      Hi McKenzie,
      Wow! I must be psychic! Please share your experience with the A2. Also, are you lactose intolerant or dairy intolerant?

        I actually only used it in cooking so far and it worked great!

        I am not, but my husband prefers avoiding whole milk so we try different ones like that! Good so far!
