Got a question for us? Well, you’ve come to the right place.


Yes, a2 Milk™ is naturally occurring cows’ milk; it’s not a result of a technological process or genetic engineering. We simply select cows that produce only A2 protein.

This is one question we hear every day.

Lactose intolerance is a sensitivity to the sugar in milks, whilst A1 protein intolerance is a sensitivity to the specific A1 protein, which digests very differently to the A2 protein.

The confusion arises because the symptoms of lactose intolerance and protein intolerance are pretty similar. These symptoms include stomach pain, bloating, wind for some people or other digestive issues.

1 in 5 people in the UK say they have issues with milk but only 1 in 20 have been medically diagnosed with lactose intolerance. As lactose intolerance is more widely known, they assume that it's this sugar that is causing them issues, rather the protein. However, for some people the problem isn't lactose at all – it is in fact the A1 protein that could be the issue.

Milk allergy is an abnormal response by the body's immune system to milk and products containing milk whereas an intolerance to milk doesn't involve the immune system. If you'd like to read more about the differences between the two, please click here.

Yes indeed; a2 Milk™ contains exactly the same amount of nutrients, calcium, protein, vitamins and fat as normal milk, potentially making it a perfect solution if you and your family struggle to digest normal milk.

Doctors recommend whole milk for children over 12 months and semi skimmed milk, for children over the age of two.

However, children with a medically diagnosed allergy to cows' milk protein or lactose should not drink a2 Milk™, or any other natural cows' milk.

The best way to check to see if you have an intolerance to food is to keep a food and symptoms diary. If you can link milk cow's milk to digestive issues then simply replace it with a2 Milk™. If your symptoms disappear then it's likely that you have an A1 protein intolerance. Click here to download a food and symptoms diary.

Our farmers ensure that their cows are treated in exactly the same way in which A1 cows are treated.

Our cows are just the same as any other cow, they just produce milk with the A2 protein. They haven't been tampered with or modified in any way. All we do is separate out and milk the A2-certified cows from the rest of the herd to guarantee pure fresh a2 Milk™.

If you are reintroducing milk into your diet, it's important that you do it gradually.

To begin with, consume a small quantity, for instance in a cup of tea, and look out for typical symptoms developing over the next 24 hours. If nothing happens, consume a second quantity of milk the following day and assess again for symptoms. If symptoms persist, continued avoidance of milk is required.

If you have had a diagnosed milk allergy it's important that you only introduce cows' milk on the advice of a health care professional.

a2 Milk™ contains the same amount of lactose as normal milk, so it's not a solution to medically diagnosed lactose intolerance. However, if you haven't been medically diagnosed, a2 Milk™ may well be a good choice for you.

Milk and milk intolerance can cause a variety of different concerns and problems. 90% of those with a milk intolerance have digestive issues, but others report skin irritation and excess mucus build up.

In the 1990s New Zealand based scientist Dr. Corran McLachlan researched why more and more people were having adverse reactions to drinking regular milk. He uncovered that not all cows' milk is the same and there are in fact 2 types of cows within cow herds, A1 cows and A2 cows. Dr. McLachlan found that normal milk contains different proteins including A1 and A2. As his research progressed, he observed that the A1 protein in 'normal' milk seemed to cause some people to experience side effects (such as bloating). On the back of this discovery, he set up The a2 Milk Company to pioneer understanding in this area.

British A2-certified farms. We have 20 farms certified to provide a2 Milk ™ throughout Shropshire, Cheshire and North Wales. Not only do we carefully select our A2 cows we also carefully select our farmers. There is a rigorous process to become an A2-certified farm and as a result we support our farmers through their journey to build up our British A2 cow herds. Meet our farmers here.

As part of Dr. McLachlan's research he discovered that cow herds contain 2 types of cow beyond different breeds of cows. These cows can be referred to as A1 cows and A2 cows. A1 cows produce milk that always contains the A1 protein – either on its own or mixed with the A2 protein; whereas A2 cows just produce milk containing only the A2 protein and no A1.

After Dr. McLachlan found this out he developed a simple DNA test to identify the A2 cows allowing farmers to select out the A2 cows from their herds. This test isn't painful or invasive for the cows in any way, a sample of hair from the cow's tail is taken and tested to find out if it's an A2 cow.

Depending on your level of milk intolerance you may feel the difference in a matter of hours after consuming a2 Milk™. However, we recommend you consume it for a minimum of two weeks to feel the full benefits.

Yes, you can freeze a2 Milk™ just like you use any other milk.

Both semi skimmed and whole a2 Milk™ are available in 1 litre bottles from selected Sainsbury's, Waitrose, Tesco and Morrisons stores. a2 Milk™ can be found in the chilled specialty milk section.
