A revelation for
IBS sufferers

Would just like to say “Thank You” 6 years of terrible IBS within 1 week of replacing my milk intake with a2 Milk – I have not had an episode in 5 months!


“Many people who consume A2-only milk generally find it easier to digest and have fewer symptoms”

15% of adults in the UK are diagnosed with IBS. A report published by The Specialist Gastroenterology group of The British Dietetic Association (BDA) recently acknowledged that the A1 protein, commonly found in regular milk, could be to blame for IBS symptoms.

Julie Thompson, registered dietitian with the British Dietetic Association and co-author of the new IBS guidelines comments: “this is a progressive time for research into IBS and the growing evidence around the A1, A2 beta casein proteins and their impact on digestion was deemed important enough to include in the discussion of the BDA’s recent report”.

IBS and A1 protein

In October 2016, The Functional Gut Clinic selected 12 of their patients diagnosed with IBS to participate in a cows’ milk trial to see if milk with only the A2 protein was easier to digest than milk which contained the A1 protein. This trial demonstrated that their issues with dairy could in fact be specific to the A1 milk protein that’s found in regular cows’ milk.

IBS and Lactose Intolerance

Many people say that their IBS symptoms get worse when they have milk and often self-diagnose or consider themselves lactose intolerant. However, according to Ms. Thompson “some people with IBS still report problems on consumption of lactose free milk, suggesting it could be a reaction to the A1 beta-casein protein in this group of individuals. We welcome further research into this topic, specifically in IBS.”

A simple switch to a milk that is free from the A1 protein could help many IBS patients manage their symptoms.

“I have been on a2 for 5 days now and it’s fantastic, I was seeing a dietitian who put me on a lactose free diet because of IBS, I still was suffering, so I came across this a2 milk whilst browsing for an alternative to lacto free, and I’ve felt a difference almost immediately. No more bloating and stopped feeling sick. Great milk, thank you x”

Diet Tips:

1. Many people tell us that switching regular cows’ milk to one that is free-from A1 protein, helps to ease symptoms.

2. Eat fresh meals with whole foods. Ready meals and takeaways can contain ingredients that aggravate IBS symptoms.

3. Avoid fad diets or ‘detoxes’. Your gastric system is already very sensitive. Make one small change at a time.

4. Eat small meals at regular intervals. Small portions cause the stomach to stretch less and digest faster.

5. Reduce the total amount of fat in your meals. Look for foods labelled as ‘low fat’ or ‘0% fat’.

Lifestyle Tips:

1. Slow down! Eating too fast can mean you swallow air, making bloating worse.

2. Exercise can help shift any trapped air which will alleviate some of your bloating.

3. Stress-relieving activities such as yoga, meditation, massages or even a warm bath can be fantastic to calm symptoms down.

If you have been medically diagnosed with any milk intolerance, seek advice from your doctor before use.
