“I got the test because I had been feeling brushed off by my doctor. I had been diagnosed with IBS, re-flux and allergies that gave me a range of symptoms, from feeling bloated or hungry, even after a large meal that lead to weight gain to chest and head pains and at its worst, coughing up blood, bleeding out of my nose and blood in my stalls. The doctors were very good at making sure that the condition was not more serious, such as cancer etc. but after that, they were very poor in helping me to manage the symptoms. Experimenting by oneself to figure out what affects the condition is a very long-winded and error prone task. When the symptoms have flared, they took a long time to settle down again and it was never that clear what flared them – was it food, stress or the air that I had breathed recently. After the intolerance test, I got a list of exactly which pollen’s, moulds, and foods I was intolerant to. Very quickly, after cutting everything out on the list, my IBS and re-flux vanished, I have not bled since and I started to lose weight. Happy days. I am very thankful for the test as it gave me exactly the advice that I needed at the time when I needed it.”

My grandson has eczema and I wanted to know what triggered it, I thought my foster son was lactose intolerant, he was and I wondered if I had any intolerances. The results were very concise. As a result of your test, his eczema has really improved and the flare ups are less often and much more minor. My foster son has stopped having tummy aches so that’s great for him and it was a really easy solution.

Nicolette Hughes, United Kingdom

I had a breakout of skin rash on my neck and face and was not getting the help from the GP that I felt was required. The test provided a good level of information and was easy to complete. My condition is improving daily.
