natasha testimonial image - Test Your Intolerance Homepage

“Since excluding all intolerances from my diet, it has been a shock and most of all, a relief to see how quickly my symptoms have been alleviated. For the first time in years I have been able to enjoy food without getting constant stomach pains and nausea, and it has felt empowering to regain control over my health.”

“A friend suggested trying one of these tests from Test your intolerance. I was very doubtful but thought I would give it a go, it was cheap and easy to give a sample. I got my results really quickly and I noticed it said Dairy which i cut out. Feel great!”

testimonial 2 - Test Your Intolerance Homepage

“My eyes were no longer twitching and heavy all day. I no longer felt exhausted all day long. Since I’ve given it up I can now feel the difference almost immediately when I eat it or accidentally miss it in ingredients (it’s literally in EVERYTHING). It’s bizarre. People think I’m crazy but I don’t care!”

“Test your intolerance is the business, seriously. It’s cheap, easy to use and quite frankly brilliant. You’ll find the information that comes back to be really interesting and helpful, and you’ll start to feel a lot better once you follow the advice. I’m so glad I did this, so five stars for TYI”

testimonial 3 - Test Your Intolerance Homepage

“I ordered an allergy test for my mother who is 71 as of today, she’s been having some stomach issues and wanted to find out exactly what was wrong, the doctors couldn’t tell her. Now my mom can make those subtle food changes and have a much happier stomach and not be questioning everything she eats. A huge thank you.”

“I bought a test for my daughter as she always seemed to be lacking in energy. The report was easy to read and we went through it. Although many of the items weren’t major things in our diet, I noticed that it highlighted sugar, I had always thought she consumed too much sugar. My daughter agreed to reduce it and we changed her snacks etc and cut back the fizzy drinks.”

“If you are looking for a intolerance test that works you’ve found it! I’m really impressed with what Test Your Intolerance told me and the price is great too. The kit came quickly and I found it easy to use and when the results come back they were really cool, so it’s five stars from me.”
