Customer feedback

The service and advice was useful with my results being explained in detail. I’ve now made some changes to my diet and am seeing the benefit.



Fast results, interesting information. Has given me the guidance I needed to avoid foods that upset me.



I knew that Gluten was a trigger and it hasnt shown on previous blood tests. I'm really happy with the test and information provided.



So many foods and drinks listed that I eat regularly. I'm now working through the list to discover the worst triggers. Thanks for the help!

About The Sensitivity Test

It’s important to check your sensitivities so that you know which foods are causing you serious problems. Our quick procedure starts the moment you make your purchase as we send you the forms you need to fill out. Each instruction is carefully explained, from how to take a hair sample, to how it needs to be packaged (a normal envelope is fine) and then you return it to us in a stamped addressed envelope.

We only take a very small sample of your hair as that gives us the tools we need to test your intolerances. The test results are then produced in an easy to understand form which is split into the different categories of food, non-food, nutrition and metals, depending on your results. We test for an 85% reaction rate as this is the level that will cause a symptom in your body.

Included in your report is an easy to understand introduction written by our nutritionist team which will help you get the most from your test. We also tell you more about each item including where it is found, and a further description so that you can fully remove it from your diet.

We test hair as it’s less invasive than a blood sample, it’s more accurate when sending samples through the post, and allows us to give you fast results.

Stop the symptoms – fast!
