What is Food Sensitivity?

Food Sensitivity can be associated with difficulty digesting food items like dairy or gluten causing unpleasant physical reactions from the body. Food sensitivities’ most common symptoms include bloating and stomach pain, both occurring within several hours of eating. Other symptoms include wind (bloating), diarrhea, skin rashes, and itching.

If you regularly experience the above symptoms, you may have a food sensitivity. We help identify food sensitivities.

What’s included in my test?

The test includes one intolerance test, one nutritional deficiency test, and one metal test. Your intolerance test results include all items that have shown a score of 85% and higher. After completing thousands of tests, we now know that 85% is the turning point where symptoms begin to develop into an allergy/intolerance.

What should I do with my test results?

To increase your quality of life you should, over 4–6 weeks, completely exclude the items your body is intolerant to. During this time your body will get the peace it needs to repair itself. After this period you can either take a new test to be sure your body is “ready” or, gradually and in small increments reintroduce the items to see if there is any reaction. As for the nutrients you may be missing, we recommend that you follow our dietary guidelines and make sure that your body gets the nutrients it needs to stay healthy and strong.

How do your tests compare to blood samples?

In addition to being less invasive and significantly cheaper, your last meal may affect the results of a blood sample, whereas a hair sample has the information stored for a longer period and reflects a wider time frame.

How do I take a hair sample?

The safest way to take a hair sample is by asking someone to help you. First, brush your hair upwards to get easy access to the hair roots and the back of your head. Hold a small amount of hair between your finger and thumb, and cut the hair as close to the scalp as possible (without pulling any blood). If you do not have someone who can help you, please use a mirror to avoid accidentally hurting yourself.

How do I submit my hair sample?

When your order is completed, instructions will be sent to your email along with your receipt (i.e. we will not send test kits). Simply take 4–5 hair strands from your scalp, put them in an envelope along with a completed form (instructions are emailed post order).

My hair is dyed. Will this affect the results?

No, we test the composition of the hair sample, so the hair dye will not affect your test results.

How much hair do I need to submit?

Only a small amount; 5 individual strands. We don’t require clumps of hair.

What’s the difference between allergy, hypersensitivity, and intolerance?

There is quite a big difference between being allergic, intolerant, or hypersensitive to a substance however, the symptoms often resemble each other. For those who get ill from their diet, it may feel equally bad. The devil is known by many names, some might say. Our test results will shed a light on what intolerances you might have, in other words, which ingredients to avoid. An intolerance may pass after a while, while an allergy lasts for life.

Can children take the test?

Unfortunately, we don’t recommend the test for anyone below the age of 6. Younger children have not yet built up their tolerance levels, and this can give false results in the lab.

Can animals/pets take the test?

Yes. Pets can suffer from similar intolerances to humans. We offer a Pet Intolerance Test for cats and dogs with 60 checks for common pet food brands, in addition to environmental factors.

How do I purchase an intolerance test from you?

Tests can be easily ordered on our website. Should you have further questions, please don’t hesitate to email us.

Fascinating and concise answers I had been waiting for. Customer service team highly efficient particularly Lillie who was of great help to myself. Outstanding service. Thankyou

List Kerry

I have been unwell for several months with no reason and decided to do an intolerance test to reach some answers. I received my results very quickly and it flagged up several intolerances that I would never have thought to cut out, but a few days of cutting them out and I am already feeling better. Customer service was great too, very fast when I had an inquiry and very friendly. Would recommend.

Elizabeth

This testing was a kind of life change for me. I’ve suffered for years not realising what I was eating was my trigger to these issues. Avoiding certain foods has made my life much more comfortable. Thank you

Kipper

I would really recommend this test to everybody!! You get results very quickly in a concise and easy to understand document.

Siofra

Salmon came up on my test, I have eliminated this from my diet and I cannot believe how good I feel, So much more energy and less lethargic, thank you so much!

Becky B

I had some desperate health issues but after doing the test and avoiding certain foods I cannot believe how good I am feeling!

Jeremy N

I am not one for leaving reviews but I am so pleased with my results. After years of suffering with inflamed joints my test results showed I was intolerant to many varieties of nuts. I have cut these out and they have improved dramatically! Easy to use and great feedback through email. The info I received was very thorough and easy to read through. I cannot thank you enough!

Asha

Very easy to order and use. Quick response, no frills testing with great informative results. Thanks so much. I am now thinking of ordering one for all the family!
