I have a high intolerance to hazelnuts, apples and celeriac. There are still plenty of additional substances that I react extremely to! Nothing of these things were listed in my results... instead of these I found food from which I can say for sure that I tolerate them or that I have never eaten. You'd almost think I got another person's test results.... The processing took 4 weeks and not - as indicated on the website - 7-10 days. Waisted money and very disappointed :-((((

Excellent service with handful support.

Accurate testing by a friendly company. I spoke to the nutritionist afterwards who gave me further advice and it was really beneficial. Love it.

A great, easy to understand test. It helped me to undestand what I need to eat and what I need to avoid. Customer service asked me to leave a review as my test went well.

I sent my hair samples out twice (under two different names) within a month of each other and got two COMPLETELY DIFFERENT results. I didn't change my diet within that time frame either, which tells me that these test results are extremely unscientific and random.

They only report on things over 85% - worth paying more for a better testing provider.

The live chat team were so helpful and explained everything to me clearly before ordering. My results came quickly and were easy to understand. I'll definitely be recommending their service to my friends and family.

I’ve had a fab experience with Test Your Intolerance! The customer service team were very helpful and offered me the perfect advice! Thanks!

I have anaphylaxtic shock to walnuts and penicillin neither of which they picked up. Like others they suggested I was allergic to foods i have never eaten! Not impressed.

Not even 1 star. This company is a complete joke and absolutely not to be trusted. I received test results that said I was deficient in alcohol (?!) so emailed to query on several occasions spanning 7 months and have been completely ignored. When I finally managed to speak to someone on the online chat facility they refused to give me any complaints procedure other than to email the same address that just never responds. Coincidencely the same email address to contact for a refund which they’ve now said I’m no longer eligible for due to them ignoring my emails. A total scam. Do not give this company your money!
