Excellent service. Very quick turnaround!!
Super value for money! Recommend to anyone having daily niggles. Certainly helped me! Thanks
A very detailed report via email. Would recommend!!
Why have I not found this sooner! Wow! Cannot believe the difference this has made to everything - from my mood swings, my energy, my skin, I just feel so much fresher. Clearly certain things did not agree with me at all and after cutting…
Interesting and enlightening results.
This testing was a kind of life change for me. I’ve suffered for years not realizing what I was eating was my trigger to these issues. Avoiding certain foods has made my life much more comfortable. Thank you
Great customer service. Very prompt and sorted an issue quickly. Really pleased with my results too.
What a great report! Sent within a week via email. I was really impressed with all the information I got and the amount of information too. Thank you for helping me figure out what food (and non-food) items to stay away from! Looking forward to…
Easy and quick results.
Been meaning to take a test like this for a while now. So happy that I did. I feel so much better and have so much more energy. Great value for money
I was a little sceptical taking this test but so pleased I did. The information this test gives you is impressive. For the money you pay you get so much advice and information which has now helped me (dare I say) cure my long-term stomach…
Most common questions
Do you send a test kit?
No. It’s a digital service: everything you need arrives by email, so you can post your sample the same day you order.
How much hair do you need?
4–5 strands, cut close to the scalp. Coloured or treated hair is fine.
What’s the difference between an allergy and an intolerance?
Allergies involve the immune system and can be serious, so they’re diagnosed medically. Intolerances and sensitivities tend to cause slower, milder symptoms such as bloating or tiredness. This test is a starting point for exploring those, not an allergy test.
How long do results take?
Within 3–5 working days of your sample arriving at our lab, or within 48 working hours if you add priority results.
Can children take the test?
Yes, from age 6. Under-18s need a parent or guardian to order for them.
Does hair dye affect results?
No. Coloured, dyed and treated hair are all fine.
What do I do with my results?
Use your elimination guide: remove the high-response items for 6–8 weeks, then reintroduce them one at a time while tracking how you feel.
What if I’m not happy?
You’re covered by our 30-day money-back guarantee. Email us within 30 days of your order and we’ll refund you in full.
