Sound familiar?
You’ve cut out dairy, then gluten, then sugar, and you’re still guessing.
Some days you’re fine. Others you’re bloated by lunchtime and don’t know why.
You’ve been told it’s probably nothing, but it doesn’t feel like nothing.
You’d just like a sensible place to start.
You don’t need another guess. You need a starting point, a plan you can actually follow, and someone to ask when you’re not sure. That’s what we’re here for.

A general comparison with typical kit-based intolerance tests, not any particular company. Services vary, so check the details of any test you’re considering. Allergies and coeliac disease need medical testing through your GP.

What your report can and can’t tell you
We test your hair sample against each item using bioresonance, a complementary (CAM) method. Your report lists the items that showed the strongest response, so you know where to start an elimination diet.
It is not a medical diagnosis. It does not test for allergies, coeliac disease or lactose intolerance, which are diagnosed medically.
- Items to explore: high, medium and low response, grouped by food type.
- Elimination plan: a 6–8 week plan to remove, then reintroduce, one item at a time.
- Food diary: a printable diary to track meals and how you feel.
- Real people, not bots: questions about your report answered by our UK team, usually within the hour on weekdays.
For cats and dogs
Testing a cat or dog?
Itchy, unsettled or off their food? The same simple, digital process works for your pet. Brush or snip a little hair and get a report on 300 to 700 food and environmental items to talk through with your vet.

Rated 4.9 out of 5 in 30 reviews left on our website
The number of items covered is impressive and the results came back quickly. A couple of sensitivities surprised me, so I’m working through a proper elimination now to see how I respond. It’s been useful for direction rather than quick…
I wanted the full picture rather than testing a small list of foods, and I’ve dealt with bloating and brain fog for a long time and felt like I was just guessing. The emailed report was detailed (I had to…
I already eat quite clean, so the additives and environmental section was the biggest eye opener for me. Results were easy to access and arrived faster than expected. It hasn’t solved everything overnight, but I feel more confident about what…
I train quite a lot but was struggling with low energy and random stomach issues. The test covered everything in one go rather than doing multiple smaller tests. A few sensitivities came up that I honestly hadn’t considered. I’ve adjusted…
I’d tried eliminating dairy and gluten before with mixed results. My results highlighted some additives I hadn’t even thought about. Not everything matched what I assumed, but it’s helped me approach changes more logically instead of guessing. Overall happy with…
I decided to test after months of feeling sluggish and not really knowing why. The testing process was simple and results came back quicker than I expected. The report is detailed, maybe a bit overwhelming at first, but once broken…

Questions
Do you send a test kit?
No, and that’s on purpose. Everything you need arrives by email, so you can post your sample the same day you order rather than waiting for a kit.
How much hair do you need?
4–5 strands, cut close to the scalp. Coloured or treated hair is fine.
Is this an allergy test?
No. It’s an intolerance and sensitivity test. Allergies, coeliac disease and lactose intolerance are diagnosed medically, so speak to your GP about those.
Who can take the test?
Adults and children aged 6 and over. Under-18s need a parent or guardian to order for them. We also offer separate tests for cats and dogs.
