Now Discover Your Intolerances…

The Fast And Easy Way
Why suffer in silence? Are you one of those people who accept living with a condition that blights your everyday life? But Why? Don’t you realize that you don’t have to live with the pain or discomfort your condition brings you? If we can help you pinpoint the cause (so you can avoid it) your life will change forever. Freedom and happiness await. . .

If you’re affected by any of the conditions below then you need an intolerance test. . .
Plus skin rashes, constipation, and other irritable, uncomfortable, and embarrassing conditions.

Discovering your body’s intolerances couldn’t be easier.

Buy a test at our store and receive our instructions via email moments later.

These instructions will guide you on how to take your sample and where to send it.

Within three days of receiving your hair sample, you will receive a list of foods you should avoid.

These will be foods we have classed as having an 85% or greater chance of being the problem food for you.

The list may be a few items or as many as 20. This will give you a great head start for getting to the bottom of your pain.

Cut out these foods for six weeks, keep a food diary, and start your road to recovery.
Without An Intolerance Test
You Might NEVER Know The
Truth About Your Condition
Whatever your intolerance is, we will find it and pinpoint it so you can avoid it in the future. It’s as simple as that.

Most of the conditions we mention can be associated with a particular food or drink you consume. Getting better is simply a matter of avoiding foods that make you feel unwell.

Intolerance Lab is the key to getting your life back and enjoying the things people take for granted.

Without an intolerance test this can be a tough task of trial and error. Painful blood tests cannot accurately reveal a particular food intolerance. Doctors won’t give out tests at the NHS due to cost restraints.

So take the initiative and get tested yourself.

Our tests are accurate and guaranteed, so you have nothing to lose.

Still not sure if our thorough testing process will work for you? Well, you don’t have to take our word for how successful our full testing service is.

Here’s what some of our very satisfied customers are saying about Intolerance Lab:

Effortless and effective
by KP on 10th June, 2020

I must admit I was sceptical, but
thought, why the hell not lets give this a
go. The entire process was effortless,
easy and the results came back quickly.
I was intolerant to Oats and having cut
them out entirely it has made a huge
difference to my psoriasis. Amazing
how a few hair strands can give such
accurate results. Highly recommend
using Intolerancelab

Excellent service
by Gina suzette 16 August

Excellent service. I had struggled for ages with stomach issues and NHS columns find anything wrong so decided to c if it was an intolerance. Sent a sample off and got the results back really quickly. I decided to cut out all the main culprits on the list for 6 weeks then reintroduced them slowly. It wasn’t easy but I no longer have any issues and now know what each ingredient does to me so can choose to eat it or not x would definitely recommend x

by Lavish Luxuries 14 August

I was initially skeptical but after actually removing the many items on my list, my stomach feels so much better. I always thought it was normal to feel bloated/gassy after eating but it's not. The excess water weight has fallen off and my figure is so much better and all it took was cutting out foods I don't react well with.

I highly recommend taking this test
by Wendy Boyd 18 July

I highly recommend taking this test. I discovered intolerances I would never have thought of and since removing them from my diet I have felt so much better

Life Changing
by Amber Verity Williams 10 July

The process was quick and easy. All questions were answered really quickly. My intolerance list is long but after cutting out those foods my IBS has gone, I have more energy and I’ve lost weight. I really recommend this for anyone struggling with stomach upset.

by Renee Mcdermott 2 July

I was very sceptical at first but after getting my report things made sense I always get blisters on my hands when gardening and found out I react to 2 grasses. also I get a lot of indigestion but taking notice of the report this does not happen anymore. This has changed my life well worth doing.

Allergy and intolerance are often confused, or thought of as similar conditions, when in reality they are very different. Allergy is an immediate, sometimes dangerous or life-threatening reaction to a food or drink. This is often present from a young age and always involves the antibody type IgE. Intolerance can be developed later in life and takes longer for symptoms to present themselves, making it more difficult to pinpoint the culprit food(s). Testing can be beneficial to discover the trigger foods and drinks quicker. With suspected food allergy, always seek profesional medical help.
Some Health Insurance Providers will cover the costs. Contact your provider for more info.
We test for over 350 types of food, including wheat, eggs, nuts, etc. We also test for over 350 non-food items, like pet hair pollen and detergents. If you need a full list, get in touch and we can get you one.
We dont test anybody under the age of six.
Optimum nutrition during pregnancy and breastfeeding is vital for mother and child. To reduce any possible risk to the mother or baby, it’s Intolerance Lab’s protocol not to offer tests, advice or lifestyle changes during pregnancy and/or breastfeeding.
The tests are as painful as plucking a hair from your body..
Your hair does not have to come from your head. It can come from your leg, arm, or even chest.
This will not have any effect on the results.
No. Our tests examine your hair at the cellular level, so there’s no need for you to have been eating your trigger foods recently. They will still be found by our testing equipment.
These two tests are very different in what is tested, the process and the results. A blood test checks for IgE-mediated allergies and will only produce results listing reactions in the immunoglobulin system (these are estimated at only 2% of all allergies). Our hair sample test examines changes at the cellular level because the latest science shows that up to 43% of allergies are in fact a reaction in T cells. The two tests measure totally different reactions and will produce totally different results.
We only offer hair sampling here at Intolerance Lab. Currently, the main way to identify the two types of allergies (IgE and Non-IgE) is on the reaction time from consuming or being in contact with the item. If you notice a reaction that is almost instant or within two hours (max), you would normally consult with your GP and he or she might consider a blood test. These are normally essential for more serious allergies—which, fortunately, only account for 2% of all allergies. If your reaction time is slower or you are unable to identify the link between your symptoms then it is more than likely you have a non IgE mediated allergy. In this instance, we would recommend our hair based non IgE mediated allergy test.
