Intolerance Testing


Do you or your pet suffer from the following?

Headaches, nausea, bloating, stomach cramps, diarrhoea, constipation, fatigue, skin disorders, brain fog or lethargy.

We offer the most comprehensive allergy tests available. Using the latest bio technology, our safe and non-invasive procedure uses a single sample of your hair to run the tests. After producing a sample of your hair and making a payment, we will email you your test results as soon as they are available (usually between 7-10 days).

Often the skin conditions we think are caused by more serious underlying problems are easily rectified with a change in diet. Many of our clients have achieved fantastic results for their skin by having the Intolerance and Nutrition tests and making small changes as a consequence.















We currently have three tests that each benefit you in a different way:

Typically we suggest that the Intolerance and Nutrition test are taken together as it provides a more comprehensive list that could benefit you the most. Combining all 3 tests, however, will provide you with the most information to make the necessary small changes in your life. 

Intolerance Test 


Testing your sample against 600 different food and non-food items to see what could be causing you issues.

Your results will have a comprehensive report of the items of food and non-food that you are intolerant to, as well as where they are most commonly found.

Once you have received your test, we suggest that you try and eliminate the food items that are shown on your results. It is recommended that you try to eliminate the items for at least 2 weeks, but preferably 4. Try to eliminate them all at the same time, understandably this could be a daunting task, but it will allow you to see results fast. After the 4 weeks, you should try and add the items back into your diet one by one. Adding them back in one by one is essential as intolerances don't always show symptoms straight away - it could be a few hours before you see any symptoms. We suggest that you keep a diary. Most of the time an intolerance will disappear but there are occasions when your body simply won’t want to accept something back into the body and so this will become a lifetime intolerance. Although this may seem difficult to deal with, it is something that you will get used to fairly quickly, especially if you aren’t suffering the associated symptoms anymore.


Nutritional Deficiency Test 

We test your sample to find out what you’re lacking in out of a list of 80 nutrients. 

We only show the nutrients that are likely to be causing you the most issues in your life. The nutrients that are shown as deficient in your system can easily be improved. Simply try and add in one or two of the recommended food items to your diet each day. Although it may be easier to use a vitamin supplement, it is always better to get your nutrients from a fresh source, as this will enter your body much faster.


Metal Toxicity Test

Testing against 24 different metals of which you could be consuming or living near and might be causing you irritation. After more than 12 months of development, we are pleased to say that we can offer the Metal Toxicity test at our clinic. We are all aware that what we eat and drink contains a certain amount of metal contamination. Metals can have a large effect on our daily lives, and we often don’t realise how much we are consuming/ allowing ourselves to come into contact with.

After many years of not knowing what is causing my allergies I have received a very detailed report that pinpoint food allergies, metal allergies and environmental allergies. Amazing! A life changing treatment. Thank you BodhiZen.

I had an Intolerance test done for my daughter who suffers with terrible Asthma.  I provided the sample and the results were back in 7 days, I was absolutely dumbfounded at amount of stuff my daughter was intolerant to and instantly went in to crazy mom panic mode, Amy and Zoe instantly reassured me that my daughter's condition could be managed if changes were put in place and reassured me not to panic.


Any questions or concerns I've had have been dealt with in professional manner. Zoe and the team at BodhiZen have given me more help and support than I have ever had from my team of doctors who I've been fighting with for years with regards to my daughter.


 I've implemented changes to my daughters diet and I can already see a vast improvement in her health in a few short weeks.  I can't recommend BodhiZen highly enough, wonderful people, wonderful place and a wonderful help.  Thank you so much for everything you've helped me with so far and are continuing to help me with.

Kurt's Story


Kurt, 6, was diagnosed with psoriasis in March 2014.

"We didn’t know what it was at first, and one doctor suspected a viral eczema.  We saw an allergist, two paediatricians, and a dermatologist.  During this time it continued to escalate.  We finally requested a biopsy and found that it was psoriasis. We later discovered that psoriasis runs on both sides of the family.

We were prescribed many different steroid creams (two for his hair, three for his skin), as well as oral steroids.  We were spending about $90 a month on steroids, with insurance.


The steroids made Kurt feel very angry and emotional.  His skin only responded to one of the steroid creams, but it was so dangerous that he had to be monitored every couple of days to make sure his skin wasn’t thinning too much.  I tried some more natural remedies, since I didn’t like him being on so many steroids, but they did not help either.


Last summer I started an elimination diet. Because we didn’t know what was causing the issue, the things we eliminated were a shot in the dark. Now that we have his results, it turns out that only one of the many foods we eliminated was something he shouldn’t have had (bell peppers).  We did sun therapy every day over the summer. When he started back to school in August, he was off numerous foods, but his skin was flaring so badly that he started to feel sad every day because other kids were asking about it.  He had trouble sleeping at night, because it would itch and burn so badly (sometimes he scratched until it bled).


I started looking online for a place to have food intolerance testing done, since I couldn’t seem to convince any of his specialists to order the test. That is when I found The Intolerance Testing Group. Once we got the results back, we took him off all the foods on the list. T tests also showed a high build-up of yeast in his system. We took him off all yeast, and then started using some natural methods to help with his digestive health (aloe Vera, caprylic acid, coconut water, probiotics).  I took him off all steroids, and started using an organic castor oil on his skin.


Within a week we started to see a difference.  The spots of psoriasis were started to turn white in the centre.  With the steroids, they healed from the outside in, but with the dietary changes they were healing from the inside out.

I suspect some of the big irritants for Kurt were the dairy and chocolate.  His skin is cleared up now (you can just see white spots where the psoriasis used to be), and we have slowly lethim start having trace amounts of some of the things on the list (like onion powder or sunflower oil that is mixed in with other foods). We plan to keep him off most of the foods on the list from here on. When Kurt goes to a birthday party, he takes his own cupcakes that don’t have any milk. He keeps a bag of special snacks at school for parties there. And on Halloween, he traded all his chocolate candy for a yo yo that he wanted from the store. Because he is so happy to have clear skin that doesn’t itch and burn, he doesn’t mind having to make a few sacrifices.

Michelle's Story

I haven’t always had problem skin; it only seemed to develop once I hit my twenties.

I tried absolutely everything to treat the acne: antibiotics, laser treatment, natural remedies, chemical treatments and microdermabrasion. Unfortunately, none of these things seems to have much of an effect and only left me more and more frustrated.

A friend told me about The Intolerance Testing Group, as she had been tested and lost 40lbs after eliminating her problem foods. I was sceptical at first as I had never heard of this type of testing before. The company offers a full money back guarantee, so I figured I had nothing to lose.

The ordering process was quick and simple and the fact that you download the test submission form means you can send your sample in the mail the same day. This really appealed to me because I was eager to get my results as quickly as possible. I received my results within 7 days of my sample arriving at the testing facility.

The recommendation from the company is to eliminate all items in my report for a minimum of four weeks. This was a challenge as many of the items in my report were my favourite foods!

After two weeks on the elimination diet my skin started to feel less greasy and angry. By the end of the four weeks I could not believe the difference when looking back at old pictures of myself! My skin looked almost ‘normal’! All these years I’ve been trying to treat the surface of the skin and it didn’t even occur to me that the root cause may be what I’m putting into my body. I feel so much more comfortable in my own skin and would recommend the test to anyone suffering from skin conditions, especially acne.

I am going to continue with eliminating the offending foods and plan on taking the test again in six months.
