The Most Comprehensive Intolerance Testing in the World

The only online test for nearly 600 food and non food items

One of the most popular tests in Europe is now available in the USA and Canada.  Food and non food intolerances affect millions of people everyday.  Every person suffers intolerances (items the body cannot assimilate properly). Symptoms include:

  • Headaches
  • Nausea
  • Bloating
  • Stomach cramps
  • Diarrhea
  • Constipation
  • Fatigue
  • Skin disorders

Missing essential nutrients from your diet also causes illness and disease.  Many companies offer an initial low cost test, their results are always basic, and will not provide you information of what your intolerances are without you having to pay more.  The lab we work with believes that you should get this information at no extra cost.

Why Should I Get Tested?

The leading online test for food and non food intolerancesThe amount of people suffering with intolerances is increasing.  Reports indicate that over a third of the US population are thought to be affected.  As well as causing physical discomfort and misery, symptoms may impact on a person’s mental health and, in many cases, prevent them from living a normal life.  Obtaining an accurate diagnosis of the root cause can be a struggle.   Most tests are currently limited to food items only but more often than not the actual intolerance is related to the chemicals used to process our daily food.  This lab's one-step intolerance test is based on a wide range of both food and non-food items.  Identifying the items to which you are intolerant is vital.  You can then take steps to alter your diet or avoid situations where certain chemicals are commonly found.  Many people believe they may be gluten intolerant or lactose intolerant, but after testing, find it is another substance causing the problems.  There is also another important step that takes you back to living a normal healthy life:

you must ensure your diet includes the correct nutrients or your immune system will be vulnerable to attack and you may continue to suffer problems and symptoms.

That’s why their one-step intolerance test also identifies 80 of the most common nutrients your body requires on a daily basis.

The Test 

The lab we use has developed the most comprehensive intolerance test available in the world.  Using the latest bio-technology, their safe and non-invasive procedure uses a sample of your hair.  Each food, non-food and nutritional item is tested against your sample.

What gets tested:

  • Almost 300 of the most common food items
  • Over 300 non-food items including chemicals used in food processing and packaging

Their innovative one-step intolerance test enables us to produce a comprehensive report, divided into five areas:

  1. The items of food and non-food that you are intolerant to
  2. Where the non-food items (especially the chemicals) are commonly found
  3. The nutrients your body is lacking (optional)
  4. The food items that these nutrients are commonly found and any illnesses or conditions that can occur due to the lack of these nutrients
  5. Guidance on how your individual intolerances can be reduced or even eliminated completely
