Symptoms of a Food Allergy or Intolerance.

If you suspect you have a food intolerance or allergy, then you’ll want to understand what it’s doing to your body and whether your symptoms are related to your allergy or intolerance. There are some symptoms which are very common to food allergies and/or intolerances, and some which can be a sign of many different conditions — making it all the more important to truly identify the root cause.

Are you experiencing these symptoms regularly? Then it is likely time to confirm your suspicions with one of our tests. We offer both scientifically validated blood testing & bioresonance hair testing to suit all needs and budgets.

Blood Tests

Our scientifically validated blood tests can help you accurately identify the substances which are causing your problematic symptoms. Using just a small blood sample we can help you identify both your allergies & intolerances. We test for the most common sensitivities, making it highly likely we will get to the root of your problem. 

Hair Tests

We use bioresonance hair testing to assess just a few strands of hair against up to 975 different sensitivity items. As well as assessing your sensitivities against food items we assess your metal toxicity levels, non-food sensitivities and nutrient deficiencies to help you get a complete picture of your current state of health.
