Our tests use non-invasive sensitivity (Bioresonance) testing, using a small hair sample to test for 1600 triggers.
Your personalised report will be sent to your email inbox 5-7 days of our facilities receiving your sample.
Rather than needing to spend up to £200+ for a traditional blood test, our sensitivity tests are significantly cheaper.
After receiving your results you’ll know what triggers to avoid, and you'll be able to start changing your diet and lifestyle.
Food sensitivities can be the cause of a variety of health issues including headaches, irritable bowel syndrome and fatigue and even a variety of undiscovered symptoms. Our comprehensive sensitivity tests can quickly help you understand more about possible trigger items.
We have helped people with:
And many more symptoms.
