Frequently Asked Questions

We’ve compiled a list of common questions and answers to help you better understand food intolerances and how our testing can help. If you have additional questions or concerns, please don’t hesitate to reach out to our team. We’re here to support you on your journey to better health and wellbeing.

What is a food intolerance test, and how does it work?
A food intolerance test is a diagnostic tool that helps identify food and non food items that may be a negative reaction in your body. Using our state of the art technology we can identify any factors which may be causing symptoms like bloating, headaches, and fatigue.

Here at US Food Intolerance we calculate our success levels by using our formula which incorporates satisfaction levels, refund rate and feedback from you the customer and other health professionals who use the service within their health companies. Our current customer satisfaction score is 9.7 out of 10.

Please note with US Food Intolerance we do not supply a sample testing kit. Once your order is confirmed we will send you your personal account login details via email, advising of your next steps.

As a health and wellness company this virtual method is the best way to help combat the environmental issues we are seeing today.

At US Food Intolerance we have created our test to ensure all relevant foods and food groups are available to be tested. Unlike other test providers we pride ourselves on “no fillers”
No, a food intolerance test cannot diagnose a food allergy. Food allergies involve a different immune system response and can be life-threatening. If you suspect you have a food allergy, it’s important to see a healthcare provider for proper diagnosis and treatment.
Your results from our tests are to be used as a stepping stone on your health journey. Eliminating the trigger foods we identify will help you gain clarity on the next steps to feeling better.
Children can take the test, and due to its less invasive nature it can provide an insight into any current digestive issues. Please note however, due to the quick evolving nature of a child’s growth and development the results can change quickly. For this reason we do not test children under 6 years old. We would never substitute our test for the information and support provided from your local G.P
If you are experiencing persistent symptoms like bloating, fatigue, headaches, or skin irritation, and suspect that food may be contributing to these symptoms, a food intolerance test will be helpful.
