I was a bit sceptical at first about completing an intolerance test, but as soon as I decided to try Test My Food Sensitivity, it was one of the best decisions I’ve made. I received my results very quickly and it was fascinating and somewhat surprising to find out my intolerances. Since excluding all intolerances from my diet, it has been a shock and most of all, a relief to see how quickly my symptoms have been alleviated. For the first time in years I have been able to enjoy food without getting constant stomach pains and nausea, and it has felt empowering to regain control over my health. It can seem a bit daunting at first to transform your diet and cut out foods you’re so familiar with, but the nutritional support at Test My Food Sensitivity was super helpful and helped me clarify foods I can and can’t eat and if it is ok to reintroduce them into my diet at a later stage. It feels good to know I have this knowledge about my body forever and I can optimize my health as a result. Massive thumbs up and would encourage anyone to try it for yourself!

Easy test to take and return with clear instructions. The report that came back was far more detailed than expected and highlighted some areas that I had not realised. It was good value for money in my view.

A convenient first step to identify food sensitivities from home. I ordered it for my sister, who has many food allergies. Just be sure to discuss the results with your doctor for a clear action plan. Great little kit!
