What people say about our TESTS

  • Implementing the changes in my diet suggested by the results of my bio-resonance test had an almost immediate effect. I felt less bloated, had more energy and my guts calmed down and all the pain went. I particularly appreciated the nuances that the test brought up, for instance that the gluten test showed that whilst I shouldn’t eat bread, I could eat wholewheat pasta, so it gave me more dietary options than I as expecting. I also saw that I had been overdoing it on some of my favourite foods (raisins and ginger) but removing them for a few weeks and then re-introducing them in moderation has meant that I don’t suffer ill-effects from them any more.

  • ..... firstly a huge thank you to Annalisa for helping me out in my hour / year of need ! I had been suffering with ongoing stomach issues which no one could put their finger on. After sending my sample away I was quickly sent an extensive list of foods that I was intolerant too and degrees of intolerance. I cut those foods out and followed Annalisa’s advice and I am feeling great and my stomach issues are fully on the mend. Thanks very much.

  • took both wheat and gluten and lactose and dairy sensitivity tests. It has been so interesting to discover specific foods that I can avoid to reduce bloating and fatigue. With some careful planning, I can now enjoy meals that give me energy and help me feel revitalized instead of wanting to go for a nap! Annalisa at Langton Smith gave plenty of welcome advice to help me get my eating habits to work for me.
