Purchased the test intolerance and micronutrition tests as a recommendation from a friend. It was very simple and clear explanation how to do send the sample - just cut a tiny amount of hair, add it inside an envelope, add the printed information page and send it to the given address. I have selected the "fast" - priority - option to receive the results. Sending the sample from Berlin to Lindau and receiving the answer in my email took 3 days. It came as a PDF document with structured form which has been divided into sections for 1. Introduction and explanation to the test 2. Additives 3. Soft drinks 4. Nuts 5. Animal products and other ingredients or materials that people are exposed to every day and might have intolerances without even know. For the micronutrient test, I have received information about vitamin levels, amino acids, enzymes and trace elements - some of whose levels I was surprised to find out how much I was missing. From the information and given example size it was highly elaborative and it felt like a high value for money purchase. Would recommend the service to everyone, especially the ones who wish to know more about their wellbeing and live a healthier lifestyle.
