NutriCheck I Unverträglichkeits-Test: can a microbiome test help?

The NutriCheck I Intolerance Test aims to identify food intolerances. A microbiome test can provide insights into gut bacterial composition, but it is not a validated diagnostic tool for classic intolerances like lactose, fructose, or histamine intolerance. These are diagnosed via specific breath tests or elimination diets. A microbiome test may reveal dysbiosis or imbalances that correlate with digestive symptoms, but it cannot directly confirm an intolerance. The evidence for microbiome tests in this context is weak and largely based on marketing claims. Conservative advice: If you suspect an intolerance, a medically supervised test (e.g., lactose H2 breath test) or a controlled elimination diet is more reliable. A microbiome test can be complementary but should not be the sole basis for dietary changes. Be aware of potential false positives/negatives and interpret results with a doctor or dietitian.
