Is NutriCare | INFINITY DNA-Test useful for Darmgesundheit?

The NutriCare | INFINITY DNA-Test analyzes SNPs for nutrition-related traits, but effect sizes are small and evidence is mostly from GWAS. For gut health specifically, there is no direct evidence in the provided context. The test cannot diagnose intolerances or gut diseases. IgG-based food intolerance tests (like NutriCheck) are not supported by medical guidelines because IgG indicates exposure, not intolerance. For genuine gut issues (bloating, diarrhea, pain), a medical workup with stool analysis or breath tests is more appropriate. The DNA test might theoretically cover SNPs for lactose intolerance (LCT gene) or gluten sensitivity (HLA-DQ), but these are not mentioned in the test description. Conclusion: The test is not useful for gut health; invest in a doctor's consultation instead.
