MyBody-X angle on DNA Test Genetik

MyBody-X DNA tests are designed for lifestyle and nutrition optimization, not for medical diagnosis. The company explicitly states they work 'ohne medizinische Versprechen' (without medical promises). Effect sizes of genetic variants are generally small and ancestry-specific. These tests cannot diagnose diseases such as celiac disease, lactose intolerance, or nutrient deficiencies – that requires medical evaluation (e.g., tTG-IgA test, breath test, blood work). For athletes, general sports nutrition guidance is often more impactful than DNA-based recommendations. Even for MTHFR variants, folic acid remains adequate per ACMG/CDC guidelines; switching to methylfolate is not proven superior. The evidence is mixed: some associations (e.g., lactase persistence) are well-supported, but translating genotype to phenotype is imprecise. MyBody-X tests may serve as a starting point for healthier habits, but they should never replace professional medical advice. Always consult a doctor for health concerns.
