Myths vs facts: Nährstoffcheck and gut health

The MyBody-X Nährstoffcheck (nutrient check) and gut health are two separate product categories often marketed with exaggerated claims. The nutrient check analyzes biomarkers from blood or saliva to detect deficiencies – this can be useful, but interpretation depends heavily on individual physiology. A pure DNA test for nutrients (e.g., MTHFR) has only small effect sizes and does not replace blood work. Regarding gut health: MyBody-X does not offer a validated microbiome test; their 'food sensitivity' tests lack scientific backing and may lead to unnecessary dietary restrictions. Fact: Real benefit for gut health comes only from clinically validated stool tests (e.g., for inflammation markers or pathogens) combined with medical advice. Myths: 'A nutrient check tells me exactly what to eat' – no, it only provides hints. 'DNA tests optimize my gut flora' – no, genetics play a minor role. Bottom line: These tests can be used as inspiration, but not as medical diagnostics. Evidence: marketing/weak. Safety note: For serious GI issues, always consult a doctor.
