Is INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch useful for Darmgesundheit?

The INFINITY DNA-Test including a 28-day plan and recipe book is marketed for gut health, but the scientific evidence is weak. DNA tests can identify certain genetic variants (e.g., lactose intolerance, FADS1) that have a small impact on digestive function. However, gut health is predominantly shaped by diet, microbiome composition, stress, medications, and lifestyle – not genetics. The included 28-day plan and recipe book are likely generic rather than truly personalized. No robust studies demonstrate that such a test leads to meaningful improvements in gut health outcomes. The evidence level is best described as 'marketing'. Consumers should remain critical: without medical supervision or specific symptoms, the utility is questionable. A focus on a balanced, fiber-rich diet and possibly a stool microbiome analysis would be more evidence-based.
