Evidence check: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch in the context of fatigue

The INFINITY DNA-Test including a 28-day plan and recipe book is marketed as a personalized solution for fatigue. However, the scientific evidence for such combo products is weak. DNA tests can identify certain genetic variants (e.g., in MTHFR, COMT, FOXO3), but their effect on fatigue is typically very small and not clinically actionable. Fatigue has many causes: iron deficiency, thyroid dysfunction, poor sleep, stress, infections, or psychological factors. A standalone DNA test cannot assess these. The included 28-day plan and recipe book are likely generic dietary guidelines, not truly personalized to your genetics. No randomized controlled trials support this specific test for improving fatigue. Evidence is marketing-based. Caution: Do not rely on this test as a sole diagnostic or treatment tool. If you experience persistent fatigue, consult a physician to rule out underlying medical conditions.
