Can INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch help with fatigue?

The INFINITY DNA-Test with a 28-day plan and recipe book is marketed to help with fatigue, but the scientific evidence is weak. DNA tests for fatigue typically analyze variants in genes like COMT, MTHFR, or BDNF, which may influence energy metabolism or stress resilience. However, effect sizes are small, non-deterministic, and overshadowed by lifestyle, sleep, diet, and medical conditions. No randomized controlled trials show that such a test plus plan significantly reduces fatigue. The 28-day plan and recipe book are likely generic and not backed by personalized evidence. Caution: fatigue has many causes (iron deficiency, thyroid issues, sleep apnea, depression). A DNA test does not replace a medical workup. Evidence grade: marketing/unclear. Sources: none specific in context.
