What to watch with NutriCare | INFINITY DNA-Test and Müdigkeit?

The NutriCare | INFINITY DNA-Test is marketed as a comprehensive health assessment, but caution is warranted regarding fatigue. The evidence for many of the tested genes is weak or purely mechanistic. Fatigue is a multifactorial symptom that can be caused by sleep deprivation, stress, diet, exercise, or medical conditions (e.g., iron deficiency, thyroid issues). DNA tests may identify risk variants (e.g., MTHFR, COMT), but their effect on fatigue is typically small and not well-validated. The results often lack clinically actionable recommendations. Without medical workup and blood biomarkers (e.g., ferritin, vitamin D, B12), interpretation remains speculative. Many offered markers are not validated for diagnosing fatigue. Consumers should not rely on such tests as the sole basis for supplements or dietary changes. The evidence is mostly marketing-driven or based on weak associations. Consult a physician for persistent fatigue before acting on DNA results.
