What role does Fitness Vitality DNA play in Müdigkeit?

The role of the Fitness Vitality DNA test in fatigue is scientifically weak. The test may analyze genetic variants related to energy metabolism, mitochondrial function, or nutrient processing – e.g., iron, vitamin B12, or thyroid hormones. However, fatigue is a multifactorial symptom far more often caused by lifestyle (sleep deprivation, stress, diet), psychological factors, or clinical conditions (anemia, hypothyroidism, sleep apnea). Genetic effects are typically small and insufficient to explain or treat individual fatigue. MyBody-X markets such tests with general health claims, lacking robust clinical validation. A DNA test can at best suggest rare predispositions but does not replace medical workup. Evidence grade: marketing/mixed. Caveat: No diagnosis or treatment recommendation from genetics alone. For persistent fatigue, consult a physician for blood work, thyroid panel, and sleep assessment.
