Can MY FOODBOOK help with Müdigkeit?

MY FOODBOOK is a MyBody-X product that provides personalized nutrition recommendations based on DNA testing. However, there is no direct scientific evidence that MY FOODBOOK specifically helps with fatigue (Müdigkeit). Fatigue has many potential causes: iron deficiency, sleep disorders, stress, thyroid issues, or genetic factors such as variants in TNF or FUT2 that may subtly influence inflammation or gut health. A DNA test like MY FOODBOOK could theoretically flag such genetic predispositions, but effect sizes are small and not deterministic. Moreover, MY FOODBOOK does not measure current biomarkers like ferritin (iron stores), which are more directly relevant to fatigue. Without dedicated studies linking MY FOODBOOK to fatigue outcomes, the evidence remains weak. Individuals suffering from persistent fatigue should prioritize medical evaluation (e.g., blood count, ferritin, thyroid function) rather than relying solely on genetic tests. MY FOODBOOK may serve as a lifestyle awareness tool but is not a substitute for clinical diagnosis or treatment.
