welche blutwerte bei müdigkeit und erschöpfung — what can you do yourself?

For fatigue and exhaustion, relevant blood markers include iron/ferritin, vitamin D, vitamin B12, folate, thyroid (TSH), and possibly inflammatory markers like CRP. Home blood tests can screen these, but they are not diagnostic. What you can do yourself: eat a balanced diet rich in iron and vitamins, prioritize sleep, reduce stress, exercise moderately, and consider supplementation only after consulting a doctor. Evidence is practice-based; self-tests have limitations. Caveat: reference ranges may not fit your individual needs; always discuss results with a healthcare professional.
