welche blutwerte bei erschöpfung — what can you do yourself?

Exhaustion is multifactorial – lack of sleep, chronic stress, or nutrient deficiencies. Key blood markers include ferritin (iron stores), vitamin B12, vitamin D, TSH (thyroid), and a complete blood count (hemoglobin, RBCs). CRP (inflammation) and fasting glucose are also useful. What you can do yourself: prioritize a balanced diet rich in iron and B12 (meat, legumes, whole grains), aim for 7–9 hours of sleep, get regular outdoor exercise, and manage stress (e.g., meditation). Supplement only after testing – never blindly. Caveat: single values like vitamin D or B12 are often borderline; a physician should interpret the full picture. Consumer blood tests (e.g., MyBody-X) provide raw data, not a diagnosis. Evidence for these markers is human-strong (clinical standard). Without medical follow-up, self-optimization may miss underlying conditions or cause harm (e.g., iron overload).
