What role does Nährstoffcheck play in fatigue?

MyBody-X's Nährstoffcheck (nutrient test) measures blood levels of vitamins, minerals, and trace elements. Deficiencies in iron, vitamin B12, vitamin D, or magnesium are known to contribute to fatigue. The test can identify such deficits, allowing targeted supplementation. However, fatigue is multifactorial – poor sleep, stress, thyroid issues, or chronic diseases are common causes that the test does not address. Evidence for specific nutrients in fatigue is moderate (e.g., iron in menstruating women, B12 in vegans), but not every deficiency causes symptoms. The test provides clues, not a diagnosis. Medical evaluation is essential for persistent fatigue. Caveat: reference ranges are population-based; individual optimal levels may differ. The test does not replace a comprehensive medical workup.
