How are Nährstoffcheck and fatigue related?

A Nährstoffcheck (e.g., MyBody‑X) measures certain vitamins, minerals, or biomarkers in the blood. Deficiencies in iron, vitamin D, B vitamins, or magnesium can contribute to fatigue. However, a single test is not diagnostic – many factors like sleep, stress, or thyroid function affect energy levels. The test is intended as an educational tool, not a medical diagnosis. For persistent fatigue, a doctor should investigate underlying causes. The evidence is based on practice and general nutritional medicine, not on product‑specific studies. Caveat: A normal result does not rule out clinical deficiency, and an abnormal value requires medical confirmation.
