What can the Nährstoffcheck tell you — and what not?

The MyBody-X Nährstoffcheck measures key micronutrients such as vitamin D, ferritin (iron), vitamin B12, and folate in the blood. It provides a snapshot of your current status and can help identify common deficiencies. However, it has clear limitations: it does not reveal the underlying cause of a deficiency (e.g., malabsorption, chronic inflammation, or medication effects). Ferritin can be falsely elevated during inflammation, masking iron deficiency. Genetic variants like MTHFR are not assessed in this blood test – separate DNA tests exist but only indicate predispositions, not diagnoses. The Nährstoffcheck is not a substitute for medical evaluation; abnormal results should be discussed with a doctor, especially before supplementing. Additionally, not all relevant markers (e.g., selenium, zinc, copper) are included. The results are a guide, not a comprehensive health assessment. Evidence grade: practice (based on experience and lab standards).
