Is Nährstoffcheck useful for Wechseljahre?

A nutrient check (e.g., blood analysis of vitamins and minerals) can be useful during menopause because hormonal shifts alter requirements for nutrients like vitamin D, calcium, magnesium, B vitamins, and iron. However, a DNA-based nutrient check (e.g., from saliva) has limited predictive value: genetic variants (e.g., in VDR, MTHFR) show small effects on metabolism but do not directly measure current nutrient levels. The evidence is mixed: some biomarkers (e.g., vitamin D, ferritin) are clinically validated, while most genetic associations lack robust replication. A nutrient check can provide orientation but should be interpreted alongside clinical symptoms and lab results. It is not a substitute for medical advice.
