Evidence check: Ferritin Eisenmangel in the context of Wechseljahre

Ferritin is a key marker for iron stores, but interpretation during menopause is complex. Estrogen decline can promote low-grade inflammation, raising ferritin as an acute-phase reactant – even when iron is truly deficient. Meanwhile, iron needs decrease after menstruation stops. A low ferritin (<30 µg/L) reliably indicates depleted stores, but a normal ferritin does not rule out functional iron deficiency. Evidence is mixed: clinical guidelines recommend a full iron panel (ferritin, transferrin saturation, CRP). Caveat: Do not rely on single biomarkers or direct-to-consumer genetic tests for iron status; consult a physician.
