What do studies say about Ferritin Frauen?

Ferritin is the primary iron storage protein and a key biomarker for iron status. Studies consistently show that women of reproductive age have lower ferritin levels than men, mainly due to menstrual blood loss. A ferritin below 30 ng/mL indicates depleted iron stores, and below 15 ng/mL is diagnostic for iron deficiency anemia. During pregnancy and lactation, iron requirements increase substantially, making ferritin monitoring important. The provided context mentions the hemochromatosis variant rs1800562 (C282Y), which in heterozygous women can slightly increase iron absorption but rarely causes overload unless combined with excessive iron intake or menopause. However, most women with low ferritin do not have this variant. Evidence for ferritin as a marker is strong (human-strong), but caution is needed: ferritin is an acute-phase reactant and can be falsely elevated during inflammation, masking true deficiency. Consumer blood tests offer a snapshot; trends over time and clinical correlation are essential. For women with fatigue, hair loss, or poor concentration, a full iron panel (ferritin, serum iron, transferrin saturation, hemoglobin) is recommended. Always consult a healthcare provider before supplementing iron, as excess can be harmful.
