What should I know about Ferritin Ernährung?

Ferritin is a protein that stores iron and serves as a key biomarker for iron status. Diet directly affects ferritin levels: iron-rich foods like red meat, legumes, and leafy greens can raise ferritin, while vitamin C enhances absorption and phytates (e.g., from whole grains) inhibit it. However, ferritin is also an acute-phase reactant; inflammation, infection, or liver disease can elevate ferritin without true iron overload. Therefore, elevated ferritin should always be interpreted alongside CRP or other inflammatory markers. Low ferritin (<30 ng/mL) indicates iron deficiency, which can be addressed through diet or supplementation. The evidence for dietary effects on ferritin is strong (human-strong), but individual factors like genetics (e.g., HFE mutations) and gut health also matter. MyBody-X tests can analyze genetic variants affecting iron absorption, but clinical utility is limited. Caution: high-dose iron without medical supervision can be harmful.
