What to watch with Eisen-Ferritin Selbsttest and Langlebigkeit?

An iron-ferritin self-test can provide clues about your iron status, but for longevity the interpretation is nuanced. Ferritin is an acute-phase protein; elevated levels may reflect inflammation rather than iron stores, and chronic inflammation is linked to aging. Low ferritin (<30 µg/L) indicates iron deficiency, which can cause fatigue and impair cognition. High ferritin (>200 µg/L men, >150 µg/L women) may suggest hemochromatosis or inflammation – both associated with oxidative stress and accelerated cellular aging. Caveats: consumer tests lack clinical validation for diagnosis; ferritin alone is insufficient. Evidence for direct longevity effects is weak; iron homeostasis is one piece of a larger puzzle. Monitor CRP, transferrin saturation, and liver enzymes. Do not supplement iron without medical guidance, as overload can damage organs. For longevity, focus on a balanced diet, inflammation control, and regular checkups rather than single biomarkers.
