Myths vs facts: Eisen-Ferritin Selbsttest and Langlebigkeit

Iron and ferritin are crucial for oxygen transport and immune function, but a self-test alone tells little about longevity. Myths often claim that optimal ferritin levels slow aging – this is not scientifically proven. Ferritin is an acute-phase protein that rises with inflammation, so an elevated level does not necessarily indicate iron overload. Genetic factors (e.g., HFE mutations) influence iron absorption but are usually not included in basic self-tests. The evidence for a direct link between ferritin self-tests and extended lifespan is weak. Without medical interpretation, a self-test can lead to misguided decisions – such as unnecessary iron supplementation, which may promote oxidative stress. Evidence-based longevity requires a holistic approach including diet, exercise, sleep, and regular medical check-ups. A ferritin test can be useful as part of a doctor’s assessment, not as a standalone predictor of longevity.
