Can Eisen-Ferritin Selbsttest help with longevity?

An iron-ferritin self-test measures your ferritin level, a marker of iron storage. Optimal iron status is crucial for many bodily functions, and both deficiency and overload have been linked to accelerated aging (e.g., oxidative stress from iron excess). However, a single self-test without medical guidance is unlikely to directly improve longevity. The evidence for a causal link between ferritin self-testing and extended lifespan is weak and primarily mechanistic. Moreover, ferritin can be elevated by inflammation or infection, leading to misinterpretation. While such a test can serve as a screening tool, it should be interpreted by a healthcare professional. Without clinical context, there is a risk of unnecessary supplementation or overlooking underlying conditions. In summary, the test provides a snapshot of iron status but is not a proven longevity intervention. Evidence: mechanistic/unclear.
