Can Ferritin help with Langlebigkeit?

Whether ferritin directly aids longevity requires nuanced interpretation. Ferritin is the primary iron storage protein. Optimal ferritin levels are crucial for many physiological processes, but direct causal evidence for lifespan extension is lacking from strong human trials. Low ferritin (iron deficiency) can cause anemia, fatigue, and impaired immunity – factors reducing healthspan. High ferritin may indicate iron overload (e.g., hemochromatosis), promoting oxidative stress and linked to increased risk of cardiovascular disease, diabetes, and neurodegeneration – all impacting longevity. However, ferritin alone is insufficient as a longevity biomarker. Evidence comes from observational studies and mechanistic pathways, not from RCTs showing lifespan extension through ferritin modulation. Consumer tests like MyBody-X measure blood ferritin, useful for prevention but not a longevity guarantee. Interpretation must consider inflammation (ferritin is an acute-phase reactant). Conclusion: Ferritin monitoring can indirectly support longevity by detecting iron imbalances, but it is not a standalone longevity tool. Evidence: mechanistic/observational.
