What to watch with Ferritin Eisenmangel and Langlebigkeit?

Ferritin is the main iron storage protein. Low ferritin indicates iron deficiency, which can cause fatigue, poor concentration, and impaired immune function – factors that may indirectly affect healthy longevity. However, the direct link between iron deficiency and longevity is complex: iron is essential for oxygen transport and cellular energy, but excess iron promotes oxidative stress, a driver of aging. Evidence suggests both deficiency and overload can shorten lifespan. Iron deficiency should be medically investigated (e.g., blood loss, inflammation, malabsorption). Supplementation should only follow measurement of ferritin, transferrin, and CRP, as overload is harmful. Maintaining a balanced iron status – neither deficient nor excessive – appears beneficial for longevity. The evidence is mostly mechanistic and epidemiological; long-term randomized trials are lacking.
