Ferritin

Ferritin provides an early signal of whether your iron reserves are too low or too high before symptoms appear. Low ferritin usually points to iron deficiency, which can progress to anemia and cause fatigue, weakness, and reduced exercise tolerance. High ferritin can indicate inflammation, liver problems, or iron overload, which may damage organs over time. Diet (iron-rich foods, vitamin C intake), blood loss (menstruation, GI bleeding), and supplements strongly influence ferritin.

Monitoring helps detect imbalances early so you can adjust nutrition, treat underlying causes, and prevent complications.
