Ferritin is your body's iron storage protein. Think of it as your iron savings account. It is the most reliable single marker of iron stores and often drops before any other sign of deficiency appears. The tricky part: ferritin is also an inflammation marker. It rises when the body is fighting infection or dealing with chronic inflammation, which can mask true iron deficiency.
