Ferritin is a protein complex that stores iron. It is composed of apoferritin and iron core Fe3+. Serum ferritin can reflect the total amount of iron stored in the body and the nutritional status of iron. If ferritin is low, it means that the iron content is also low, and iron deficiency anemia may occur.

While following the doctor’s recommendations for drug treatment, you can also supplement foods containing heme iron, such as red meat (lean meat, beef, pig blood, duck blood, pig liver, etc.), fish and Poultry, black rice, purple rice cereals, etc. can increase the body's iron intake.
