Ferritin is an iron-storage protein that exists in large quantities in bacteria, plants, and the blood of many mammals, including humans. (1−3) This intracellular protein naturally stores iron and releases it in a controlled fashion. Ferritin plays a key role in preventing diseases and in the detoxification of metals in living organisms.
