Iron is stored by the liver, mainly in the form of ferritin and hemosiderin within liver cells (hepatocytes) and resident macrophages (Kupffer cells). Ferritin serves as the readily mobilizable iron store, while hemosiderin acts as a reserve when stores are high. The liver also helps regulate iron balance through hepcidin, which controls iron absorption and release from stores.

Calcium, sodium, and potassium are not stored in the liver as primary reservoirs: calcium is mainly stored in bone, and sodium and potassium are tightly regulated across body fluids and intracellular compartments rather than stored in the liver.
