Why does a body not store iron?

The body does store iron, but it does so in a limited and regulated manner to prevent toxicity. Iron is primarily stored in the liver, spleen, and bone marrow as ferritin and hemosiderin. Excess iron can lead to oxidative damage and organ dysfunction, so the body tightly controls iron absorption and storage. Additionally, the body lacks a mechanism for excreting excess iron, making regulation essential for health.
