How much iron can the body absorb per day?

Of about 15 mg per day of dietary iron, adults absorb only 1 mg, which is the approximate amount lost daily by cell destruction. In iron depletion, absorption increases, although the exact signaling mechanism is unknown; however, absorption rarely increases to more than 6 mg per day unless supplemental iron is added.

How can I get 18 mg iron a day?

Eating certain dark, leafy greens, meat, seafood, beans, nuts, and seeds can help a person to boost their iron intake.

What does too much iron in your blood mean?

Hemochromatosis is a genetic disorder that causes the body to store too much iron, resulting in high iron levels. This disorder occurs when the HFE gene is passed to a child by a parent. If the disease progresses without treatment, it can cause cirrhosis, liver cancer, diabetes and heart problems.
