Because of this health risk with high iron intake, the Institute of Medicine has set a Tolerable Upper Intake Level, or UL, for iron.

The average daily iron intake from foods and supplements is 13.7â15.1 mg/day in children aged 2â11 years, 16.3 mg/day in children and teens aged 12â19 years, and 19.3â20.5 mg/day in men and 17.0â18.9 mg/day in women older than 19.
