The explanation â the true one (if ever found) â does matter. It may matter to future whales, potentially, especially if we learn that 52 Hertz (âAliceâ, as in Cooper) got the way s/he did because of us, because of something we humans were/are doing.
Because of this health risk with high iron intake, the Institute of Medicine has set a Tolerable Upper Intake Level, or UL, for iron. This is the highest amount of iron that can be taken daily with a low risk for developing overload. For males and females over 14 years old, the UL for iron is 45 milligrams per day.
The recommended dietary allowance for iron is dependent on your age and your gender. For men that are 19-50 years old, 8 milligrams per day is the requirement. For women that are 19-50 years old, the requirement is 18 milligrams per day due to the loss of blood, as well as iron, through monthly menses.
