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.
Recommended Intake. Men and women over 50 need at least 8 milligrams of iron per day, while women 50 and under need at least 18 milligrams of iron per day. You shouldn't consume more than 45 milligrams of iron per day from supplements or food, as this could cause toxicity symptoms.
