Dose and safetyThe dose that worked and the upper limit
The studies of heme iron taken by mouth that showed an improvement gave 18 mg a day.
The upper limit for adults is 45 mg of iron a day, counted as the iron itself, not the weight of the compound; above it, members see a note and are told they can take less.
