Question

Quizplus · Accepted Answer

The pharmacist should use Tolerable Upper Intake Levels (ULs) to provide the best recommendation for the highest amount of iron supplement to take daily. Exceeding the UL for iron can lead to toxic effects, such as gastrointestinal distress, organ damage, and interfering with the absorption of other nutrients. The other options (RDAs, AIs, EARs, and AIs and EARs) are not appropriate for determining the highest safe daily intake of a nutrient.
