The European Food Safety Authority (EFSA) refers to the collective set of information as Dietary Reference Values, with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR. AI and UL defined the same as in United States. For women and men ages 15 and older the PRIs are set at 650 and 750 μg/day, respectively. PRI for pregnancy is 700 μg/day, for lactation 1300/day. For children ages 1–14 years the PRIs increase with age from 250 to 600 μg/day. These PRIs are similar to the U.S. RDAs. The European Food Safety Authority reviewed the same safety question as the United States and set a UL at 3000 μg/day.
