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 people ages 15 and older the AI is set at 3,500 mg/day. AIs for pregnancy is 3,500 mg/day, for lactation 4,000 mg/day. For children ages 1–14 years the AIs increase with age from 800 to 2,700 mg/day. These AIs are lower than the U.S. RDAs. The EFSA reviewed the same safety question and decided that there was insufficient data to establish a UL for potassium.
