The U.S. Institute of Medicine (IOM) sets Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs), or Adequate Intakes (AIs) for when there is not sufficient information to set EARs and RDAs. Collectively the EARs, RDAs, AIs and ULs are referred to as Dietary Reference Intakes. The current AI for potassium for women and men ages 14 and up is 4700 mg. AI for pregnancy equals 4700 mg/day. AI for lactation equals 5100 mg/day. For infants 0–6 months 400 mg, 6–12 months 700 mg, 1–13 years increasing from 3000 to 4500 mg/day. As for safety, the IOM also sets Tolerable upper intake levels (ULs) for vitamins and minerals, but for potassium the evidence was insufficient, so no UL established.
