: NOTE: AI = Adequate Intake; CDRR = Chronic Disease Risk Reduction Intake; mg/d = milligrams per day; ND = not determined; UL = Tolerable Upper Intake Level.
a: Updated DRI value, as compared to the 2005 DRI Report.
b: Not determined owing to lack of a toxicological indicator specific to excessive potassium intake.
c: Not determined owing to insufficient strength of evidence for causality and intake–response.
