Why we cite it
An authoritative, non-commercial safety reference for potassium intake from supplements and salt substitutes. Establishes that although potassium from food is generally safe for healthy people, very high amounts from supplements or potassium-containing salt substitutes can exceed the kidneys’ excretory capacity and cause acute hyperkalemia — even in otherwise healthy individuals — and that certain conditions and medications sharply raise this risk. Directly supports the companion’s caution to keep supplemental potassium moderate and to involve a clinician when medical conditions are present.
