About this calculator
Recommended daily potassium intake is set as an Adequate Intake (AI) value by nutrition authorities such as the US National Academy of Medicine, which updated its guidance in 2019 to roughly 3,400 mg/day for adult men and 2,600 mg/day for adult women — lower than the long-cited older 4,700 mg figure — with AI values varying further by age group and during pregnancy or lactation. Potassium is an essential electrolyte involved in fluid balance, nerve signal transmission, and muscle contraction, including the heartbeat.
Dietitians and physicians reference potassium AI targets when counseling on blood pressure management, since adequate potassium intake is associated with lower blood pressure and reduced stroke risk, and when advising patients on kidney disease or certain blood pressure medications, where potassium intake may need to be more carefully monitored rather than simply maximized.
This calculator takes your age and sex and returns your recommended daily potassium target based on current Adequate Intake guidelines.
