Daily Potassium Intake Calculator
NIH-recommended daily potassium intake by sex.
A general population guideline (NIH adequate intake), not medical advice — people with kidney disease or on certain blood pressure or heart medications should get a personalized potassium target from a doctor, since too much can be dangerous with those conditions.

Why potassium gets less attention than sodium
Potassium helps counterbalance sodium's effect on blood pressure and supports normal muscle and nerve function, but most public health messaging focuses on cutting sodium rather than increasing potassium — even though raising potassium intake is at least as effective for blood pressure. Bananas are the classic example, but potatoes, beans, and leafy greens all deliver more potassium per serving. For the sodium side of that balance, see our sodium intake calculator.
Frequently asked questions
Why does this recommendation only vary by sex, not age?
Unlike several other nutrients, NIH adequate intake guidance for potassium is set primarily by sex for most of adulthood, reflecting typical differences in body size, rather than shifting significantly across adult age brackets.
