How to read this ranking
This page compares Potassium (Potassium, K), in mg per 100 g of food.
Chemical forms and measurement methods remain separate. “Not reported” means a value is unavailable, not that the food contains zero. A food’s rank does not determine your individual needs or diagnose a deficiency.
This NIH fact sheet concerns this nutrient. Its recommended amounts describe daily intake for the stated population, not a 100 g food portion. Keep food and supplement exposure separate as the source specifies.

Potassium: Fact Sheet for Consumers
Original text published by NIH, including intake tables by age and sex, cautions, and the population context the source states. Bitameans has not performed an independent medical review or adapted these recommendations to your personal circumstances.
What is potassium and what does it do?
Potassium is a mineral found in many foods. Your body needs potassium for almost everything it does, including proper kidney and heart function, muscle contraction, and nerve transmission.
How much potassium do I need?
The amount of potassium you need each day depends on your age and sex. Average daily recommended amounts are listed below in milligrams (mg).
| Life Stage | Recommended Amount |
|---|---|
| Birth to 6 months | 400 mg |
| Infants 7–12 months |
