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.

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 |
