Potassium is a nutrient that’s helps regulate fluid balance, muscle contractions, and nerve signals. Most people can meet their needs through food, but it’s worth knowing what it does and where to find it.
How much do you need?
General guidance suggests around 2,600mg for adult women and 3,400mg for adult men per day, though individual needs can vary based on age, sex, and health status. These figures are population-level guidelines, not a personal prescription.
Food sources
- Bananas and oranges
- Potatoes (with skin)
- Beans and lentils
- Leafy greens and tomatoes
Worth knowing
Potassium needs can be affected by certain medications and kidney conditions, so people managing those should talk to a healthcare provider about intake.
If you’re concerned about whether you’re getting enough of this nutrient, a blood test and conversation with a healthcare provider is the most reliable way to know — general food-based guidance like this is educational, not a personal diagnosis.
