how much potassium a day
Most healthy adults should aim for about 3,500–4,700 mg of potassium per day from food, unless a doctor has told them to limit it.
Quick Scoop
- Typical target range for healthy adults: 3,500–4,700 mg/day from food.
- Common guideline:
- Adult men: around 3,400 mg/day.
* Adult women: around **2,600 mg/day**.
- Many public health bodies consider 3,500 mg/day a good minimum goal for adults.
- Most people eat less than this (often around 2,300–3,000 mg/day), so increasing potassium-rich foods is usually helpful.
When these numbers may change
You may need medical advice and possibly a lower limit if you have:
- Kidney disease or reduced kidney function (kidneys clear potassium).
- Certain heart conditions or are on medications like ACE inhibitors, ARBs, potassium-sparing diuretics, or high-dose potassium supplements.
You may benefit from the higher end of the range (closer to 4,700 mg/day) if you are:
- Eating a high-salt (high-sodium) diet and trying to improve blood pressure.
- Generally healthy and increasing fruits, vegetables, and legumes for heart and blood pressure benefits.
Simple example day (food-based)
A rough example that gets you near the target might include:
- 1 baked potato with skin: ~550 mg
- 1 banana: ~320 mg
- 1 cup cooked beans or lentils: ~500–700 mg
- 1 cup cooked spinach or chard: ~500–900 mg
- 1 avocado: ~480 mg
Combined with the rest of your meals, that can easily bring you into the 3,500–4,700 mg/day range from food alone.
If you have kidney, heart, or blood pressure issues or take regular prescription meds, check with your doctor or dietitian before changing potassium intake or adding supplements.
