Bananas get all the credit, but dozens of fruits pack more potassium per serving. A medium banana delivers about 403 mg of potassium, which is only 12% of the 3,400 mg daily target for adult men or 15% of the 2,600 mg target for adult women. Dried fruits, tropical fruits, and even common juices can deliver two to five times that amount.
Dried Fruits Top the List
Removing water from fruit concentrates everything, including potassium. Dried apricots are the standout: a cup of dehydrated, low-moisture apricots contains roughly 2,202 mg of potassium, more than half a day’s worth for most adults. Even a modest portion of 10 dried apricot halves provides 407 mg, about the same as a whole banana.
Dried peaches follow at around 1,341 mg per cup (stewed), and dried currants come in at 1,119 mg per cup. Prunes deliver 398 mg in just half a cup, and a quarter cup of raisins adds 272 mg. The tradeoff is that dried fruit is also calorie-dense and high in natural sugar, so portion size matters. A small handful mixed into oatmeal or yogurt is a practical way to boost your intake without overdoing it.
For perspective, a single fresh apricot contains only 91 mg of potassium. The same fruit dried has roughly four times the potassium per piece, simply because the water is gone and the minerals are packed into a smaller volume.
Fresh Fruits With the Most Potassium
Among fresh options you can find at most grocery stores, these deliver the most potassium per serving:
- Avocado: 583 mg per fruit. Technically a fruit, and one of the richest whole-food potassium sources available.
- Kiwi: 562 mg per cup of sliced green kiwi.
- Banana: 403 mg per medium fruit. A solid source, just not the best one.
- Guava: 344 mg per fruit.
Passion fruit is another strong option at 821 mg per cup of pulp, though you’d need quite a few fruits to fill a cup. Breadfruit, common in Caribbean and Pacific Island cuisines, delivers 1,078 mg per cup of raw flesh.
Fruit Juices Can Deliver Even More
Juice concentrates pack potassium into an easy-to-consume form. A cup of reconstituted frozen orange juice concentrate contains about 1,648 mg of potassium. Frozen grapefruit juice concentrate provides around 1,002 mg per six-ounce can before dilution. Even diluted to drinking strength, these juices remain among the highest potassium sources in the fruit category.
The downside is the same as with dried fruit: juice delivers sugar without the fiber that slows its absorption. If you’re choosing juice primarily for potassium, a small glass alongside whole fruits and vegetables gives you the mineral without a blood sugar spike.
How Potassium Works in Your Body
Potassium’s most important job is regulating blood pressure. It relaxes blood vessel walls by activating pumps in muscle cells that shift the balance of electrical charge across the cell membrane. This causes the vessels to widen, which lowers pressure. Potassium also helps your kidneys flush out excess sodium through urine, which is why people with salt-sensitive blood pressure often see the biggest benefit from increasing their potassium intake.
Beyond blood pressure, potassium reduces the amount of stress hormones available at nerve endings in your blood vessels. Less stimulation means less constriction, which further supports healthy blood flow. These effects work together, which is why potassium from food has a measurable impact on cardiovascular health over time.
How Much You Actually Need
The recommended daily intake varies by age and sex. Adult men 19 and older need 3,400 mg per day. Adult women in the same age range need 2,600 mg. Pregnant women need 2,900 mg, and breastfeeding women need 2,800 mg. Most Americans fall short of these targets, which were set by the National Academies of Sciences based on the best available intake data.
Fruits alone won’t get you there. A cup of dried apricots at 2,202 mg gets you impressively close, but realistically, potassium intake should come from a mix of fruits, vegetables, beans, dairy, and meat throughout the day. Think of high-potassium fruits as a reliable contributor, not the sole source.
Who Should Be Careful
Healthy kidneys handle potassium easily, filtering out whatever you don’t need. But kidneys affected by chronic kidney disease lose that ability. Potassium can build up in the blood, and levels that climb too high cause dangerous heart rhythm problems. People with kidney disease typically work with a dietitian to find a safe range, and they’re often advised to choose lower-potassium fruits like apples, grapes, and cranberries instead of oranges or bananas.
Certain blood pressure medications also change the equation. Some drugs, particularly the type that reduce the hormone aldosterone, cause the body to retain potassium instead of excreting it. If you take medication for blood pressure or heart failure, your doctor may already be monitoring your potassium levels. Loading up on high-potassium fruits without knowing your blood work could push levels into an unsafe range.
Practical Ways to Add More
If you’re trying to increase your potassium intake, variety beats volume. A sliced kiwi at breakfast (562 mg), half an avocado at lunch (roughly 290 mg), and a small handful of dried apricots as a snack (400 mg) adds up to about 1,250 mg from fruit alone, without eating anything unusual or unpleasant. Add in the potassium from vegetables, beans, potatoes, and dairy over the course of the day, and hitting your target becomes realistic.
Whole fruits generally deliver potassium alongside fiber, vitamin C, and other nutrients that work together in ways a supplement can’t replicate. The body absorbs potassium efficiently from food, and the other compounds present in fruit (like citrate) support kidney health and bone density in their own right. When you have the choice between a potassium pill and a piece of fruit, the fruit is doing more for you.
