Sapote tops the list, delivering roughly 794 mg of potassium per cup. That’s nearly twice what you’d get from a medium banana, the fruit most people associate with potassium. Several other fruits come surprisingly close, and a few everyday options outperform bananas by a wide margin.
The Highest-Potassium Fruits, Ranked
Based on standard serving sizes from the Dietary Guidelines for Americans, here are the fruits that pack the most potassium per serving:
- Sapote or sapodilla: 794 mg per cup
- Jackfruit: 739 mg per cup
- Guava: 688 mg per cup
- Soursop: 626 mg per cup
- Kiwifruit: 562 mg per cup
- Durian: 530 mg per half cup
- Cantaloupe: 473 mg per cup
- Cherimoya: 459 mg per cup
- Banana: 451 mg per medium fruit
- Grapefruit: 415 mg per whole fruit
- Apricots: 401 mg per cup
- Honeydew melon: 388 mg per cup
Durian deserves special attention. At 530 mg per half cup, it’s the most potassium-dense fruit on the list relative to portion size. If you ate a full cup, you’d be well over 1,000 mg. Fresh jackfruit is similarly concentrated at 370 mg per half cup, though canned jackfruit drops dramatically to just 85 mg for the same amount, likely because potassium leaches into the canning liquid.
Where Bananas Actually Rank
Bananas have a reputation as the go-to potassium fruit, but they land in ninth place. A medium banana gives you 451 mg, which is solid but unremarkable next to a cup of kiwifruit (562 mg) or guava (688 mg). Even cantaloupe edges it out. Half an avocado, which is technically a fruit, provides about 364 mg, so it’s a decent source but not the powerhouse some claim.
The banana’s reputation likely comes from convenience and availability rather than nutritional superiority. If you’re specifically trying to increase your potassium intake, swapping in kiwi or cantaloupe gives you more per serving with less sugar.
Dried Fruit Concentrates Potassium
Drying fruit removes water and concentrates everything else, including potassium. Half a cup of dried apricots contains about 750 mg of potassium. The same amount of fresh apricots has roughly 200 mg. That’s nearly a fourfold difference. Dried peaches follow a similar pattern, with a quarter cup delivering 399 mg. Prunes come in at 319 mg per quarter cup, and raisins at 307 mg.
The trade-off is that dried fruit is also calorie-dense and high in natural sugars, so a quarter cup goes a long way. But if you’re looking for a portable, shelf-stable option to boost potassium, a small handful of dried apricots is one of the most efficient choices.
Juice Concentrates Potassium Too
Juicing strips out fiber but keeps the minerals. One orange contains about 240 mg of potassium, but 8 ounces of orange juice contains roughly 500 mg, because it takes several oranges to fill a glass. Prune juice leads all fruit juices at 707 mg per cup, followed by passion fruit juice at 687 mg and pomegranate juice at 533 mg.
This concentration effect is worth knowing if you have kidney concerns. People with chronic kidney disease are often advised to limit high-potassium foods, defined as anything with 200 mg or more per serving. A single glass of prune juice would deliver more than three times that threshold.
How Much Potassium You Actually Need
Adult men need about 3,400 mg of potassium per day. For adult women, the target is 2,600 mg. Most people fall short. A cup of sapote gets you about 23% of the way there for men and 31% for women, making it a meaningful contribution from a single food.
Your body absorbs potassium from food efficiently, taking in roughly 85% to 90% of what you eat. One study found absorption from supplements runs about 94%, which is only marginally better than absorption from whole foods like potatoes. So there’s no real advantage to popping a pill over eating potassium-rich fruit.
What Potassium Does in Your Body
Potassium works alongside sodium to maintain the electrical balance across every cell membrane. Your cells use a molecular pump that constantly pushes sodium out and pulls potassium in, which keeps cells at the right volume and maintains the electrical charge that muscles and nerves depend on. Without enough potassium, this balance shifts, and you can experience muscle cramps, fatigue, and irregular heartbeat.
This same pump system helps your kidneys regulate how much sodium and water you retain. Higher potassium intake helps your body excrete more sodium through urine, which is one reason potassium-rich diets are consistently linked to lower blood pressure. The relationship also runs through calcium regulation and pH balance, both of which depend on that sodium-potassium exchange working properly.
Practical Ways to Get More
If the top-ranking fruits like sapote, jackfruit, and durian aren’t at your grocery store, focus on what’s accessible. Kiwifruit, cantaloupe, and honeydew are widely available and outperform bananas. A cup of sliced kiwi with breakfast gives you over 560 mg. Adding a quarter cup of dried apricots as a snack pushes you past 900 mg from fruit alone.
Smoothies make it easy to combine multiple sources. Blend kiwi with a banana and half a cup of guava, and you’re looking at well over 1,000 mg in a single glass, without any supplements. For people who prefer juice, mixing orange juice with a splash of prune juice creates a high-potassium drink that doesn’t taste medicinal. Just keep in mind that whole fruit gives you the added benefit of fiber, which slows sugar absorption and supports gut health in ways juice can’t match.
