Mango contains a moderate amount of potassium. One cup of raw mango pieces provides about 277 mg of potassium, which is roughly 8% of the daily adequate intake for adult men (3,400 mg) and about 11% for adult women (2,600 mg). That puts mango in the middle of the pack among fresh fruits, not particularly high or low.
How Mango Compares to Other Fruits
To put mango’s potassium content in perspective, here’s how one cup of common fruits stacks up, using USDA data:
- Passion fruit: 821 mg
- Kiwifruit (green): 562 mg
- Oranges: 333 mg
- Lychees: 325 mg
- Tangerines: 324 mg
- Mango: 277 mg
- Papaya: 264 mg
Mango delivers less potassium per cup than oranges, kiwi, and tangerines. It lands close to papaya. Dried fruits are a different story entirely: a cup of dried apricots packs over 1,000 mg of potassium because removing water concentrates all the minerals into a smaller, denser serving.
Bananas are the fruit most people associate with potassium, and a medium banana typically provides around 420 mg. So cup for cup, mango delivers noticeably less potassium than a banana.
What Counts as “High Potassium”
Whether mango qualifies as “high potassium” depends on the context. For the average healthy person eating a balanced diet, mango is a moderate source. It contributes some potassium but isn’t an especially concentrated one. You’d need to eat several cups in a sitting to get a large dose.
For people managing kidney disease, though, the threshold is different. The National Kidney Foundation classifies any food with more than 200 mg of potassium per serving as “higher in potassium,” and a medium mango crosses that line. If you’re on a potassium-restricted diet for kidney health, mango falls into the category your care team would want you to track carefully. Portion size matters a lot here: half a mango rather than a whole one can keep you in a more comfortable range.
Serving Size Changes the Picture
The way you eat mango affects how much potassium you actually take in. A single cup of diced mango (about 165 grams) gives you roughly 277 mg, but a whole medium mango is larger than one cup’s worth and can deliver over 300 mg. Mango is easy to eat in large quantities, especially blended into smoothies or sliced as a snack, so the potassium can add up without you realizing it.
Dried mango concentrates the fruit’s nutrients into a much smaller volume, similar to what happens with dried apricots and peaches. A handful of dried mango chips contains more potassium than the same weight of fresh mango. If you’re watching your intake, fresh mango in controlled portions is easier to manage than dried.
Mango’s Broader Nutritional Value
Potassium is only one piece of the picture. Mango is exceptionally rich in vitamin C and vitamin A (from beta-carotene), and it provides dietary fiber, folate, and smaller amounts of magnesium and copper. If you’re eating mango for general health, it’s a nutritious choice regardless of its moderate potassium content.
For people actively trying to increase their potassium intake to support blood pressure or heart health, mango contributes but isn’t the most efficient option. Reaching for kiwi, passion fruit, or even a banana alongside your mango will get you closer to daily targets faster. On the other hand, if you’re trying to limit potassium, mango in small portions is a reasonable fruit to include, especially compared to higher-potassium options like passion fruit or dried fruits.
