For the full breakdown, see our best Drinks with Potassium guide.
When you need to boost your potassium intake, the glass in your hand matters more than most people realize. While bananas get all the attention, a single cup of prune juice delivers more potassium than two medium bananas, and it’s far easier to drink than to chew.
The drinks below are ranked by milligrams per standard one-cup serving, so you can compare them directly against your daily target of 2,600 to 3,400 mg.
The Highest-Potassium Drinks, Ranked by Serving
One cup means eight fluid ounces, and these figures reflect unsweetened, unfortified versions of each drink unless noted otherwise. Here’s how the leading beverages stack up:
| Drink (1 Cup / 8 oz) | Potassium per Serving | Best For |
|---|---|---|
| Prune juice | 707 mg | The single highest single-serving option |
| Carrot juice | 689 mg | Vegetable lovers who want beta-carotene too |
| Pomegranate juice | 533 mg | Antioxidants plus a strong potassium hit |
| Tomato juice | 527 mg | Savory flavor and a low-sugar option |
| Fresh orange juice | 496 mg | A familiar breakfast staple |
Milk, coffee, tea, and other nonalcoholic beverages also rank among the top potassium sources in the typical U.S. adult diet, per the same NIH data. That observation describes what people actually drink, not a recommendation to increase intake. For anyone who needs more potassium, the five juices above deliver the most per cup, but the best choice depends on your taste and your daily routine.
Why Serving Size and Product Type Change the Numbers
The potassium in your glass shifts with what you buy and how much you pour. Fortified drinks can carry significantly more potassium than their unfortified counterparts, and some orange juice products list 443 mg per cup rather than the 496 mg shown in the table. That variation comes down to the specific product, so the label on the carton is the most reliable number for what you’re actually drinking.
Serving size matters just as much. The flip side is also true: a splash of juice in a smoothie adds only a fraction of the table’s values, so portion control cuts both ways.
The NIH source material notes that drink potassium content varies by product type, fortification, and serving size, which is why the exact figures above match specific products. If you’re tracking potassium for a medical reason, use the values from the package and verify portions carefully. If you’re just trying to add more of this mineral to your day, the ranking holds up: prune juice and carrot juice lead the field, with pomegranate, tomato, and orange close behind.
How to Pick the Right High-Potassium Drink for You
The best drink is the one you’ll actually finish, but a few practical filters narrow the choice. Sugar content separates the options more than potassium does: tomato juice and carrot juice carry the least sugar per serving, while prune and pomegranate juices are notably sweeter. Calories follow the same pattern, so anyone watching either number will gravitate toward the vegetable juices.
Taste is the other deciding factor. Prune juice has a bold, date-like flavor that some people love and others find too heavy. Carrot juice is milder and pairs well with ginger or apple. Pomegranate juice is tart and concentrated, often mixed with water or sparkling water. Tomato juice works as a savory option that fits a bloody mary or a standalone glass over ice.
For anyone ready to add a potassium-rich drink to their regular rotation, our roundup of the best drinks with potassium covers the top store-bought options, their taste profiles, and which ones deliver the most per bottle. The data above gives you the numbers; that guide helps you find the bottle.
FAQs
Is coconut water a good source of potassium?
It’s a lighter, lower-calorie option than most fruit juices, though the exact count varies by brand and coconut maturity. Check the label for the precise value.
How much potassium do I need per day?
Healthy adults should aim for 2,600 to 3,400 mg of potassium daily, with the exact target depending on age, sex, and health status. One cup of prune juice covers roughly a quarter of that goal. Anyone with kidney disease or on blood pressure medications should consult a doctor before increasing intake.
What drink has more potassium than a banana?
Pomegranate, tomato, and orange juice also beat the banana per cup. That makes juice a more efficient way to hit a potassium target than eating the fruit.
