No, one banana does not provide enough potassium for your entire daily need, but it's a great source, offering about 9-12% of the recommended daily value (DV) for adults (around 320-422 mg). While bananas are famous for potassium, you need several servings of potassium-rich foods like spinach, sweet potatoes, beans, and avocados, in addition to bananas, to reach the recommended daily intake of roughly 4,700 mg for most adults.
Bananas are not dangerous - and in fact they are, and always have been, very good for you. Adults should consume about 3500mg of potassium per day. The average banana, weighing 125g, contains 450mg of potassium, meaning a healthy person can consume at least seven-and-half bananas before reaching the recommended level.
Key Points. Eating up to 2 servings of bananas caused marginal increases in plasma potassium concentration. The small increases in plasma potassium concentration occurred 30 to 60 minutes postingestion of bananas. Eating bananas is unlikely to be an effective treatment for exercise-associated muscle cramping.
Yes, potassium can cause nausea, either from high levels in the blood (hyperkalemia), which affects nerves and muscles, or as a side effect from potassium supplements, causing general stomach upset, diarrhea, and vomiting, especially with sudden or severe increases. While mild high potassium often has no symptoms, severe or sudden cases need immediate medical attention, as does persistent nausea from supplements, notes the National Kidney Foundation and WebMD.

The best sources of potassium
A small drop in the blood potassium level often does not cause symptoms or causes mild to moderate symptoms, which may include:
Currently, no home fingerprick collection potassium tests are available. Although potassium is one of the biomarkers offered by the Kitby Vitall kidney function home test,34 it requires a clinic visit (at additional cost) to obtain the blood.
It can also irritate your esophagus, which can cause heartburn pain. Taking potassium citrate with a meal or snack, staying hydrated, and remaining upright for at least 30 minutes after taking your dose can help you avoid or improve these gastrointestinal (GI) symptoms.
Potassium chloride is usually best for treating low potassium levels, while potassium citrate is often best for kidney stones. Learn more about choosing the best supplement for you. Can low potassium cause dizziness? Understanding what low potassium can feel like is important if you're at risk for low levels.
Eating a ripe banana helps: Eat 2 – 3 bananas a day to regulate bowel movements and relieve constipation.
What foods provide potassium?
You should consume bananas in the morning time with other breakfast items and avoid eating bananas on an empty stomach at all times. There is no scientific evidence that concludes that it is harmful to eat bananas at the night time.
Oral potassium tablets typically contain around 12 mmol of potassium and should be administered with food to reduce their alimentary side effects, which include nausea and vomiting. This is equivalent to one medium banana. Bananas are a well accepted source of potassium; 1 g of banana contains 1 mmol of potassium.
Broccoli is a medium potassium food, low in sodium and phosphorus, and suitable for all the following kidney conditions and treatments: Chronic Kidney Disease (CKD) Transplant.
What blocks potassium absorption? Aside from diuretics and laxatives, some other medicines, such as steroids and some antacids, may either block your ability to absorb potassium or cause you to lose more when you pee and poop. Too much sodium in your diet may cause you to lose more potassium when you pee.

If you have low levels of potassium, you may experience an increase in your anxiety symptoms. Anxiety is an abnormal feeling of worry, fear, apprehension or nervousness.
Possible potassium citrate interactions include spironolactone (Aldactone), lisinopril (Zestril), and losartan (Cozaar). It can also interact with potassium supplements, ibuprofen (Advil, Motrin), and celecoxib (Celebrex).
High potassium drinks include fruit and vegetable juices (like prune, carrot, orange, tomato), coconut water, milk, and some electrolyte drinks, offering significant amounts of this mineral crucial for hydration and nerve function, with options ranging from sweet (fruit juices) to savory (tomato juice) and refreshing (coconut water).
Your healthcare provider will check your potassium level through a blood test. The normal potassium level for an adult ranges from 3.5 to 5.2 mEq/L (3.5 to 5.2 mmol/L). Potassium levels between 3 and 3.5 mEq/L (3 to 3.5 mmol/L) are considered mild hypokalemia.
Low potassium levels can affect the muscles in the intestines, which can slow the passage of food and waste. This effect on the intestines can cause constipation and bloating.
5 Signs of an Electrolyte Imbalance
Low potassium has many causes. The most common cause is potassium loss in urine due to prescription medicines that increase urination. These types of medicines, also known as water pills or diuretics, typically are prescribed to treat high blood pressure or heart disease.
