Potassium-rich foods include white beans, lentils, potatoes and sweet potatoes with skin, spinach, beet greens, avocado, bananas, oranges, dried apricots, prunes, tomato paste, salmon, yogurt, milk, and coconut water, with beans, leafy greens, and potatoes generally delivering the most per serving. How much you need, and which sources are safest for you, depends on several factors including kidney function, blood pressure, and medications such as diuretics or ACE inhibitors, so see below to understand more.
If you are seeking out potassium because of symptoms like muscle cramps, weakness, fatigue, constipation, or heart palpitations, food choices alone may not address the underlying cause. A free, instant, online symptom check can help you organize what you are experiencing, surface possible explanations such as low or high potassium, dehydration, or thyroid and kidney issues, and clarify whether this warrants a conversation with a clinician. It takes only a few minutes and gives you clearer language and next steps before your next appointment.
