Potassium
An electrolyte that keeps heart rhythm, muscle contraction, nerve signals, and fluid balance working. Food is the main source, and supplements need more care than most minerals.
Commonly used for
- Low potassium from diet, sweating, or certain diuretics (as directed)
- Blood pressure support, mainly through diet
- Electrolyte replacement with heavy sweating
- Muscle cramps from low electrolytes
Found naturally in
- Potatoes and sweet potatoes
- Beans and lentils
- Avocado
- Leafy greens
- Coconut water
Label red flags
- Salt substitutes, which are mostly potassium chloride and add up quickly
- Several electrolyte drinks or powders used together
Check with a provider
- Kidney disease. The kidneys clear potassium, and levels can build up to a dangerous point.
- Taking ACE inhibitors, ARBs, potassium-sparing diuretics (such as spironolactone), or trimethoprim, which all raise potassium
- Heart rhythm problems or heart failure
- Signs of high potassium: muscle weakness, tingling, or an irregular or slow heartbeat. Seek care right away.
- Trouble swallowing or slow stomach emptying. Potassium pills can irritate the throat and gut.
