Potassium
supplementMinerals / electrolytes
Research status · Dietary supplement
Dietary supplement / essential electrolyte; OTC supplement doses are intentionally small.
An electrolyte most people under-consume relative to sodium. Food (fruit, vegetables, dairy) is the primary source; supplements are capped at small doses because too much potassium is genuinely dangerous, especially with kidney issues or certain medications.
How it works
Principal intracellular electrolyte — nerve conduction, muscle contraction, fluid balance, and blood-pressure regulation.
Commonly discussed use cases
- Electrolyte balance
- Heavy sweating (with clinician guidance)
- Low-carb diets (discussed)
Supposed / potential benefits
- Supports normal fluid balance and muscle function when intake is low
Common side effects
- GI upset
Warnings & contraindications
- Dangerous in kidney disease and with potassium-sparing medications (some blood-pressure drugs) — clinician conversation required
Typical timing considerations
With food and fluids; follow product guidance.
Administration route
Oral
Questions to ask your clinician
- Given my kidneys/medications, is supplemental potassium safe for me?
- Should I get it from food instead?
