Potassium
Potassium requires 2600 mg daily for adult women and 3400 mg for men. It has 2 severe interactions, notably with Potassium citrate and Potassium citrate.
What Potassium does
Principal intracellular cation; sets resting membrane potential and blood pressure.
No UL for healthy adults from food. Supplemental potassium interacts with ACE inhibitors and potassium-sparing diuretics.

Interactions involving Potassium
4 sourced rules| Pair | Severity | Mechanism | Action |
|---|---|---|---|
| Potassium citrate × ACE inhibitor | Severe | ACE inhibitors reduce aldosterone-driven potassium excretion. Adding potassium supplements can push serum potassium into the hyperkalaemic range, which risks cardiac arrhythmia. | Do not supplement potassium without your prescriber’s approval on an ACE inhibitor. Get potassium and creatinine checked.Source |
| Potassium citrate × Potassium-sparing diuretic | Severe | Potassium-sparing diuretics retain potassium by the same mechanism, so supplemental potassium stacks dangerously. | Avoid potassium supplements with potassium-sparing diuretics unless explicitly prescribed and monitored.Source |
| Potassium citrate × Magnesium glycinate | Mild | Both are cations handled by overlapping renal and intestinal transport; combined high doses can add to electrolyte shifts. | Take them at separate times and monitor if you have kidney disease or take diuretics.Source |
| Apple cider vinegar × Potassium citrate | Mild | Apple cider vinegar can lower potassium levels, which opposes supplemental potassium and can worsen depletion. | Avoid combining large daily amounts of apple cider vinegar with potassium supplements.Source |
