Potassium (Citrate)
Critical electrolyte for heart rhythm, muscle contractions, and fluid balance. Most adults do not get enough from diet alone.
Projected serum levels — 99 mg, once daily
Maintenance schedule: 99 mg once daily (oral).
Loading schedule: 297 mg on day 1, then 99 mg once daily — reaching therapeutic levels sooner.
Modeled steady state after ~38 days: peak ≈ 1.8k mg, trough ≈ 1.7k mg body load. Population-based estimate over 106 days for a 99 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.

Documented interactions
-
danger
Spironolactone (Anti-Androgen) + Potassium (Citrate)
Spironolactone is potassium-sparing. Combined with potassium supplements risks dangerous hyperkalemia.
-
warning
Combined OC (Drospirenone / Ethinyl Estradiol) + Potassium (Citrate)
Drospirenone has anti-mineralocorticoid activity (potassium-sparing). Combining with potassium supplements can cause hyperkalemia.
-
warning
Lisinopril + Potassium (Citrate)
ACE inhibitors reduce potassium excretion. Supplementing potassium on top risks dangerous hyperkalemia.
