I supplement with 100 mg potassium daily-- too much? when i eliminate it i get leg cramps.

Requires lab: How much potassium you need depends on your blood tests, kidney function, and other medications. The only way to know the correct amount is by lab tests which will have to be monitored by your doctor. Too much or too little potassium cns be very dangerous. If you get leg cramps when not taking your potassium chances are good you need this supplement.

Not too much: Potassium is usually dispensed as potassium chloride or potassium citrate. 100 mg usually refers to the weight of the salt. Physicians usually put patients on 10 to 20 meq of potassium as a supplement if needed. 10 meq of potassium = 1,080 mg of potassium citrate or 750 mg of potassium chloride.
