What are normal potassium levels?

3.6-5 meq/L: Milliequivalent per liter or millimol/liter (mmol/l). If you live outside the us in a country that uses milligram/dl the number will be different. You need to know your potassium since it is very important if you have kidney disease.

Blood potassium: In blood, the normal range is 3.6 mg/dL to 5.4 mg/dL. Labs that run these tests typically report a normal range. If you look at a group of healthy individuals, the potassium level in the vast majority will fall between 4.0 to 4.4.
