Who Should Not Take Potassium Supplements?
Potassium deficiencies can cause serious problems including muscle weakness, stroke, high blood pressure and osteoporosis, but not everyone is a candidate for potassium supplements. Certain drugs and kidney problems, especially, can inhibit the body's absorption of potassium; taking a supplement may cause a potentially fatal overdose. As with any drug, check with your doctor if you are currently on prescription medications or have an existing chronic condition.

Some diuretics are designed to spare potassium in the blood, so someone taking diuretics should not add potassium supplements.
Overdose
-
Symptoms of a potassium overdose include low blood pressure, irregular heartbeat, stomach pain, confusion, weakness or tingling in the arms or legs, and coma. Get emergency help immediately.
Diet
-
Consider a dietary change as an alternative to potassium supplements. A low-sodium diet with plenty of tomatoes, potatoes, avocados, bananas, citrus fruits, unsalted nuts, milk, yogurt, cottage cheese, and green, leafy vegetables will provide plenty of potassium.
