Q. I read that potassium is absolutely crucial to reduce hypertension. It suggested 4,700 mg of potassium daily. I don’t think I can eat enough bananas and potatoes to get this much potassium. Is there an over-the-counter supplement I could take?
A. We don’t recommend OTC potassium supplements because you might overdose. This is as dangerous as too little. If you are eating plenty of vegetables and fruits, you are probably getting more potassium than you realize.
