Your body needs potassium to help your muscles contract, maintain fluid balance, and maintain a normal blood pressure. Normal potassium levels in the body help to keep the heart beating regularly. Potassium may help reduce your risk of kidney stones and also bone loss as you age.
Healthy kidneys keep the right amount of potassium in the blood to keep the heart beating at a steady pace. If you have kidney disease, potassium levels can rise and affect your heartbeat. Be sure to talk with your health professional to determine if you should restrict your intake of foods that contain large amounts of potassium.
Most people do not get enough potassium.
