What Does Potassium Do?

Potassium is found in all of the tissues in the human body. Along with sodium, potassium is a key electrolyte, a substance that helps to conduct energy through the body. Without potassium, your kidneys, heart, muscles and nerves cannot function properly.

Potassium Deficiency

Your body cannot manufacture potassium on its own. As a result, you can only obtain the mineral by eating foods that contain it. Food sources of potassium include dried apricots, prunes, raisins, bananas, potatoes, spinach, tomatoes, broccoli, beans, nuts, dairy products, meats, poultry and fish. Individuals with digestive disease and those on certain medications are at an increased risk for low potassium levels. Potassium supplements may be recommended for anyone who has or is likely to develop a potassium deficiency.

Potassium Benefits

Scientific research suggests that potassium may be beneficial for people who have or are at risk for developing certain medical conditions. Medical professionals may recommend potassium supplements for promoting heart and bone health, managing type 2 diabetes and lowering the likelihood of kidney stones. It's important to understand that there is not enough evidence to prove that potassium supplements are beneficial for addressing any medical condition.

Potassium Side Effects

Potassium supplements can pose a risk for side effects and interfere with some medications and other dietary supplements.
