Your Care Instructions

Potassium is a mineral. It helps keep the right mix of fluids in your body. It also helps your nerves and muscles work as they should.

Most people get the potassium they need from the foods they eat. But if you have certain health problems, such as kidney disease, you may need to be careful about how much potassium you get. This is because too much potassium can be harmful.

You can control how much potassium you get if you eat foods that don't have much of it and you don't eat foods that have lots of it.
