High-Potassium Foods

Overview

What is potassium?

Potassium is a mineral. It helps keep the right mix of fluids in your body. It also helps your nerves, muscles, and heart work properly.

What foods are high in potassium?

You can control the amount of potassium in your diet by being aware of which foods are low or high in potassium. Foods are high in potassium if they have more than 200 milligrams (mg) per serving.

What foods may contain hidden potassium?

Some foods and drinks may have hidden potassium. Food labels do not have to show the amount of potassium, but some do. Even if potassium is not listed, it may still be in that food.

Potassium may be found in:

  • Diet or protein drinks and diet bars.
  • Sports drinks. These are meant to replace potassium you lose during exercise.
  • Certain herbal or dietary supplements.
