Potassium is an essential dietary mineral and electrolyte found in many foods particularly vegetables, fruits, citrus juices, dairy products and whole grains.
Why is there potassium in some foods and beverages?
Some foods and beverages are made with ingredients such as milk and other dairy products, which contain naturally occurring potassium. Other products are made with ingredients that contain very small amounts potassium. Examples include the low-calorie sweetener acesulfame-potassium (ace-K) and potassium sorbate, which is used to protect the freshness and flavors of some foods and beverages.
Should I be concerned about getting too much potassium?
