Potassium

Potassium is a mineral that operates primarily inside the cells and is required for normal cell function. Used in a wide variety of body functions, potassium aids in regulating fluid balance and blood pressure, and is involved in neural transmission, muscle contraction and heart function.

Food & Beverage Sources

Foods high in potassium include bananas, cantaloupe, grapefruit, oranges, juices, molasses and potatoes. Beverages such as 100% fruit juice, especially tomato, carrot and orange juice, can also contribute to your daily potassium needs.

Recommended Intake Levels

Although potassium is found in a wide range of foods, especially fruits and vegetables, diets in the U.S. tend to be low in potassium. The potassium recommendation for all adults is 4.7 grams per day, but the average intake for adults in the U.S. is about half that much. During pregnancy, the recommendation remains 4.7 grams per day, but increases to 5.1 grams per day during lactation.
