How Much Potassium Should You Take in Per Day?

People 14 years of age or older should consume 4,700 milligrams of potassium per day. The recommended intake for women who are breastfeeding is 5,100 milligrams per day.

Potassium is essential for normal heart function, digestion and muscle contraction. This mineral is found in orange juice, bananas, potatoes, tomatoes, chicken, salmon and cantaloupe. Although potassium is necessary for survival, people with kidney disease must limit their intake of potassium because damaged kidneys do not do a good job of removing the mineral from the blood. Someone following a potassium-restricted diet should consume approximately 2,000 milligrams per day, as suggested by the National Kidney Foundation. The limit may be higher or lower depending on a person's blood test results and overall health.
