Foods high in potassium - Dr. Axe

There are so many reasons you need to make sure you consume an adequate amount of potassium-rich foods daily. An important electrolyte, potassium is also the third most abundant mineral in the body. It interacts with sodium to perform a number of important functions every single day, such as balancing fluids and mineral levels within the body.

  • 1–3 years: 2,000 milligrams/day
  • 4–8 years: 2,300 milligrams/day
  • 9–13 years: 2,500 milligrams/day for males and 2,300 milligrams/day for females
  • 14–18  years: 3,000 milligrams/day for males and 2,300 milligrams/day for females
  • Over 19 years: 3,400 milligrams/day for males and 2,600 milligrams/day for females
