Potassium


Potassium is a mineral that’s crucial for life. Potassium is necessary for the heart, kidneys, and other organs to work normally.

Why do people take potassium?

Most people who eat a healthy diet should get enough potassium naturally. Low potassium is associated with a risk of high blood pressure, heart disease, stroke, arthritis, cancer, digestive disorders, and infertility. For people with low potassium, doctors sometimes recommend improved diets — or potassium supplements — to prevent or treat some of these conditions.

  • Potassium deficiencies are more common in people who:
  • Use certain medicines, such as diuretics
  • Have physically demanding jobs
  • Athletes exercising in hot climates and sweating excessively
  • Have health conditions that affect their digestive absorption, such as Crohn’s disease
  • Have an eating disorder
  • Smoke
  • Abuse alcohol or drugs

How much potassium should you take?

The Institute of Medicine has set an adequate intake for potassium. Getting this amount of potassium from diet, with or without supplements, should be enough to keep you healthy. The FDA has determined that foods that contain at least 350 milligrams of potassium can bear the following label: “Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke.”
