Potassium Capsules and other Supplements

Potassium supplements may become necessary if your body is deficient in this essential mineral. Potassium serves a number of purposes in the body, and your physician may suggest that you take supplements to ensure that your body can function properly.

What Do Potassium Supplements Do?

In some cases, people don’t receive enough potassium through their diets. A potassium deficiency can have serious health consequences, so it’s important to talk to your doctor about potassium supplements if you have:

  • High blood pressure
  • High cholesterol
  • Heart rhythm problems

Potassium carries a nominal electrical current that helps your nerve cells conduct impulses. Potassium supplements may help your muscles contract (particularly your heart), store carbohydrates, and break down glycogen to provide energy for your brain and nervous system.

Who Should Take Potassium Supplements?

People whose physicians advise potassium supplements should take them. Some people who take diuretics may lose potassium through urine, which means they may need potassium supplements, as well.
