Potassium is necessary for the body to function properly, but too much potassium in the blood can cause a lot of problems. Elevated potassium occurs either because the body cannot eliminate the excess effectively or because a condition or symptom is causing too much to be released into the bloodstream. Managing potassium levels is particularly important for people with kidney and heart problems, but many factors contribute to how much potassium is in the blood.

The right amount of potassium can also help counter the negative effects of sodium on cardiovascular health.
