Potassium has to work with other chemicals like magnesium, it does not help the body alone. In conjunction with sodium, potassium mainly helps regulate the level of water in the body, both of which are partly maintained by the kidneys. A person has to keep a certain amount of water in their body to maintain normal cells. The kidneys regulate how much potassium stays in the body--too much and a person may develop heart problems, like arrythmia, for example.
