Potassium is an essential nutritional component that regulates blood pressure, fluid equilibrium and muscular activity. Adequate potassium levels in the body may also lower the likelihood of developing kidney stones and delay the onset of bone loss, commonly associated with the aging process.
Age is one of the factors that determine the daily amount of potassium necessary to maintain good health. Adolescents and adults share the same daily requirement for this mineral, notes the U.S. Food and Drug Administration.
