Fact Sheet: Potassium & Heart Health
Potassium and Heart Health
Potassium is a nutrient that is essential for health at the most basic level—it keeps the body’s cells functioning properly. Along with sodium and other compounds, potassium is an electrolyte, working to regulate the balance of body fluids. These actions affect nerve signaling, muscle contraction, and the tone of blood vessels, with far-reaching impacts on the body, including the cardiovascular system.
