What is Potassium?

What Is the Density of Potassium

Potassium is a macromineral that the body needs in fairly large doses. The other macrominerals include sodium, magnesium, chloride, sulfur, calcium, and phosphorous. [3] Potassium is also an electrolyte, meaning that it breaks down into ions in solution and has the ability to conduct electricity within the body. [4]

Potassium’s Role in the Body

Who Discovered Potassium - Electrolysis

Potassium and sodium work together to help maintain normal cell fluid levels. Potassium maintains normal fluid levels within the cells, while sodium works to maintain normal fluid levels outside of cells. This supports normal blood pressure and helps muscles to contract. [5]
