Potassium is the third most common mineral in the body (first and second are calcium and phosphorus). And even more: together with sodium and chloride potassium is one of the most important electrolytes for the organism. Electrolytes are electrically charged minerals that are vital for the fluid balance of the body.
They are vital for maintaining healthy blood pressure and muscle contractions; they also support the healthy function of nerves and kidneys. In general, these three electrolytes are an integral element for every chemical process in the human organism. Potassium also participates in the transformation of blood sugar into glycogen.
