Potassium is necessary for the normal functioning of all cells, important to both cellular and electrical function. It is one of the main electrolyes in the body (along with Sodium and Chloride) which means it carries a tiny electrical charge. Hence its chemical symbol is K+. On a side note, in homeopathy all remedies made with Potassium have ‘Kali’ in their name.
It regulates the heartbeat, ensures proper function of the muscles and nerves, and is vital for synthesizing protein and metabolizing carbohydrates. It is the primary positive ion (cation) found within the cells, where 98 percent of the 120 grams of potassium contained in the body is found.
Potassium is present in all body tissues and is required for normal cell function. Most potassium is contained within the cells (intracellular). Interestingly, Magnesium helps maintain the potassium in the cells, but the sodium and potassium balance is as finely tuned as those of calcium and phosphorus or calcium and magnesium. More on those minerals in the weeks to come!
