Potassium and magnesium are two of the main minerals in most cells in the body. Potassium is essential for nerve function, muscle strength, glycogen formation, and the regulation of heart action and blood pressure. Magnesium is essential for energy production and storage, muscle relaxation, and the absorption of potassium within the body. Dietary surveys indicate that many people get only 2/3 of the U.S. RDA for magnesium, and the typical American high-sodium diet tends to deplete potassium. K-Mag C™ provides a simple solution to these common dietary imbalances, while providing an excellent source of high quality vitamin C. *
