K-Mag C Potas/Mag/Vit C Complex Source Naturals, Inc. 60 Tabs K-Mag C Potas/Mag/Vit C Complex 60 TabletPotassium 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.Suggested Use As a dietary supplement take 1 to 2 tablets twice daily with a meal - Or as directed by your healthcare professional.Supplement FactsServing Size: 2 TabletsServings Per Container: 30Amount Per Serving% Daily ValueVitamin C (as ascorbic acid & potassium ascorbate)1 g1,667%Magnesium (as magnesium chelate)150 mg40%Potassium (as potassium ascorbate & citrate)198 mg6%Percent Daily Values are based on a 2,000 calorie dietOther Ingredients: Stearic acid, hydroxypropyl cellulose, modified cellulose gum, silica, and magnesium stearate.Does Not Contain: Contains no yeast, dairy, egg, gluten, soy, or wheat.
