Potassium is one of seven inorganic, macro mineral nutrients needed in relatively high daily amounts. It is the third most prevalent element in the body after Calcium. Along with Chloride, Sodium, Magnesium, and Calcium, Potassium is an essential electrolyte. These elements are called electrolytes because they carry an electrical charge when dissolved in body fluids. These elements are distributed throughout the body's fluids, including blood, lymph, and interstitial fluids, as well as intracellular fluids. Electrolytes help regulate nerve transmission and many cell membrane functions. Magnesium helps maintain the potassium in the cells; but even more crucial is the proper Sodium to Potassium balance. Without Potassium, cell function will be impacted. Easy on the stomach. Safe for all ages. No color or scent.
