NOW Foods Potassium Gluconate Powder provides potassium in the gluconate form — one of the most water-soluble and well-tolerated forms of supplemental potassium — in a convenient powder that allows for flexible, precise daily dosing. Potassium is the primary intracellular electrolyte in the human body, essential for maintaining normal blood pressure, heart rhythm, muscle contraction, nerve function, and fluid balance. Most adults do not meet the adequate intake for potassium through diet alone, particularly those eating a Western diet low in fruits and vegetables. Supplemental potassium supports healthy blood pressure by counteracting sodium's effects on blood vessel tone. NOW Foods provides potassium gluconate powder in a 1 lb container for economical daily supplementation. Note: potassium supplements are regulated at 99 mg per serving by FDA guidelines — use as directed.
