Potassium: Nutrition, Pros & Cons
Potassium is an essential mineral and major intracellular electrolyte critical for maintaining cellular fluid balance, nerve conduction, and normal muscle function. Under Indian dietary guidelines, achieving an adequate intake of potassium is highly emphasized to offset the adverse cardiovascular effects of high sodium consumption.
