Potassium and Blood Pressure Regulation: Renal Physiology, Vascular Effects, and Dietary Sources
Potassium is a major intracellular cation that is essential for neuromuscular function, cardiac electrophysiology, and the regulation of fluid and acid–base balance. In the cardiovascular context, potassium is clinically important because it counterbalances sodium-driven volume expansion and modulates vascular tone. Epidemiologic and interventional data consistently associate higher dietary potassium intake with lower blood pressure, particularly… Read More »
