Potassium plays a vital role in the healthy functioning of various organ systems, particularly in supporting cardiovascular health. It aids in muscle contraction, gastric secretion, renal function, tissue synthesis, and carbohydrate metabolism. As the major cation of intracellular fluid, potassium is crucial for maintaining acid-alkaline balance, isotonicity, and the electrodynamic characteristics of cells. Additionally, it collaborates with sodium to ensure healthy water balance, heart rhythm, and nerve and muscle function, contributing to overall cardiovascular function and blood flow.
