Potassium ions

Potassium ions are charged particles (positively charged, called cations) that are essential for many bodily functions. They help regulate fluid balance, nerve signals, and muscle contractions, including the heartbeat. Inside and outside cells, potassium ions maintain electrical balance and are involved in transmitting signals throughout the nervous system. The body tightly controls potassium levels through the kidneys and dietary intake to ensure proper functioning and health. Imbalances, whether too high or too low, can affect muscle function, nerve signaling, and heart rhythm, highlighting potassium’s critical role in overall well-being.
