Potassium is a key mineral element required for a number of cellular functions.
It acts as a vasodilator in blood vessels. Vasodilation in blood vessels can reduce peripheral resistance and increase cardiac output, which can help in normalising blood pressure (BP). In addition, potassium can inhibit the release of renin, which alters the activity of the renin-angiotensin system. Potassium can also control BP by acting on the peripheral and central nervous systems.
High potassium consumption may protect against hypertension. Increasing potassium intake can lower SBP and diastolic BP. Consuming potassium increases its concentration in the intracellular fluid, which tends to draw fluid from extracellular compartments, thereby reducing BP.
