In this Review, the authors discuss the physiological determinants of blood potassium levels, the health consequences of chronic hypokalaemia and hyperkalaemia, and the potential cardiorenal benefits of potassium supplementation. They also highlight strategies to reduce the risk of hyperkalaemia and enable patients with chronic kidney disease to consume a potassium-rich diet.
