It is extremely reactive in water and is categorized as an electrolyte. It produces positively charged ions when dissolved in water. It has a unique feature that allows it to conduct electricity, which is critical for many bodily activities. A potassium-rich diet has been linked to a slew of substantial health advantages. It may aid in the reduction of blood pressure and water retention, as well as the prevention of osteoporosis and kidney stones [1].

Potassium-dense foods include fruits like apricots, bananas, kiwis, oranges, and pineapples. Leafy greens, carrots, and potatoes are examples of vegetables, meats that are low in fat, whole grains, legumes, and nuts [2].

For normal cellular activity, the total body potassium concentration and proper potassium distribution across the cell membrane are crucial. Potassium homeostasis is maintained in a variety of ways. Total body potassium content is determined in the kidney by changes in potassium excretion in response to changes in intake.

Insulin and beta-adrenergic tone are important in maintaining potassium distribution within the body under normal circumstances. A sodium-potassium ATPase exchanger is found in all cells, and it pumps Na+ out of and K+ into the cell.


This resulting in a K+ gradient across the cell membrane (K+in > K+out), which is partially responsible for maintaining the membrane potential. The correct operation of excitable tissues like nerves and muscle depends on maintaining this gradient [3].
