What are the 4 electrolytes?

- Sodium (Na+): Sodium is the most abundant extracellular electrolyte and plays a vital role in maintaining fluid balance, nerve conduction, and muscle contraction. It is primarily found in sodium chloride (salt) and is obtained through dietary sources. (Source: Sharma, A., Madaan, V., & Petty, F. D. (2021). Anatomy, Abdomen and Pelvis, Cholera. In StatPearls Internet. StatPearls Publishing.) - Potassium (K+): Potassium is the major intracellular electrolyte and is crucial for numerous physiological processes including muscle contraction, nerve impulses, and maintaining normal heart rhythms. It is obtained through various dietary sources like fruits, vegetables, and legumes. (Source: Azad, M. H., Akhter, M. S., & Akter, M. (2021). Potassium, Physiology. In StatPearls Internet. StatPearls Publishing.) - Calcium (Ca2+): Calcium is an essential electrolyte involved in bone formation, muscle contraction, nerve conduction, blood clotting, and various enzymatic reactions. Adequate levels of calcium are obtained through diets rich in dairy products, certain vegetables, and fortified foods. (Source: Horwitz, M. J., Stewart, A. F., & Rosen, C. J. (2021). Calcium and Phosphorus Homeostasis. In Williams Textbook of Endocrinology (14th ed.). Elsevier.) - Magnesium (Mg2+): Magnesium serves as a cofactor for more than 300 enzymatic reactions in the body, and it is involved in muscle and nerve function, protein synthesis, blood pressure regulation, and bone health. It is obtained through dietary sources like green leafy vegetables, nuts, seeds, and whole grains. (Source: Swaminath, M. (2021). Magnesium. In StatPearls Internet. StatPearls Publishing.)
