The mineral sodium is found in all cells and bodily fluids. It is closely related to chloride. Both are vital and an essential part of the electrolyte balance. They are important for the maintenance of various cell and bodily functions (e.g. regulation of fluid volume, blood pressure and the acid-base balance). Chloride is also found in the digestive juices, especially in the stomach (hydrochloric acid). Sodium helps to keep the fluids in normal balance (water in the body). Sodium plays an essential role in the normal functioning of nerves and muscles.
