Chloride regulates the water and electrolyte balance and is vital for the formation of stomach acids.
Chloride: In Depth
The human body contains about 120 g of chloride. Chloride, like sodium, is dissolved in the extra cellular fluids and is vital for the maintenance of the acid-base balance. Chloride regulates the water balance and electrolyte neutrality along with potassium and sodium. It is a component of brain and spinal-cord fluids as well as digestive juices e.g. it forms stomach acids with hydrogen which are important for digestion. (HCl).
Chloride: Requirements, deficiency and oversupply
Similar to sodium deficiency, a chloride deficiency can be caused by excessive sweating or constant vomiting which can lead to malfunctioning of the acid-base balance, muscle cramps and heart problems.
Excessive chloride is excreted with the help of the kidneys.
Chloride in Foods
Chloride is usually consumed in the form of cooking salt (NaCl) which also contains sodium.
