General information for Chloride

The chloride ion is a negatively charged ion that is formed when the element chlorine gains an electron. Chloride is formed e.g. when hydrogen chloride is dissolved into water. Chlorine in its elemental form is a poisonous gas. Chlorine combined with sodium, potassium or hydrogen becomes chloride. Chloride is commonly found e.g. in salt (NaCl).

Benefits of Chloride

Helps to maintain fluid balance and electrolyte balance. Chloride is part of the hydrochloric acid in your stomach (HCl). This is vital to good digestion.

Deficiency symptoms / disease

Hypochloremia is an electrolyte disturbance in which there is too low a level of the chloride in the blood.


Overdose symptoms / disease

Hyperchloremia is an electrolyte disturbance in which there is too high a level of the chloride in the blood.


FDA facts for Chloride

(Daily value/Recommended dietary allowance/Adequate intake)

Recommended intakes of nutrients vary by age and gender and are known as Recommended Dietary Allowances (RDAs) and Adequate Intakes (AIs). However, one value for each nutrient, known as the Daily Value (DV), is selected for the labels of dietary supplements and foods. A DV is often, but not always, similar to one's RDA or AI for that nutrient. DVs were developed by the U.S. Food and Drug Administration (FDA) to help consumers determine the level of various nutrients in a standard serving of food in relation to their approximate requirement for it. The label actually provides the %DV so that you can see how much (what percentage) a serving of the product contributes to reaching the DV.

Food sources for Chloride

Table salt, sodium chloride (NaCl), has chloride in it. Sodium chloride is found in many foods so it is unlikely that you are not getting enough chloride.

Deficiency of chloride is rare but temporarily due to sweating, diarrhea or vomiting there may be a loss of chloride.
