Chloride Ion

Chloride is a salt and electrolyte consisting of two elements, one of which is chlorine. It makes up about 0.15 percent of the body weight and is found mainly in the fluid outside cells. As one of the mineral electrolytes, chloride works closely with sodium and water in the distribution of body fluids.

In addition to table salt or sea salt (sodium chloride), vegetables are a common source of chloride. Foods with higher amounts of chloride include seaweed, rye, tomatoes, lettuce, celery, and olives. Potassium chloride is found in most foods and is usually the main ingredient of salt substitutes.
