The amount of chloride in the human body is about 100 grams. The body’s chloride balance is closely linked to its sodium and potassium balance.
Chloride is absorbed by the body through salt intake for the most part, because salt is made up of half sodium and half chloride. Naturally occurring chloride in foods accounts for only about 10% overall.

Functions in the Body

  • Contributes to normal digestion
  • Influences the hydrochloric acid production in the stomach
  • Aids in regulating the body’s acid base balance
  • Vital for osmolarity (regulating fluid content balance among cells)

Deficiency Symptoms

  • Low blood pressure
  • Persistent higher pulse rate
  • Growth disorders


A high chloride level is usually related to a high sodium intake. Observed symptoms can be disorders of the cardiovascular system, increase in blood pressure, functional disorders of the muscles and digestive problems. It is still unclear whether chloride or sodium causes these symptoms.
