Chloride

Chloride is found in many chemicals and other substances in the body. It is an important part of the salt found in many foods and used in cooking. Chloride is needed to keep the proper balance of body fluids. It is an essential part of digestive (stomach) juices.

Too little chloride in the body can occur when your body loses a lot of fluids. This may be due to excessive sweating, vomiting, or diarrhea. Medicines such as diuretics can also cause low chloride levels.

Too much chloride from salted foods can:

• Increase your blood pressure
• Cause a buildup of fluid in people with congestive heart failure, cirrhosis, or kidney disease

Sources

Chloride is found in table salt or sea salt as sodium chloride. It is also found in many vegetables. Foods with higher amounts of chloride include seaweed, rye, tomatoes, lettuce, celery, and olives. Chloride, together with potassium, is also found in most foods and is usually the main ingredient of salt substitutes. Most Americans probably get more chloride than needed, in the form of table salt and salt in prepared foods.

Dosage

How much of each vitamin you need depends on your age and gender. Other factors, such as pregnancy and illnesses, are also important. Women who are pregnant or breast-feeding need higher amounts. Older adults need lower amounts. Ask your health care provider which amount is best for you.
