Calcium is the most plentiful mineral in the human body, with approximately 99 percent of it occurring in bone tissue, and the remaining one percent being used for a variety of other functions, including blood clotting, muscle contraction, and nerve function. Healthy teeth and bones both depend on adequate calcium supply, and calcium also contributes to healthy skin, helps regulate cardiovascular function and blood pressure levels, aids in the metabolism of iron, and is required for proper cell division.

Calcium must be daily supplied to the body through the diet or supplementation.
The best food sources of calcium include milk, yogurt, cheese, cottage cheese, dark green leafy vegetables, broccoli, turnip and collard greens, salmon, sardines, canned fish, almonds, and brazil nuts. The standard American diet is estimated to supply only one-third of our daily calcium needs.

Chloride is an essential part of hydrochloric acid (HCl), a vital stomach digestive acid, and also plays a role in regulating the body's acid-balance. It is also useful in helping the liver eliminate toxins, and for transporting carbon dioxide to the lungs for excretion. Among the best food sources of chloride are salt, seaweeds, celery, lettuce, and tomatoes.
