Potassium chloride is a mineral supplement used to treat or prevent low levels of potassium in the blood.
The supplement, often referred to as the formula KCl, is available from dozens of manufacturers.
Potassium is essential for the function of the heart, muscles, kidneys, nerves, and digestive system. Typically, a well-balanced diet supplies all the potassium you need.
However, certain diseases, conditions, or drugs can remove potassium from the body. Potassium depletion may be caused by:
Excessive vomiting or diarrhea
Diabetic ketoacidosis caused by extremely high blood sugar
Adrenal gland disorders
Certain gastrointestinal conditions
