The level of potassium contributed from potassium chloride softened water is safe for normal healthy people. For healthy individuals, potassium from the diet is absorbed slowly from the gastrointestinal tract and the excess potassium is excreted. However, in certain individuals with medical conditions such as kidney disease, diabetes, heart disease or high blood pressure, the body may not excrete excess potassium. Individuals with these conditions must consult a doctor prior to consuming potassium-softened water. If you have any questions as to whether your health condition allows you to use potassium based water softener products, please consult your doctor.
