The Mineral Potassium

Vital to our Body

The body of an adult contains approximately 130 grams of potassium (K) – with nearly 98% present inside the body’s cells. Potassium is one of the most important electrolytes in our body fluids. It is responsible for maintaining osmotic pressure in the cells, and for transmitting stimuli to muscle and nerve cells. It is indispensable for the creation of protein, for glucose transport and also affects the insulin metabolism. Potassium plays an important role in blood pressure regulation, the water balance and the acid-base balance.


It is present in every cell of the body, and assures its proper fluid balance.


But potassium is also required for the creation of the body’s own proteins, for the utilisation of carbohydrates and for muscle functions.


Potassium deficiency may produce the following symptoms: fatigue, exhaustion, amyosthenia and constipation. More serious cases may even show as impaired consciousness and cardiac arrhythmia.


Potassium deficiencies may be caused by the following:

  • insufficient potassium intake
  • frequent use of laxatives and diuretics
  • chronic kidney or gastro-intestinal disorders
  • excessive loss of body fluids or medication
  • magnesium deficiency
  • acidemia
  • diabetic ketoacidosis

A Minimum of 2 Grams per Day

Potassium is one of the essential elements of the body. It is absolutely vital, but cannot be produced by the organism itself. It is therefore necessary to supply potassium as part of the daily diet. The Deutsche Gesellschaft für Ernährung (DGE – German association for nutrition) recommends a minimum of 2 grams per day, for adults. The WHO even suggests a minimum daily intake of 3.5 grams. In the U.S., the Food and Drug Administration (FDA) of the Ministry of Health as well as the Institute of Medicine (IOM) recommend 4.7 grams per day.
