Potassium

​​

1. Why is this mineral important?

Potassium is a vital mineral and electrolyte that plays a central role in many bodily functions. It is essential for maintaining fluid balance, muscle and nerve function and the regulation of blood pressure. Potassium also helps to stabilise the body's acid–base balance.

 

 

 

 

 

 

 

 

 

 

2. What do we need this mineral for?

Potassium is needed for: Cardiovascular system: regulates blood pressure and supports healthy heart function. Nerve and muscle function: required for the transmission of nerve impulses and for muscle contraction. Fluid and electrolyte balance: helps to maintain the balance of fluids in the cells. Acid–base balance: contributes to maintaining a stable pH in the body.

 

3. Signs of a deficiency of this mineral in the body

A potassium deficiency (hypokalaemia) can show itself through the following symptoms: muscle cramps and weakness, fatigue and exhaustion, cardiac arrhythmias, constipation or digestive problems, tingling or numbness in the extremities.

 

4. Possible consequences of a deficiency

A long-term potassium deficiency can cause serious health problems, including: High blood pressure: a low potassium level can contribute to increased blood pressure. Cardiac arrhythmias: insufficient potassium levels can lead to heart problems. Muscle weakness and paralysis: severe hypokalaemia can severely impair muscle function. Kidney problems: insufficient potassium intake can disturb kidney function.

 

5. Requirement and recommendation

The recommended daily intake of potassium varies depending on age and sex. General recommendations are: adults: 3,500–4,700 mg per day; children and adolescents: 2,000–3,000 mg per day, depending on age. Good sources of potassium are: Fruit and vegetables: bananas, potatoes, spinach, avocados, oranges and tomatoes. Pulses and nuts: beans, lentils, almonds and walnuts. Dairy products and fish: yoghurt, salmon and tuna. Mineral water: some mineral waters contain potassium in natural form. A balanced potassium status is crucial for health. However, excessively high potassium levels (hyperkalaemia) can also be problematic, especially in people with impaired kidney function. If needed, or in case of a deficiency, we recommend our medicinal and mineral waters – ideally, however, this should be discussed with a doctor.
