What is potassium?
Potassium is an essential mineral and belongs to the group of macrominerals. It is a central component of the body's electrolytes. Potassium is especially indispensable for the functioning of nerve and muscle cells. The body cannot produce potassium on its own – it must be supplied regularly through food.
Functions and benefits of potassium
- Potassium contributes to the maintenance of normal blood pressure.
- Potassium supports the normal functioning of the nervous system.
- Potassium is important for normal muscle function.
These statements are approved according to the EU Health Claims Regulation. A balanced potassium level is thus crucial for many important body functions.
Potassium in food
Good sources of potassium include bananas, potatoes, spinach, avocado, and legumes. Those who eat a balanced diet can usually meet their needs well. In cases of an unbalanced diet or certain life situations, supplementary intake may be useful.
Dosage and use – what beginners should know
The recommended daily intake for adults is about 4,000 mg according to the DGE. This value is usually reached with a varied diet. You should only use potassium supplements after consulting a healthcare professional, especially if you have existing health conditions or are taking medication.
Practical example
For example, increased sweating after exercise or on hot days can raise potassium requirements, since electrolytes are lost through sweat. A particularly salt-rich diet can also affect the balance.
Good to know: Potassium and other nutrients
Potassium works closely in the body with other electrolytes such as chloride and magnesium. A balanced ratio is important for optimal function. Learn more about the relationship between nutrients and their functions in the body.
