Sodium
1. Why is this mineral important?
Sodium is an essential mineral and an important electrolyte in the body. It plays a central role in regulating water balance, nerve function and muscle contraction. Sodium is also crucial for blood pressure and the acid–base balance. It is mainly obtained through food, above all in the form of table salt (sodium chloride).
2. What do we need this mineral for?
Sodium is needed for: Fluid balance: regulates the body's water content and supports kidney function. Nerve function: important for signal transmission in the nerves and between cells. Muscle contraction: supports the normal function of muscles, including the heart muscle. Acid–base balance: contributes to stabilising the body's pH value. Blood pressure regulation: plays a role in maintaining blood pressure but should be consumed in moderation.
3. Signs of a deficiency of this mineral in the body
A sodium deficiency (hyponatraemia) can be caused by excessive sweating, high fluid intake or illness and shows itself through: fatigue and weakness, headaches, dizziness or low blood pressure, muscle cramps or twitching, nausea and vomiting, confusion or concentration problems.
4. Possible consequences of a deficiency
A longer-term sodium deficiency can cause serious health problems, such as: Dehydration: the body's water balance is thrown off. Disorders of the nervous system: impaired nerve communication, which in severe cases can lead to seizures. Collapse or shock: a severe sodium deficiency can lead to loss of consciousness and circulatory failure.
5. Requirement and recommendation
The recommended daily intake of sodium varies depending on age and life situation. General recommendations are: adults: 1,500 mg per day (a maximum of 2,300 mg per day is recommended); children and adolescents: 1,000–1,500 mg per day, depending on age. Sodium is contained in many foods, especially in processed products, cheese, bread and sausages. Balanced consumption is important, as excess sodium can increase the risk of high blood pressure and cardiovascular disease. If needed, or in case of a deficiency, we recommend our medicinal and mineral waters – ideally, however, this should be discussed with a doctor.
