Sodium isa vital element, which, in contrast to trace elements such asironorzinc, is found not only in "traces" but in larger quantities in the organism. Together with potassium and chloride, it is one of themost important electrolytesIn the mostly high-salt diets of Western countries, a persistent sodium deficiency is less common than an excess supply (hypernatremia).

What functions does sodium have?

The electrolytes sodium, potassium andchloridework as a team. Due to its high water-binding capacity (osmotic activity), sodium, like chloride and potassium, plays an important role in the transmission of nerve impulses,Regulation of water balance, acid-base balance and blood pressure. In addition, at the cellular level, sodium supports the maintenance of membrane potential and the transport of molecules.

Use of sodium

For people who do intensive sports andlose many electrolytes through heavy sweating, a conscious intake of sodium, potassium and chloride is advisable. Sodium intake may also be indicated in the case of illnesses that result in a high loss of sodium. If in doubt, consult your doctor.

* You do a lot of sports,sweat heavilyand drink little?

* You suffer from aacute gastrointestinal inflammation?

* You takehigh doses of diuretic medication(diuretics) with simultaneous high fluid intake?

Symptoms of sodium deficiency(hyponatremia) can be: confusion, loss of appetite, nausea and vomiting. Low blood pressure (hypotension), cardiac arrhythmia (tachycardia) as well as cramps and coma are also among the consequences of a persistent sodium deficiency.
