The salt content listed in the nutritional information is calculated based on the sodium content, as required by law. Other minerals are not included in the nutritional declaration, although they are equally important for maintaining a normal fluid balance.
In addition to the mineral sodium, Refuel Sports Drinks contain potassium, calcium, magnesium, and chloride – all naturally derived from whey.
To maintain a normal fluid balance, our body needs electrolytes. Electrolytes are minerals that carry an electric charge when dissolved in a fluid such as blood. The electrolytes in the blood – sodium, potassium, chloride, and bicarbonate – help regulate nerve and muscle function and maintain the body's acid-base balance and water balance.
In other brands, sodium is often added primarily in the form of table salt (sodium chloride or NaCl), and the additional electrolytes are provided as industrially manufactured salts. The sodium content in these products is often higher than in our products, which is why the salt content appears higher in their nutritional information.
What truly matters for function and for maintaining fluid balance (hydration) is not the salt content, but the total electrolyte content.
