Electrolytes are minerals: sodium, potassium, calcium, magnesium, and chloride. What makes them unique is their ability to acquire an electrical charge when they come into contact with a fluid in the body, such as water or blood. This is why they’re called electrolytes, and it’s what allows them to transmit electrical signals throughout the body—signals that are essential for numerous physiological functions.
It is difficult to estimate our electrolyte requirements, as they vary depending on factors such as age, sex, physical activity levels and outdoor temperature. Electrolytes also interact with one another, meaning that a deficiency in one mineral can affect the absorption of another.
In general, sodium intake should be limited, while potassium requirements are usually met through a balanced and varied diet. Calcium intake is also generally sufficient, although children and pregnant or breastfeeding women have higher requirements.
As for magnesium, some estimates suggest that a significant proportion of the population may have insufficient levels. This can partly be explained by the fact that stress can increase the body's needs for magnesium and contribute to greater losses through urine. Stress can also lead to increased sweating, which may further contribute to mineral loss. Learn more about electrolytes
