What are electrolytes?
Electrolytes are compounds that carry a charge when dissolved in water. Well-known electrolytes are sodium, potassium, chloride, calcium and magnesium. You get electrolytes from food.
What do electrolytes do?
The body uses electrolytes to create an electrical charge difference. Nerve cells use this electrical charge to send signals; muscles to contract.
You also need electrolytes to maintain water balance. The body cannot actually absorb water the way it does food. Instead, the body uses electrolytes to attract water.
