Electrolytes

Explanation:

Minerals that are found in the blood (such as sodium, potassium, and magnesium) are known as electrolytes. A simple definition is that they are minerals which possess or carry an electric charge. They are used to regulate water excretion and retention. When the body's electrolytes are depleted, they are at risk of death because the body is then unable to regulate its osmotic needs.
