Electrolytes are electrically charged minerals

Horses depend on certain electrically charged minerals to maintain the balance and flow of vital body fluids, the transmission of nerve impulses and the healthy function of the muscles and the circulatory system. These minerals are called electrolytes. Their positive and negative charges help to control the body’s pH (acid/base) balance and the transport of nutrients and waste products in and out of the cell. The minerals sodium, potassium, chloride, calcium, and magnesium collectively are termed electrolytes.
