Electrolyte

Salts and minerals such as Na⁺,  K⁺, Ca²⁺, and Mg²⁺ are dissolved in our blood and are known as electrolytes. Electrolytes carry a charge, which can be negative or positive. When electrolytes are dissolved in water, the solution can conduct electricity. They are vital for normal body functioning and are particulary important in muscle and neurone function. If electrolytes are present in the wrong concentrations then it can causes an electrolyte imbalance and the symptons can include weakness, twitching and in extreme circumstances seizures. The kidneys keep electrolyte levels constant to try and avoid an imbalance as they filter out the excess.
