Dr. Axe has some wonderful information on electrolytes:
The major electrolytes found within the body include calcium, magnesium, potassium, sodium, phosphate and chloride. Because these crucial nutrients help stimulate nerves throughout the body and balance fluid levels, an electrolyte imbalance can cause a variety of serious negative symptoms, including some that are potentially deadly.
You obtain electrolytes through eating different foods and drinking certain fluids, while you lose them partially through exercise, sweating, going to the bathroom and urinating. This is why a poor diet, too little or too much exercise, and being sick are some possible causes for an electrolyte imbalance.
Some of the major roles that electrolytes have within the body include:
- Calcium: helping with muscle contractions, nerve signaling, blood clotting, cell division, and forming/maintaining bones and teeth
- Potassium: helping keep blood pressure levels stable, regulating heart contractions, helping with muscle functions
- Magnesium: needed for muscle contractions, proper heart rhythms, nerve functioning, bone-building and strength, reducing anxiety, digestion, and keeping a stable protein-fluid balance
- Sodium: helps maintain fluid balance, needed for muscle contractions, and helps with nerve signaling
- Chloride: maintains fluid balance
