Electrolytes are minerals that carry an ionic charge such as sodium, potassium, calcium, chloride and magnesium. Electrolytes are found in body fluid, tissue and blood and are critical to help maintain the body’s fluid balance, regulate muscle contractions, and transmit nerve impulses.
Why do sports drinks contain electrolytes?
Your body sweats to cool itself down. When this happens, you don't just lose water, you also lose vital electrolytes, particularly sodium. The sodium and other electrolytes in sports drinks like Gatorade, and other beverages like Propel, help to replace the electrolytes lost in sweat. Electrolyte replacement is especially important when exercising for prolonged periods of time or in hot and humid climates.
What are the electrolytes in Gatorade Thirst Quencher?

Are there electrolytes in other foods and beverages?
Yes, fruit juices, coconut milk and many whole fruits and vegetables (e.g. potatoes, avocados) contain various electrolytes in different amounts. However, they are not specifically formulated for electrolyte replacement or with the athlete in mind.
