Why Electrolytes Matter
Electrolytes are minerals that carry an electric charge and are essential for many body functions. Sodium helps maintain fluid balance, potassium supports muscle contractions, and magnesium aids in nerve and muscle function. During exercise, you lose electrolytes through sweat, and replacing them is crucial for performance and preventing cramps.
