The Abbott Pedialyte Apple Flavor Electrolyte Drink Mild30 in a 500ml bottle is an oral rehydration solution specifically formulated for children to help replenish fluids and electrolytes lost due to conditions like mild diarrhea, vomiting, fever, active play, or exposure to heat. It contains a balanced amount of sodium, potassium, and other electrolytes, along with a mild level of sugar (Mild30 indicates 30 mEq/L of sodium, a lower sodium content compared to some other Pedialyte formulations). This apple-flavored drink is designed to be more effective than water alone in rehydrating and helps prevent dehydration in young children.
