Sports and energy drinks are both fine for kids.
This isn’t completely true.
Sports and energy drinks both contain ingredients usually best avoided in children...large amounts of sugar and high doses of caffeine. The American Academy of Pediatrics says they aren’t a good idea for most kids.
Sports drinks (Gatorade, etc) contain carbohydrates and electrolytes and some throw in vitamins and minerals. They’re marketed for hydration in people who exercise.
