Electrolyte drinks vs sports drinks: what is the difference?
They are built for different jobs, and the difference is mostly sugar.
Sports drinks
Designed for endurance exercise, where the goal is delivering carbohydrate as fuel alongside fluid. The sugar is the point. A typical bottle carries a meaningful amount of it, which is useful mid-marathon and not useful at a desk.
Electrolyte drinks
Designed for replacing minerals without the carbohydrate load. Useful for low-carb eating, hot weather, illness recovery and general daily hydration where you do not want the sugar.

- Total sugar per serving
- What the sweetener is, if it is sugar-free
