What Is Nuun?
Nuun is a hydration brand that makes dissolvable tablets and powders you add to water. Their products are geared toward athletes, runners, gym-goers, and anyone who wants a light electrolyte boost without heavy sugar or calories.
- Formats: Tablets and powders
- Calories: Very low (about 10–15 calories per serving)
- Sweeteners: Usually stevia or natural flavors
- Variants: Sport, Endurance, Immunity, Energy (some with caffeine)
Nuun is popular because it’s portable, convenient, and provides balanced electrolytes for everyday hydration or fitness.
What Is Pedialyte?
Pedialyte is an oral rehydration solution originally designed for children to help with dehydration from diarrhea, vomiting, or illness. Today, adults also use Pedialyte for rapid rehydration after workouts, travel, heat exposure, or even hangovers.
- Formats: Ready-to-drink bottles, powders, freezer pops
- Calories: Moderate (varies by formula)
- Electrolytes: High sodium and potassium for quick hydration
- Variants: Classic Pedialyte, Pedialyte AdvancedCare Plus, Pedialyte Sport
Because Pedialyte has higher electrolyte content than most sports drinks, it’s often considered “medical-grade” hydration.
