Nuun Vs. Pedialyte: Which Electrolyte Drink Mix Is Best?

Staying hydrated is crucial for our health and wellbeing. Proper hydration helps transport nutrients, remove waste, lubricate joints, and regulate body temperature. But when we sweat heavily from exercise, illness, or high heat and humidity, we lose electrolytes like sodium and potassium.

Drinking plain water cannot replace these lost electrolytes, which is why sports drinks and electrolyte solutions have become popular options.

Two of the most well-known electrolyte drink mix brands are Nuun and Pedialyte. But what’s the difference between them, and which one is better?

This comprehensive guide compares Nuun and Pedialyte drink mixes to help you decide which electrolyte product may work best for your hydration needs.

As you can see, there are quite a few differences between Nuun and Pedialyte when it comes to their ingredients, uses, flavors, and costs. Let’s explore these differences in more detail.

Key Differences Between Nuun And Pedialyte Electrolyte Drink Mix

  • Intended Uses
Nuun Hydration Mixed Juicebox Flavor Electrolyte Drink Tablets

Nuun is marketed for athletic performance and active lifestyles.

The tablets provide electrolytes to restore what’s lost in sweat without a lot of carbs or calories.

Nuun even has Immunity and Energy blends with extra vitamins or caffeine.

Pedialyte drink mixes are designed for dehydration relief when you have diarrhea, vomiting, fever, exercise losses, or hangovers. Pedialyte has more sodium and sugars to help absorb and retain fluids better than water alone can.

So while both can technically be used interchangeably, Nuun is better suited for everyday athletic hydration needs while Pedialyte is ideal for replacing fluids lost from illness or severe dehydration.

  • Format

Nuun comes in portable tubes of effervescent tablets that you drop into your water bottle. They fizz and dissolve to provide electrolytes and flavor. This allows you to customize your dosage and drinking experience.

Pedialyte only comes in powder form in single-use stick packs or resealable tubs. You tear and pour the powder into water and mix. The powders fully dissolve without fizzing. So Pedialyte offers less customization but more convenience if you want grab-and-go electrolyte drinks.

  • Electrolyte Content
Pedialyte Advanced Care Plus

Both Nuun and Pedialyte contain sodium and potassium, which are the two most critical electrolytes we lose in sweat and illness.

Nuun has 360-420mg sodium and 98-100mg potassium per tablet.

It also provides 25% DV magnesium and 13-15% DV calcium.

Pedialyte has 500-700mg sodium, 300-500mg potassium, 250-500mg chloride, and sometimes 10% DV zinc and magnesium. Pedialyte sticks to just the major electrolytes needed for rehydration.

So Pedialyte has higher levels of the biggest electrolytes lost – sodium and potassium. Nuun provides smaller amounts of additional electrolytes like magnesium and calcium.

  • Carbs and Sugars

Here’s a big difference between the two drink mixes. Nuun tablets contain 1g sugar and no carbs or calories beyond that.

Pedialyte powders have 9-10g of sugar per serving from added dextrose and sucrose along with about 45 calories. The carbs and sugars help absorption of sodium and water in the intestine when you’re dehydrated.

If you want an electrolyte boost without extra carbs or sweetness, Nuun is the better choice. Pedialyte’s sugars make it more palatable and effective for illness recovery.

  • Caffeine

Some Nuun products contain caffeine from green tea or coffeeberry extracts. Their Immunity, Energy, and Endurance blends have about 40-50mg caffeine per tablet. This makes Nuun a good electrolyte drink option for workouts.

Pedialyte does not contain any added caffeine. It aims to provide hydration support without stimulation for recovery.

  • Flavors
Nuun Hydration Mixed Juicebox Flavor Electrolyte Drink Tablets

Nuun comes in a wide variety of fruit flavors like lemon-lime, strawberry, fruit punch, cherry, and orange.

They also offer some unique flavors like tri-berry, citrus fruit, and tropical.

The fizziness provides added flavor.

Pedialyte sticks to just a handful of straightforward flavors like grape, lemon-lime, strawberry, and unflavored.

The powders mix to a thin, watery consistency without carbonation.

If you enjoy bolder, carbonated flavors, Nuun has a much wider range of options to choose from. For a neutral electrolyte drink, Pedialyte’s flavor selection gets the job done.

  • Cost

Nuun is a pricier electrolyte option. A tube of 10-20 tablets typically costs $6-12. Pedialyte powder packs are much more budget-friendly at $0.10-0.20 per serving if bought in bulk.

Nuun costs more upfront. But the tablets last longer than individual Pedialyte powder packs. So you may get more value from Nuun tablets in the long run. Still, Pedialyte is the cheaper choice per serving.
