Nuun Sport and Skratch Labs Hydration Sport Drink Mix both add electrolytes to water, but they differ in format and carbohydrate content. Nuun comes as tablets; Skratch comes as a powder. The better fit depends on whether you want a low-sugar electrolyte drink or a mix that also provides carbohydrates.

The main difference: tablets or powder
Nuun Sport is an effervescent tablet you drop into water. Its low sugar and calorie count make it a straightforward option when you want electrolytes without much carbohydrate from your drink.
Skratch is a powder mixed into water. It provides more sodium than Nuun Sport and includes carbohydrates, so the drink can contribute some fuel as well as electrolytes. That can suit longer or harder workouts when you want carbohydrates in your bottle.
Which one should you choose?
Choose Nuun Sport if you prefer tablets, want less sugar and fewer calories, or want electrolytes without much carbohydrate.
Choose Skratch Hydration Sport Drink Mix if you prefer powder and want your hydration drink to provide carbohydrates during exercise.
There isn’t one best choice for everyone: Nuun emphasizes a convenient, lower-sugar tablet, while Skratch combines electrolytes with carbohydrates in a drink mix.
