Dry airplane cabins, hot destinations, long sightseeing days and the odd extra cocktail make it easy to get dehydrated while traveling. Nuun Sport electrolyte tablets are a light, TSA-friendly fix: drop one into a bottle of water and you have a low-sugar electrolyte drink in a couple of minutes.
What’s in Each Tablet (US Formula)
- Sodium: 300 mg
- Potassium: 150 mg
- Magnesium: 25 mg
- Calcium: 13 mg
- Calories: 15
- Sugar: 1 g
- Serving: 1 tablet in 16 fl oz (about 500 ml) of water
Nuun lists the product as vegan and gluten-free and sweetens it with stevia leaf extract plus a little dextrose. Always check the label on your package, because formulas can vary by region and flavor.
Why It’s Great for Travel
- Tiny and TSA-friendly: A tube of 10 tablets weighs almost nothing and isn’t a liquid, so it goes straight into your carry-on.
- Use any water: Fill up at an airport fountain after security and add a tablet.
- Low sugar: At 15 calories and 1 g of sugar, it’s much lighter than most sports drinks.
- Hot climates and hikes: The 300 mg of sodium helps replace what you lose through sweat on hot days.
Taste
Nuun Sport is lightly fizzy and comes in many flavors, including Lemon Lime, Strawberry Lemonade, Citrus Fruit and Fruit Punch. The taste is lighter than most sports drinks. Many people buy a variety pack to find their favorite.
