Nuun Zero Sugar Hydration Electrolyte Tablets Mixed Citrus 4‑Pack — 40 Servings, Gluten‑Free Vegan

Nuun Zero Sugar Hydration Mixed Citrus tablets are effervescent electrolyte servings that add essential sodium, potassium, chloride, calcium and magnesium to water with zero sugar.

Whether you want a flavorful way to drink more water between workouts, during long workdays, or on gentle activity days, these fizzy tablets turn plain water into a balanced hydration drink. Each tube contains 10 dissolvable tablets and the 4-pack includes two Orange Sunrise tubes and two Lemon Splash tubes for 40 single-serve portions. Formulated for everyday hydration needs, Nuun Zero Sugar is gluten-free, vegan and made from clean, non-GMO ingredients.

How do these tablets support everyday hydration?

Nuun Zero Sugar supplies five key electrolytes to help maintain fluid balance when you’re active or at rest. The combination replaces minerals you may lose through normal daily activity and helps your water feel more satisfying and refreshing.

• 200 mg sodium per tablet to support fluid retention and taste
• 125 mg potassium to help balance cellular fluids
• 75 mg chloride, 30 mg calcium and 20 mg magnesium for rounded electrolyte support
• Zero sugar so you can hydrate without added calories or sweetness

When should I use Nuun Zero Sugar instead of plain water or sports drinks?

Use these tablets when you want a light, electrolyte-enhanced beverage without calories or when activity is low to moderate—walking, yoga, commuting, or desk work. They’re not designed for heavy sweat sessions where higher carbohydrate or sodium intake may be preferable.

• Add one tablet to 16 fl oz (about 500 ml) of water for a single serving
• Ideal for hydration between workouts, travel, or throughout a busy day
• Choose other Nuun formulas for high-intensity or long-duration endurance events
• Mix-and-match tubes from the 4-pack to alternate flavors day-to-day

How do I use, store, and carry Nuun tablets for best results?

Using Nuun Zero Sugar is quick and portable—drop a tablet into water, let it dissolve, and sip. Tubes are designed to fit a gym bag, office drawer or travel kit, and unopened tubes have a long shelf life when kept dry.

• Drop one effervescent tablet into 16 fl oz of water and wait until fully dissolved
• Store in a cool, dry place; reseal tube after each use to protect remaining tablets
• Each tube holds 10 tablets; the 4-pack provides 40 servings total
• Carry a tube for on-the-go hydration—no refrigeration needed

What flavors are included and how strong is the taste?

The Mixed Citrus 4-pack contains two Orange Sunrise tubes and two Lemon Splash tubes, offering bright, light citrus notes that enhance water without overpowering it. Flavor is intentionally mild so it’s pleasant for multiple daily servings.

• Two tubes Orange Sunrise and two tubes Lemon Splash per 4-pack
• Delicate fruit flavoring keeps drinks refreshing and easy to sip
• Zero sugar and plant-based ingredients for clean taste profiles
• Adjust water volume to soften or intensify flavor as desired

Who is this for? Nuun Zero Sugar Mixed Citrus is suited to anyone who wants a convenient, low-calorie way to make water more appealing while replacing everyday electrolytes — commuters, office workers, casual exercisers, travelers, and those following vegan or gluten-free diets. If you need strong carbohydrate-fueled hydration for intense endurance sessions, consider Nuun’s sport-specific options, but for daily sip-and-go hydration, this Mixed Citrus 4-pack is an easy, portable choice.
