What the public facts say
- Each tablet is listed as a 5 g serving with 300 mg sodium, 150 mg potassium, 25 mg magnesium, and 40 mg chloride.
- The product page lists 15 calories, 4 g total carbohydrate, and 1 g sugar per tablet serving.
- Tablets include citric acid, dextrose, bicarbonate and carbonate salts, potassium chloride, magnesium oxide, calcium carbonate, stevia leaf extract, avocado oil, natural flavor, and flavor-dependent color or acid ingredients.
- The page lists several flavors, including Strawberry Lemonade, Lemon Lime, Tri-Berry, and Watermelon, with ingredient panels that vary by flavor.
Dietary notes
The reviewed official pages do not explicitly verify Vegan, Gluten-free, Vegetarian, or Dairy-free status for Nuun Sport, so no dietary tags are assigned. Nuun states that its tablet products do not contain tree nuts or peanuts and are made in a facility without those allergens; this is not equivalent to the allowed dietary tags.
A dietary tag is not an allergy-safety guarantee. Check the selected flavor’s current label and contact the manufacturer if needed.
Practical tradeoffs
Useful qualities
- Tablet format is compact and can be portioned into individual servings before mixing with water.
- Preparation is straightforward: the tablet is intended to dissolve in water and provides a measured electrolyte blend with relatively low calories and sugar per listed serving.
Things to consider
- The product must be mixed with water, so it is less immediately ready-to-drink than a bottled beverage.
- Flavor ingredient panels differ, and the official page directs shoppers to the package label for the most up-to-date information; range-level dietary assumptions are therefore limited.
These are format and ingredient observations from public sources, not tasting results or field-test claims.
Packing & preparation
The official page lists 10 servings per tube and shows a four-tube flavor bundle. Tablets are packaged as dry servings and require water for preparation.
