Nuun Sport is a dissolvable electrolyte tablet for active hydration, with five electrolytes and 1 g of sugar per serving.
For workouts, outdoor activity, and busy days, Nuun Sport offers a simple way to add electrolytes to water. Each tablet dissolves in a measured amount of water to make a flavored drink, so you can prepare a serving when you want hydration support at the gym, on a hike, or during your workday. The compact tubes are easy to keep with your activity gear or carry for use away from home.
Each serving contains five electrolytes: 300 mg sodium, 150 mg potassium, 25 mg magnesium, 13 mg calcium, and 40 mg chloride. These are the electrolytes included in the formula for replenishment during exercise and support for hydration and muscle function. Nuun's science-based electrolyte claim refers to the ratio of sodium, chloride, and potassium in its products.
Drop one tablet into 16 fl oz (473 mL) of water, then wait for it to fizz and dissolve before drinking. The single-tablet preparation gives you a straightforward way to mix an individual serving, whether you are preparing water before activity or keeping a tube nearby for later.
The pack contains four tubes of Nuun Sport tablets, with 10 tablets in each tube for 40 servings total. Each tube can be carried in a gym bag, car, or purse, making the tablets convenient to keep on hand for exercise, hiking, and everyday activity.
Nuun defines “clean” as non-GMO, vegan, and gluten-free, and the tablets are sweetened with stevia leaf extract. Nuun also brings more than a decade of experience in hydration science to its hydration products. The brand’s statements about hydration and muscle function have not been evaluated by the Food and Drug Administration.
Nuun Sport is suited to athletes, fitness enthusiasts, and active people who want a portable, dissolvable electrolyte drink for workouts, hikes, or everyday routines. Its defined serving method, five-electrolyte formula, and four individually portable tubes make it a practical fit for people who prefer to mix their drink with water as needed.
Active ingredients: Sodium (bicarbonate and carbonate), potassium (bicarbonate and chloride), magnesium (oxide), calcium (carbonate), Other ingredients: Citric acid, dextrose, natural flavors, stevia leaf extract, rice extract blend, avocado oil, beet juice powder (for color), riboflavin (for color), spirulina (for color), malic acid
