Nuun Sport is a watermelon-flavored electrolyte tablet drink mix designed to support hydration during exercise and everyday activity, with five electrolytes and 1 g of sugar per serving.
For workouts, hikes, and active days, Nuun Sport offers a simple way to add electrolytes to water. The tablets dissolve to make a watermelon-flavored drink, and their tube format is convenient to keep in a gym bag, car, or purse. Each serving provides a measured blend of electrolytes rather than a ready-to-drink beverage, so you can prepare it when you want a drink.
Each serving contains sodium, potassium, magnesium, calcium, and chloride to support hydration and muscle function. The amounts are 300 mg sodium, 150 mg potassium, 25 mg magnesium, 13 mg calcium, and 40 mg chloride. Nuun Sport is formulated to help replenish electrolytes lost through sweat during exercise.
Drop one tablet into 16 fl oz (473 mL) of water, let it fizz and dissolve, then drink. The tablet format lets you mix a serving in water when you need it, with watermelon flavor in each prepared drink. No special preparation beyond adding the tablet to water is described.
Nuun Sport is sweetened with stevia leaf extract and contains 1 g of sugar per serving. It is vegan, gluten-free, kosher, and non-GMO. Nuun defines “clean” as non-GMO, vegan, and gluten-free; this describes those attributes rather than a separate certification.
The portable tubes are suited to active routines such as gym sessions, hiking, and busy workdays. Keep a tube in a gym bag, car, or purse so a tablet is available to mix into water. The product is a drink mix for hydration support, not a ready-made drink.
Nuun Sport is suited to athletes, fitness enthusiasts, and active people who want a portable, watermelon-flavored way to add electrolytes to water. Its five-electrolyte formula, single-tablet preparation, and four compact tubes make it a practical fit for exercise and everyday activity.
Active ingredients: Sodium (bicarbonate and carbonate), potassium (bicarbonate and chloride), magnesium (oxide), calcium (carbonate), Other ingredients: Citric acid, dextrose, natural flavors, stevia leaf extract, avocado oil, beet juice powder (for color), riboflavin (for color), spirulina (for color), malic acid
