Who Nuun Is
Nuun is a Seattle-founded electrolyte tablet brand that's been a fixture of the endurance community since 2004. The brand was acquired by Nestlé Health Science in 2021 but has retained its product line and identity. Distribution in Australia covers endurance specialists, outdoor stores, and online.
The Range
Nuun's core product is the Nuun Sport effervescent tablet - drop one into 500 ml of water. The line spans Sport (the staple electrolyte tablet), Endurance (with added carbohydrate), Hydration Daily (lower sodium for everyday use), Rest (with magnesium and tart cherry), and Immunity (with added vitamin C and zinc). Flavour selection is broad - Lemon Lime, Tri-Berry, Watermelon, Strawberry Lemonade, Citrus Fruit, Orange, and others.
Formulation Notes
Nuun Sport tablets contain approximately 300 mg sodium, 150 mg potassium, 25 mg magnesium, and 13 mg calcium per tablet, along with about 1 g of carbohydrate. The line skews lower-carb than traditional sports drinks - it's designed to fit between water and a full sports drink, particularly for cyclists and runners during sessions where carb load is delivered separately.
