Expert Review - Nuun Active Hydration

On an endurance walk, you must replace salt lost with sweat. Nuun makes that replacement convenient. Add 1 tablet to each 8 oz. of water in your water bottle or the bladder of your hydration pack. It fizzes away to form a non-carbonated sports drink that provides salt and mineral replacement without sugars or carbohydrates or artificial sweeteners. It has a pleasant light lemon-lime flavor with no aftertaste.

For those watching their calories, Nuun provides great hydration and electrolyte replacement without calories.
