The American College of Sports Medicine recommends that people and athletes who are actively exercising for over one hour get 500–700mg of sodium for every liter of water they consume.
This is up to 3x the sodium amount that most sports drinks, which are high in calories and sugar.
NUUN tablets are a high absorbing electrolyte so you can more easily combat hyponatremia, a condition that is often mistaken as dehydration but is often a lack of salt that is sweated out during exercise and not replaced. Nuun provides 700mg of sodium for every liter of drink to ensure that you are adequately replenished.
NUUN tablets make an electrolyte drink with no sugar, only 3 calories and no carbohydrates

That's about a third of the caffeine found in your average cup of drip coffee.**
Nor is there any high fructose corn syrup. Even the very favorable Coconut water can have 12-18 grams of sugar. That’s not much compared with the sports drinks but a consideration for many. The no sugar makes these tablets ideal for athletes watching their weight and consumption as well as for those who have to watch sugar intake such as diabetics. NUUN Active Hydration Tablets contain electrolytes, vitamins and minerals and successfully ensures that athletes stay properly hydrated.
We liked the fact that you won’t replace the very calories you burn in one single “sports drink” which for some can defeat the purpose of exercise in the first place. There are no unnecessary additives unrelated to hydration with the exception of some light flavor. Athletes commented that they do not leave a residue in your water bottle.
NUUN Tablets are more portable—especially for athletes who travel
Tablets are stored in 4 x 1.25 in. plastic tubes that easily fit into a backpack or jacket pocket. That means you can stash them in a workout bag or a suitcase and add virtually no weight.
Subtle flavor and some of the flavors more popular than others
Do understand that this is a light flavor and tastes like flavored water. Citrus fruit, Orange and Tri Berry are the most popular flavors. Most love or hate the lemon lime and we simply did not get any feedback regarding the other flavors. Of course, this is subjective and these are sold in variety packs so you can mix it up and see which one you like best. You don't really taste the salts in these despite the lack of sugar.
Serving size and suggested intake of NUUN Tablets
Each tube has 12 servings. NUUN Tablets are often sold in four tubes per pack or 8 tubes per pack. You add one tablet to 16 ounces of water whether it’s your regular water bottle or a purchased bottle of water. You can add it to water that is cold, with ice or just room temperature.
