Nuun branded products’ formulation is based on years of research and feedback from some of the world’s top academic and practicing experts in the field of sports medicine—specifically in dehydration and hyponatremia. Nuun's development is focused on the three most important aspects of proper hydration:


One of the most important characteristics of what you drink while you're active is the speed at which your body can absorb it. The concentration of dissolved salts and sugars (osmolarity, for those more technically inclined) determines how fast the drink can cross from your digestive track into your bloodstream, where it can re-hydrate and replenish you. Nuun branded products produce a hypotonic solution, so your body absorbs Nuun faster than the leading “sports drinks” or even water alone. This gives your body the ability to restore optimal water and electrolyte balance quickly and efficiently.


The American College of Sports Medicine recommends that people who are active for more than one hour get 500–700mg of sodium for every liter of water they consume. This is up to three times the sodium amount that traditional “sports drinks” provide. Some experts in the field believe that sodium concentrations should be closer to the 700–1000mg range. In addition to other critical electrolytes, Nuun Active Hydration provides 700mg of sodium for every liter of drink to ensure that you are adequately replenishing your body to help you perform at your best and stay healthy. U Natural Hydration is an all-natural line of electrolyte and vitamin-enhanced drink tablets with half the sodium as Nuun Active Hydration. U Natural Hydration is sweetened with stevia and contains only 7 calories per tab. It is ideal for less intense activities, a perfect way to stay balanced and quenched.


Nuun branded products contain virtually no carbohydrates (less than 1g) for a couple of reasons. Ingesting drinks containing high levels of carbohydrates can slow the rate at which your stomach empties, delaying the absorbance of the water and electrolytes. Carbs also increase the osmolality of what you're drinking, delaying absorption beyond the stomach.

If you're participating in intense exercises lasting more than 60 to 90 minutes, you should consume carbohydrates to ensure energy levels for working muscles. But how you do that is up to you. Everyone manages energy consumption differently, whether it’s with sports bars, gel or other sources of calories and carbohydrates.
