nuun (pronounced ‘noon’) was originally the brainchild of a student and professor from the tuck school, dartmouth college’s business program. new england was great for fall cycling, but the two became frustrated in their search for an electrolyte hydration solution to use in remote places. they longed for a lightweight, easily-dissolvable product that was free of carbohydrates.
Dissatisfied by pre-made and powdered options on the market, they set about developing their own solution. the answer came in the form of a simple tab that would come to be known as “nuun”.

Fast forward a couple years, past endless sample versions (including those that dissolved slower than granite) and nuun is pioneering portable electrolyte hydration for athletes and those with active lifestyles. just drop a nuun tab in your water bottle whether running, cycling, hiking, adventure racing, kayaking, golfing, or traveling, and store the tube in your jersey pocket or pack.

Nuun turns every water fountain into a source of optimal, balanced hydration.

nuun is a simple and easy to use solution but addresses a serious issue. we spent a lot of time getting the performance of the product right and ensuring the optimal balance. if you’d like to know more about what nuun is, and why, read this...

Formulation and nutrition

nuun’s formulation is based upon 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). development focused on the three most important aspects for proper hydration:

Speed of absorption

the most important characteristic of what you drink while you are 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 gut into your bloodstream where it can re-hydrate and replenish. nuun produces a hypotonic solution so that your body will absorb nuun faster than the leading “sports drinks” or even water alone. your body is therefore, able to restore optimal water and electrolyte balance more quickly.

Electrolyte content

the american college of sports medicine recommends that people who are active for more than one hour get 500–700mg of sodium for every litre of water they consume. this is up to three times the sodium that traditional “sports drinks” provide. in fact, some experts in the field believe that sodium concentrations should be closer to the 700–1000mg range. nuun provides 700mg of sodium for every litre of drink - this amount, in addition to the other critical electrolytes contained in every nuun tablet, ensures that you are adequately replenishing your body’s stores to help you perform at your best, and stay healthy.

Carbohydrate content

to ensure rapid absorption, nuun contains no carbohydrates. ingesting drinks containing high levels of carbohydrates can have two undesirable effects when it comes to hydration. carbohydrates can slow the rate at which your stomach empties and therefore delays the availability of the water and electrolytes. they also increase the osmolality of what you are drinking; delaying absorption beyond your stomach. please note: if you are participating in intense exercise for more than one hour you should also consume carbohydrates to ensure that you can sustain energy levels for working muscles. Carbohydrate loaded sports bars, or gels are effective means of providing you with the energy you require.
