    Perfect hydration product without the horrible sugar in Gatorade, etc.  Orange Citrus has a sort of chemical taste, I wouldn't pick this again.  Lemon-Lime is great.  Super easy to keep a tube in the gym bag, no mixing or powder hassle, and no big price premium for the convenience.

    Great light grape taste.  Small amount of fizz. Perfect during or after the workout!

    I've tried a few of the flavors, but grape is my absolute favorite! Now that I've used Nuun, I have a hard time with plain water on my runs.

    I use these to prevent dehydration or treat it at the first symptoms. I first started using them while cycle touring. I also use them when I have a dehydration headache coming on. The electrolytes + water helps more than just water alone. Often just water alone would not help me. These are easy to have on hand and mix up quickly. I discovered I do not like the Strawberry Lemonade, but I like Tri-berry, Lemon Lime, Fruit Punch and Banana. If you wanted to make these taste better you would add sugar and you can add nuun tablets to fruit juice etc. The reason people choose these instead of gatorade or others, though, is that you often specifically don't want the sugar.

    My doctor suggested that I try these, they tasted like swamp water with some drops of flavor.
    I asked my doctor if i could chew them and it was the weirdest experience of my life. They instantly started to foam up and fizz. I finally got a system to work when i really need electrolytes, but i could not do that everyday.

    I'm a big fan!  Served me well during my Ironman 70.3, and made me excited to drink fluids in the days before my event.  Mild flavor that not everyone will like, but I thought it was delicious!  Many electrolyte drinks are to sweet and leave me more thirsty than I was before drinking them; this quenched me.

    The convenience of the tabs is great. I just did not enjoy the taste. It has a weird "tinny" taste to me. Not sweet and a tiny bit fizzy. Just not for me.

    Feels too big

    I tried Kona Cola, I'm curious to try other flavors.  It made my mouth a lil dry.  On a really hot day of vigorous exercise, one would need more than NUUN.  The convenience factor is the best part, just put a tube in your gym bag to have on hand any time.  So nice.  It's good for every day stuff but I am looking into trying something more for when I do more than 1 sport in the same day.

    After testing out other hydration products, NUUN is absolutely the best!  It is the best tasting and does not have any sort of chalky aftertaste to it.  I LOVE this product and carry two flavors with me wherever I go.- Tri Berry and Kona Cola.  I use it after swimming, during aerobics, and any other activity I do.



Nuun (pronounced 'noon') was originally the brainchild of a student and professor from Dartmouth College's Tuck School business program in their search for an electrolyte hydration solution that was conveniently lightweight, easily-dissolvable and free of carbohydrates.

Dissatisfied by the pre-made and powdered options on the market, they set about developing their own solution. The Nuun tab they ultimately developed turns every water fountain into a source of optimal, balanced hydration.
