Nuun is a great product for keeping hydrated. It's an electrolyte replacement and hydration solution. It isn't like other sport drinks like Cytomax or Gatorade where you get carbs as well. Nuun has no carbs and solely focuses on the hydration/electrolyte issue.

It comes in small canisters of several tablets. Also many flavors to choose from which all seem good, though I prefer the tri-berry. You just drop a tablet into water and wait a minute or so for it to dissolve. This process makes it super easy to take on rides or runs.

My use: I usually head out on a ride with some Cytomax (for the calories) and a few tablets of Nuun. I have several rest stops where I can buy water or refill my bottles. At this time I drop a tablet in a bottle of water and drink it down. So the last half of my ride I usually have one cytomax mix and one bottle of Nuun mix. Similar with runs in that I take a tablet with me and refill my bottle at the water fountain in the park and drop the tablet in.

Pros: Easy to use, good light flavor, and great results.

The tablets make it very easy to carry extras. There isn't the mess or hassle of carrying powder.

Since there is little to no sugar/carbs in it, I can have the electrolyte balance correct and add as much carb as I want (I often mix it with carbopro). It also doesn't have the thick/sticky aftertaste or after feeling.

The stuff works great... I did a 100+ mile brick (about 95 mi on the bike and 6 on foot) in over 100 degree weather and had no cramping or dehydration issues.

Tri Berry and Citrus flavors are my favorites right now and will be with me at the next race!
