Review: NUUN Hydration Tablets

Staying well hydrated no longer needs to be a tasteless chore. NUUN hydration tablets make your water more palatable while loading it with electrolytes — and all this with only six calories (read "no added sugar") per 16-ounce serving.

NUUN tablets dissolve in water, similar to Alka Seltzer, but NUUN tastes much better, and once the tablet has dissolved the bubbles disappear. The ratio is one tablet for 16 ounces of water, which just so happens to be the size of many cycling water bottles. The tablets come in five flavors: lemon-lime, tri-berry, orange ginger, kona cola, and citrus fruit, and all are made with no artificial colors. A sports drink doesn't need to be neon-colored to quench your thirst.

To see how I think NUUN tastes,


In general, I am not a big fan of sports drinks; they either taste too sugary or taste too much like artificial sweeteners. I like NUUN because it doesn't taste like either. The NUUN flavors are mild, which I like — especially when I am working hard. My favorite flavor is tri-berry, with citrus fruit in a close second. Unless you like sipping on flat Coke, I wouldn't bother with the kona cola, although I hear it blends nicely with the orange ginger. You can halve the tablets and become your own NUUN mixologist. NUUN is sweetened with sorbitol, a sugar alcohol, and acesulfame potassium, an FDA-approved artificial sweetener. I like that the drink is made in my reusable water bottle, so I don't feel like I am adding too much to landfills since the tube (but not the stopper) is recyclable. I also appreciate that this is an electrolyte drink fortified with the sodium, potassium, magnesium, and calcium I need to not become dehydrated, and that it is not a recovery drink with carbs, sugar, and protein. I like to eat these after I workout, not drink them. All in all, I am a fan of NUUN.

A single tube, with 12 tablets (makes 12 16-ounce drinks), retails at REI for $6.50. You can also buy the tubes in bulk — four tubes for $22 from REI, or packs of nine from the online NUUN store for just under $50.

If you're already a fan of NUUN, tell me why below.

I LOVE Nuun. I always use them on my long runs. Especially when it's hot outside. If I don't take them I feel the effects of lack of energy and salt and it affects me for hours after the run. But Nuun has the perfect electrolyte combo and are easy to just drop in my water and I can carry extra ones with me for the really long runs when I need to refill my bottles along the way. I can't use Gatorade because it doesn't have enough salt.

I use them for late summer (ie motherf-ing HOT) triathlons. I prefer to get my calories through Gu & solid (real) food during longer races. And since Gatorade & Gu DO NOT MIX WELL these treat my tummy well. No more barfing on the bike for me! This may have been an overshare. But I LOVE nuun!

I use these when I go for long bike rides and think they are great. The tube is actually close to the size in the photo lollofit, so it fits easily into little bag I keep under my seat for tools and patch kit.

haha- this picture is funny. There's nothing to give those tablets scale but the bottles, so they look GIGANTIC!... just for anyone who might take this comment too seriously, I realize that they're not.. :)

I love these - they're perfect for hydrating during and after hot yoga because they don't have all the sugar of gatorade. They contain potassium, too, which helps ward off the foot cramps I sometimes get when I'm sweating like crazy!

I got these because I was working outdoors during the summer in 100+ degree weather and hiking up and down a lot of slopes for work. I was thrilled at the prospect of not using bottles to be recycled of sport drinks. They tasted great but quite honestly the sorbitol left me gassy through the afternoon. My GI tract did not process the sorbitol very well. I bought lemon+lime and orange ginger and went through more than half of each container before I finally stopped.

I'll stick with water.

No thanks. I'd feel like I was drinking AlkaSeltzer recreationally, and that is pretty unappetizing.
