As tasty as Nuun's Electrolyte Tablets are, it's always nice to be able to mix it up (pun intended). By that, we mean that we like to have a few flavors on hand to feel like we're sampling from a mixed species orchard. This Nuun Electrolyte Tablets Original Flavor Mixed 4 Pack contains their original four flavors -- and some of our favorites.

Nuun's Electrolyte Tablets are designed to dissolve completely in one 16oz. bottle of water. This ratio gives an optimum hypotonic solution that's readily absorbed across the cell membrane to fight dehydration, but contains enough salts to restore and/or maintain the electrical function within the cells to combat hyponatremia. This is important for muscle cells, nerve cells, and red blood cells alike as they all perform vital functions when you exercise. Pure water is better than none at all, but without including salts as Nuun Tablets do, you can essentially leach the nutrients from the cells, impairing function. So for maximum performance, you must be properly hydrated, and Nuun's 700mg per liter sodium mix is exactly what you need when you're working hard.

Nuun Electrolyte Tablets Original Flavor Mixed 4 Pack includes 4 tubes of 12 tablets each. There are four fruity flavors -- Lemon-Lime, Tri-Berry, Citrus Fruit, and Orange. One serving consists of one tablet dissolved in 16oz of water. There are less than 8 calories per serving as Nuun is formulated strictly for replacing the salts your body loses through sweating. Each serving contains 360mg of sodium, 100mg of Potassium, 12.5mg of calcium, and 25mg of magnesium. You'll also get 37.5mg of vitamin C and 500mcg of vitamin B2.

Must have for any trip.

First purchased this product for a 50 mile trek through the bottom of the Grand Canyon. Liked the product for the compact size, and flavors available. And will continue to buy. Sometimes I will use half of the recommended tablet to water ratio with no real side effects with the exception of a weaker flavor. No real issue IMO. Purchased another 8 tubes and haven't ran across a flavor that I didn't care much for.

Great for Long and Short Rides Alike

  • Familiarity: I've put it through the wringer

I have been using the nuun for a few years now, and would not cycle without them. It adds a great (light) effervescence to plain water and flavor as well. Can I say definitively that it has helped me absorb the water/hydrate better? No, I am not a freakin' scientist, but I mentally believe it does - which in cycling, mental is half the battle. Very light flavor, awesome on long rides. I use them in up to 20oz bottles no problem.

Not for me

I tried these hoping for a great tasting add-in to liven things up on the trail. I didn't like them at all. They sort of carbonated my drink, kinda like alka selzer. The flavoring was very weak. I went back to my standard propel packets. Not as healthy I guess, but the flavor is way stronger, and gives me that extra punch that water sometimes doesnt give alone. I know some love it, but it is not for me.

So Good

This tastes really good and I prefer it over many other kinds of drinks. It is a great hydrator, and I use it on most of my trips. I highly recommend it

Cheap, tasty, and useful.

These things are great. They keep you hydrated, add some flavor to your water, and they are super portable. Drop one in a water bottle, or 2 in a hydration pack, and you are good to go. Just don't drop the nuun and seal your drinking vessel right away, as it fizzes pretty strongly. Also, if you are into hydrating yourself as you dehydrate yourself, the lemon/lime flavor mixes pretty well in a ghetto G&T for post-activity celebration.

Not too sweet or messy - just right

If you've never used these before, they take a bit of getting used to as they are not like your ordinary powder mix. Instead, they are tablets roughly the size of a quarter (half dollar?) which you plop into water and they then dissolve by fizzing. Depending on how strong you mix it, Nuun creates a very light flavored sports drink which is very palatable for long distance events, like a full day of backcountry skiing.

As an added bonus, they come in a small plastic tube, which if perfect for travel and/or storage. Unlike a bag or tin of sticky powder, the Nuun packages won't spill all over everything and gunk up your junk.

I'll often use just half a tablet, which is easy to do as they come pre-scored for easy breaking in two.

They got a 4 instead of a 5 due to being so pricey.

All 8 mixed fruit favors are excellent!

  • Gender: Male
  • Familiarity: I've put it through the wringer

Water is okay and all, but Nuun is so tasty that I am more motivated to keep drinking and stay hydrated. It does not create a build-up in my water blatter. All 8 of the mixed fruit favors are excellent!

Encouraging taste

As a person who does a lot of high output activity I find myself in constant need of hydration but after a while water alone gets boring and uninspiring. That is where these come in. I actually like them really diluted so I just pop 1 or 2 into my 64oz hydration bladder and call it good. It is just enough of a taste to encourage me without being overpowering. I will also drink a concentrated beverage at the beginning of the day to preload my h2o needs and be sure to have some electrolytes on board.

Terrible flavor discourages water consumption

I bought the mixed flavor pack because some flavors aren't as good as others. However, to my surprise, they were all terrible. The recommended dosage tastes extremely watered down, but adding more does not really improve the disgusting fizzy taste.

It may be full of all sorts of essential vitamins and electrolytes, but I actually dreaded drinking the water. This is completely counter productive to the purpose.

It wasn't just me. My entire backpacking group of 5 agreed.

Chris- so sorry you had a bad experience! Our best selling flavors are Strawberry Lemonade and Fruit Punch. I don't know which 4-pack you chose but this might help out the flavor selection. Also, if you aren't a fan of the fizzy-ness, you can mix it in advance and leave the top off. The effervescent does eventually come out of the water and the fizzy sensation goes away. Happy Hydrading! ~Your Nuun Representative

Not What I Thought

What is Sorbitol?? Fake sugar stuffs, gross. I was really excited about this product because it was advertised as you can see as sugar free. Well that is not really true, it has artificial sweetener in it!!! I wish there was a hydration product out there that didn't have anything but the goods and no crap in it. Also it kiind of bothered my stomach which is common I guess with Sorbitol.

Responded on

mco5291890- Just hoping to help out here! Sorbitol is a naturally occurring sweetener. Each tablet contains the same amount you would get in about 8 oz. of Apple Juice. Drinking Sorbitol in mass can upset the stomach but it was more likely the effervescent that bothered you. I would recommend letting it sit out for a while before consuming it and trying again.
Also, Nuun just released a product that uses Stevia as the sweetener. If the artificial sweetener turns you off, this is a great option. Some of the flavors are sweeter and stronger than others so getting the mixed 4-pack of that product might be the way to try it out! Happy Hydrating! ~Your Nuun Representative

These are a staple in my nutrition plan for training & competing in ultramarathons. The flavors are slight enough to be able to tolerate for hours and you still get enough electrolytes to legitimately stave off muscle cramping. With 360mg Sodium & 100mg Potassium, they replace the need to take oral salt tabs which can be difficult to eat while running. Love the grape flavor these days, but they have a bunch of flavors that are awesome. I love nuun.

4-pack Trial

I love this 4-pack option. It lets you try the flavors without committing to an entire 8-pack. I can drink this stuff while I am working out or sitting at my desk. Plus, at about $.50/serving it less than a diet coke (and much healthier)!

All great flavors, from their original to their new line of flavors

If you want energy with a hint of flavor that isn't too overpowering or chalky, then this is your choice. It helps with lactic acid build up and holds true to being a quick energy booster when you need it most.

A great product in any avenue, from a hard competition to a nice walk in the park!

Great New NUUN Flavors

I've been trying out the Fruit Punch/ Tropical/ Grape/ Strawberry Lemonade mixed fruit Nuun 4-pack and really like the new flavors. My personal favorite out of this 4-pack is the Strawberry Lemonade, followed closely by Tropical. I like the Grape and Fruit Punch too - really, it just comes down to personal preference. If you're not sure which flavor(s) are for you, these 4-packs are a great way to try them out and see what you like best.

They're Good!

These work great to keep me going when I need electrolytes. I don't really like gatorade, but when you need electrolytes, you need them! These work great for flavoring water also after you purify them, or if you can get water out on the trail but it tastes slightly off. Best of all, these don't upset my stomach after a long day like some other hydration drinks do.

Big fan

I am not a huge fan of straight up water so these are great for me. I use them on hikes or sometimes when I am at my desk and I can take down any more plain water. The taste is not super strong which is good because I don't want the more syrupy gatorade-like taste. Also, you don't get as strong of the salty electrolytey taste as do with other sport-type drinks. I personally like the orange and the citrus flavors the best (hard to screw up citrus). The other flavors are not bad by any means.

Jonathan, you may also want to try the U by Nuun product for all day use. I like it because the flavors are more like tea than a sports drink. The flavor is still mild and it still contains electrolytes but it also contains vitamins.

Wanted to love these for their uber-convenience

Wanted to love these for their uber-convenience while backpacking and for the reasons every other reviewer seems to love them, but I just didn't. Something about the taste didn't sit right with me, and unfortunately it was the only thing I brought along, so I drank water for the whole backpacking trip, and my buddies didn't want them either. I'll give it four stars, as is seems to do what it's supposed to do, I just didn't care for the taste.

Responded on

Big Papa, which flavor did you try? I am curious because there are some flavors I love (citrus fruit, strawberry lemonade) and some flavors I would rather not drink if I had another option. There are 11 flavors now, 5 new flavors came out in April, and out of the new flavors, some are super sweet (fruit punch, grape) and others are more mild in flavor (Lemon Tea, Strawberry Lemonade). This stuff is uber-convenient so I would suggest a new flavor before you give up completely! It is great stuff for travel and trail.
