  • I’m trying to drink less so am having a Nuun rest and recovery tablet in water at night after dinner. With magnesium and cherry and electrolytes, I really feel like it helped to me relax and sleep better without the 3 AM anxious wake up. Tastes great and love that I can travel with it.

  • Nuun tablets are an easy way to stay hydrated. I like the daily hydration tablets since I tend to get dehydrated easily in warm weather, even when being inside most of the day. The flavors are not too salty or sweet, and the tablets dissolve well in water. The tablet tube is easy to carry around and fits in small bags for travel.

  • I originally bought these to use for the rare occasions when I needed electrolytes but they have transformed what I view as an electrolyte situation. Besides post-workout and hangovers I use them when I have a craving for pop by putting them into sparkling water, when I travel to help me stay hydrated and feeling healthy. I get the Juicebox Mix variety pack because I get bored of flavors easily but find them all good. Are they as good as a pop? No, but they're better than any of the other electrolyte tablets or powders I've used. They dissolve well into water and have helped me feel more hydrated and healthy.

  • Nuun is a great brand for electrolyte water additives on the go. I tried the tabs and found they were easy to use and store. I also found the flavors of the lemon-lime and the strawberry lemonade to be pleasant. The variety of flavors and options for how to use these make the item a top-quality electrolyte product.

  • I wanted to try these because they were fair in price and seemed like they could be a cool alternative to the more expensive hydration options. Unfortunately I'm not a fan of the carbonation taste in the drink. I can see how this is a good option for those that love carbonated beverages. Personally carbonation is fine with me most of the time, so I'm not sure why I don't like this. The ingredients list is clean at least.

  • Very yummy, and easy to mix in water when on the go! So much healthier than juice, but same lovely flavour with more benefits! Always carry at least one in my lunch bag and purse :)

  • I’m loving Nuun’s Daily Hydration Energy, especially the Tropical Punch flavor! It’s so easy to use just drop a tab into my 1L Evian bottle, and I’m set for the whole day at work. It gives me that extra boost of energy while keeping me hydrated throughout the day. it’s part of my daily routine especially since i'm doing Peleton everyday i need extra Hydratation. I picked mine up at Whole Foods - easy

  • I generally enjoyed using Nuus's products. I liked that they have different varieties to choose from that satisfies different needs; I also liked that they are also coming with some health benefits while making water tastes better.

  • I love most of the flavors of this brand Works well in my water bottle. I love that it keeps me hydrated and energized. Love the affordability of it too. It tastes great and mixes well. I like that you can buy tablet.

  • I enjoyed the strawberry lemonade flavour a lot, and am excited to try the others I ordered! Shipping was fast, easy and trackable.

    Feedback

    The price point seemed a bit high for the single serve sizes of some of their more powerful electrolyte hydration products.

  • Nuun is one of two of my favorite electrolyte supplements. I have three varieties on deck - vitamins, rest, and caffeine. As someone who likes less flavorful drinks, the tablet is a perfect option for me because I can simply break it in half to lessen any intense flavors (which do taste great, I’m just a Plain Jane :). I especially use Nuun to travel, since there are many servings in just one pack. Recently brought the rest and caffeinated on on a trip abroad. While it’s always difficult to stay hydrated while traveling, I just brought these tablets with me when I needed a little energy boost (40 mg of caffeine, so nothing overpowering or going to keep you up at night) or even when I was catching a red eye and wanted to hydrate and rest. It’s a top electrolyte brand for me, and I’m excited to try other flavors and Nuun products

  • Obsessed! I take two in my Nalgene every single morning before having any coffee and it’s truly the best way to start my day nice and hydrated! Especially living in Colorado…

  • The Nuun tablets helped me stay hydrated and helped me replenish my electrolytes.

  • My boyfriend reccomend I try these, they help me enjoy water and keep hydrated.

  • accessible intro to electrolytes as they are in little pill tablets that dissolve in water. I Prefer these to a mix as on the go it is difficult to make sure it gets fully integrated! Wish some of the flavors were a little less artificial tasting

  • Love this brand. I switch around favorites depending on the season but I feel so much better after drinking nuun that it has become a regular part of my day, every day. My latest preference is to brew some herbal tea and then add ice and a nuun, perfect balance.

  • Nuun makes great hydrating electrolytes. My doctor first told me about Nuun. They offer a lot of different flavors and have really clean ingredients. I have several packs on hand and take them with me to go as well. Perfect for an athlete, hang overs, hot days, or just anyone who needs hydrating. I’m a loyal customer and recommend them to anyone.

  • There are SO many rehydrating/electrolyte drink powders out there now, and this one honestly doesn't have the best flavor to me! I have tried several and this just isn't one of my favorites

  • Nuun electrolyte tablets are a great way to boost hydration, especially during workouts. They offer a variety of flavors and are low in sugar, making them a healthier alternative to sugary sports drinks. The tablets dissolve easily in water, creating a refreshing drink. However, the taste can be subtle, and some may not enjoy the slight aftertaste. Also, they can take a few minutes to fully dissolve, which may be inconvenient for some. Despite these small drawbacks, Nuun is a solid choice for convenient hydration.
