About Nuun

Nuun Tablets Review

Nuun’s vitamin and electrolyte-packed tablets help you tackle whatever is in front of you, whether that be a giant hill climb, a brutal cold, or getting a solid 8 hours of sleep. The brand’s tablets come in convenient, travel-friendly tubes to ensure you stay stocked up when you need to be.

The brand has been mentioned by athletes in publications like Forbes, Well+Good, Outside Magazine, The Cut, Mashable, Runner’s World, and many more.

This Nuun tablets review will take an extensive look at the brand and its bestsellers. We’ll cover customer reviews, promotions, FAQs, and more, to help you decide if its health and energy-boosting tablets can help you reach your goals.

Triathlete Tim Moxey created Nuun tablets to help himself train. He wanted something that was hydrating, easy to consume, and that didn’t include a ton of sugar or other unhealthy ingredients.

He soon realized that his product could help other people, too. So, Tim approached local shop owners and asked them to give his product a chance. We bet they’re glad they did because Nuun is now a globally known name. The company was officially founded in 2004.

But what makes Nuun’s product different from other electrolyte drinks? According to its website, Nuun was “the first company to separate electrolyte replacement from carbohydrates,” something that is highly desired by athletes and casual gym-goers alike.

Nuun has since branched out from tablets, adding pre-workout mixes and instant powders to its line of hydration-enhancing products. Based out of Seattle, Washington, Nuun continues to create new ways to improve your workout and overall well-being.

Does Nuun Help Weight Loss?

Nuun Tablets Review

Nuun hydration tablets don’t directly help with weight loss, but they do tackle two key factors that sometimes result in weight gain. These factors include your drink choices and dehydration. Choosing sugary drinks in place of water or other low-calorie beverages can result in putting on a few extra pounds a year.

Popular soda choices contain over 30 grams of sugar—that’s about 6 teaspoons worth. Well-known sports drinks aren’t any better. They contain the same amount of sugar, if not more than sodas do because you’re consuming double the volume. 

The Nuun Sports tablets are only 15 calories each and have just 1 gram of sugar. If you replace your regular sports drink with Nuun, you may find that you lose weight over time.

It’s also common for us to think we’re hungry when actually we’re just thirsty. The brain will have us craving chips and salty snacks when it really needs electrolytes. Nuun tablets contain those electrolytes to help you stay hydrated and eliminate signal mix up. 

As you can imagine, swapping up a 240-calorie bag of chips for a delicious 15-calorie Nuun drink will have quite an impact on your waistline.

Can You Drink Nuun Every Day?

Nuun Tablets Review

We’re all built differently. We have different nutritional needs and some of us require more than others. For example, a 6-foot male bodybuilder can eat upwards of 3k calories per day, but a sedentary 5-foot female only needs about half that amount.

With that being said, you can drink Nuun electrolyte tablets every day, but the amount you drink will vary based on your nutritional needs. Some find that 3-4 tablets of Nuun work perfectly for them, while others require less. If you’re on the go and constantly sweating, then you may find you need to consume more due to electrolyte loss.

Nuun is a hydration solution for those on the go. It’s filled with electrolytes, vitamins, and lip-smacking flavor. In the next section, we’ll focus on Nuun Sport, Immunity, Vitamins, Rest, Energy, and Endurance tablets, as well as apparel and drinkware.

Who Is Nuun For?

Nuun Tablets Review

Nuun is designed for a wide range of individuals who engage in physical activities and are looking for a convenient way to replenish electrolytes and stay hydrated. Here are some groups of people who may benefit from using Nuun:

  1. Athletes and Active Individuals: Nuun is popular among athletes, fitness enthusiasts, and those who engage in regular physical exercise. During workouts or vigorous activities, the body loses electrolytes through sweat, and Nuun can help replace those essential minerals to maintain proper hydration and electrolyte balance.
  2. Outdoor Enthusiasts: People who enjoy outdoor activities such as hiking, biking, camping, or running can benefit from Nuun. It provides a portable and easy-to-use solution to stay hydrated when access to water sources may be limited.
  3. Endurance Athletes: Nuun is commonly used by endurance athletes participating in long-distance running, cycling, triathlons, or other endurance events. These activities often involve prolonged exertion and sweat loss, making electrolyte replacement crucial for performance and recovery.
  4. Individuals in Hot or Humid Environments: People living or working in hot and humid climates may experience increased sweating and higher electrolyte loss. Nuun can help replenish electrolytes and maintain hydration levels in these conditions.
  5. Travelers: Traveling, especially to destinations with different climates or altitudes, can disrupt the body’s hydration balance. Nuun tablets can be a convenient option to support hydration during travel and prevent dehydration.

Nuun Reviews: What Do Customers Think?

Nuun Tablets Review

We’ve heard a ton of buzz about Nuun products, seen them in stores, and read about them online. Maybe you have too, but this wouldn’t be a thorough Nuun tablets review without the voices of real customers.

With that in mind, we turned to the internet to find out what users have said about the brand and its products as of June 2023.

We hit up the company’s website first to get a general feel for how Nuun’s products are received by customers. Each of its top-selling products has been reviewed hundreds of times, with average ratings of 4.5/5 stars or higher:

  • Endurance Citrus Mango Sachets are rated 5/5 stars by 248 shoppers
  • Energy Berry Blast is rated 5/5 stars by 394 shoppers
  • Rest Blackberry Vanilla is rated 4.5/5 stars by 414 shoppers
  • Vitamins Blackberry Citrus + Caffeine is rated 5/5 stars by 391 shoppers
  • Sport Cherry Limeade + Caffeine is rated 5/5 stars by 923 shoppers

Taking a closer look at the Sport Cherry Limeade + Caffeine tablets, we discovered an abundance of happy customers that love them for their superior hydrating qualities. One long-time customer reports that these tablets are better than others on the market:

Nuun has been my go-to hydration product of choice for YEARS. I’ve tried many of the others, and keep coming back. It’s great to know that the quality has remained the same over the years and customers trust them to deliver results.

One of the main issues that customers have with the Cherry Limeade + Caffeine tablets is their texture and taste. One reviewer wrote, “Didn’t work. Nasty. Made me feel sluggish.” The taste of Sorbitol may not be appealing to some that like regular sugar and excess electrolytes can have a relaxing effect on muscles.

Still, Nuun tablets are widely used by those in the Running and Keto communities on Reddit. One Redditor has been using them to push their training further:

I love the Nuun tablets. The strawberry lemonade is my favorite. I’m 3 weeks in and did my first mountain bike ride since starting back. I was concerned I would bonk out. I took some Nuun and some mixed nuts with me and felt great!

Nuun Tablets Review

Many commenters echo this sentiment—the Cherry Limeade + Caffeine flavor appears to be most people’s favorite!

In a Nuun Tablets review on Fueled by LOLz (fueledbylolz.com), the reviewer discusses the pros and cons. On the Rest tablets, she resorts that “you do get more restful sleep. Maybe you fall into a deeper sleep or wake up less.” She also appreciates their variety specifically for runners and athletes.

Although they mention more pros than cons, two issues the reviewer notes are the packaging and cost. At $7 per tube, that makes each tablet under $1—a pretty good price when compared to comparably sized sports drinks. As for the packaging, we hope the brand switches to something more eco-friendly in the future.

Overall, customers love the dose of nutrition and energy that the brand’s products give. We found mostly positive Nuun Tablets reviews, with many citing that the Sport tablets are a must-have for a long run or bike ride. 

Runners especially appreciate the small size of the tablets, which means they can quickly toss them in a glass during a marathon rather than lugging around a full sports drink.

Is Nuun Worth It?

Nuun Tablets Review

So, are Nuun tablets worth it? Let’s start with the cost. At less than $1 per tablet, Nuun creates an inexpensive alternative to sugar-laden sports drinks. They contain the electrolytes needed to replenish your body during hard physical activity. 

For those reasons alone, the verdict of this Nuun Tablets review is that they are worth the buy, but there are several other reasons we think you should check them out.

The brand not only offers tablets designed for sports, but ones to help you rest and boost your immunity. They do not contain anything artificial and are flavored and colored naturally.

The brand itself offers discounts and free shipping, along with a Satisfaction Guarantee that makes the risk of trying their products really low. We’ve read about great customer service and the ease of returns, so if you truly aren’t happy with your product the process of getting your money back is easy. 

So, if you’re looking to cut out sugary sports drinks and switch to a healthier, more natural, and cheaper alternative, we think Nuun is definitely worth checking out.
