How do we vet brands and products? Learn more.

While the best way to provide your body with electrolytes is to drink a lot of water and eat a balanced diet, you can also use electrolyte supplements. That’s where products like Nuun Hydration tablets come into place.

The manufacturers of this product claim that these tablets contain natural, non-GMO ingredients, including multiple electrolytes. It’s also said that they hydrate better than water and can help you improve your exercise performance.

After reading these claims, I decided to examine this product thoroughly. So, in this review, I’ll provide you with an in-depth examination of the ingredients that Nuun Hydration contains and share its benefits and potential side effects.

Nuun Hydration is one of the best hydration supplements out there designed to fuel your body with electrolytes. It comes in the form of tablets and powder that you can add to fresh water before drinking in order to support electrolyte balance in your body.

At first glance, what I noticed about this product is that it’s non-GMO, vegan-friendly, and gluten-free, which means people with celiac disease and those following a green diet can use it. Whether you sweat a lot, perform regular exercise, or even participate in long-distance runs, Nuun Hydration can definitely be helpful.

According to the official website, the main electrolytes that Nuun Hydration contains include sodium, potassium, magnesium, and calcium. In my opinion, the inclusion of these nutrients is great because they’re scientifically proven to have positive effects on your body.

Another important thing that I liked about these supplements is that they don’t contain any artificial sweeteners. Additionally, each tablet comes with just 1g of sugar per 16fl oz, which is lower than many electrolyte supplements out there.

Key Ingredients of Nuun Hydration Tablets

I like it when companies use natural ingredients to make nutritional products because it reduces the risk of side effects. Nuun Hydration supplements are no different. Plus, they’re vegan-friendly and gluten-free, making them a safe option for a variety of diets.

Let me explain the main ingredients these electrolyte replenishing tablets contain.

#1 Minerals

I would like to start by discussing the electrolytes Nuun Hydration comes with because they’re the main reason why you would want to use this product.

Here’s a list of all the minerals that the supplement offers.

  • Sodium carbonate/bicarbonate: It helps your body stabilize its pH levels, which can improve your exercise (or any other muscular endurance activities) performance.
  • Potassium bicarbonate: This mineral is also beneficial for your body, as it reduces calcium loss in your body to improve bone density and strength. Additionally, it can also enhance your cardiovascular health and regulate blood pressure.
  • Potassium chloride: Potassium is essential for your body to perform several important functions, such as regulating nerve transmission, performing muscle contraction, boosting heart health, and improving proper kidney function.
  • Magnesium oxide: This mineral is also essential for your body. It can help your body by improving blood sugar levels, reducing blood pressure, enhancing bowel movements, and decreasing the intensity of stress and anxiety.
  • Calcium carbonate: Consuming this mineral provides your body with calcium, which can lead to a healthy heart, nervous system, muscles, and bones, according to research. Additionally, it can also minimize the symptoms of upset stomach, acid indigestion, and heartburn.

#2 Avocado oil

Another important ingredient in Nuun hydration tablets is avocado oil. It contains lots of unsaturated fats, and research shows they can decrease your body’s cholesterol levels.

As a medical professional, I can tell you that the less low-density lipoprotein you have, the more likely you won’t get heart disease.

Studies have shown that unsaturated fats can improve your natural brain functions as well. Additionally, they can also remove free radicals that might cause oxidative stress.

When you have healthy brain cells, you can function properly during exercise and experience fewer episodes of anxiety and depression.

#3 Beet powder color

I’ve tested many dietary supplements that contain artificial flavors and coloring. But fortunately, that’s not the case with Nuun Hydration supplements. They come with beet powder color, which is a natural ingredient and makes for a rich source of iron, calcium, and potassium.

Your body needs these important nutrients to maintain strength and relieve any muscle cramps after exercise. According to research, this powder can improve athletic performance in people who consume more nitrates.

Getting more nitrates in your diet can improve blood flow, oxygen uptake, and overall endurance. This means you have a reduced risk of developing heart disease in the future.

However, I must mention that too many nitrates can lead to serious constipation and fatigue. So, make sure you consume them in moderation.

#4 Citric acid

Citric acid is the compound naturally present in citrus fruits. This is what gives lemon and limes a sour taste, making it a perfect option for the bitter Nuun supplement flavors.

Studies show that this organic compound contributes to a strong metabolism and nutrient absorption. When you have a fast metabolism, you’ll be able to burn more calories. It means that citric acid consumption can also help you support your weight loss journey indirectly.

#5 Stevia leaf extract

I also liked the inclusion of stevia leaf extract in this product because it’s an excellent way to enhance the flavor without using sugar. It’s a natural ingredient that can help you lower blood glucose levels in combination with regular exercise routines.

Here, I must mention that regular consumption of stevia can cause negative effects in some people. While it’s generally considered safe, it can lead you to consume more calories throughout the day, which can increase your weight.

#6 Dextrose

Dextrose is a type of sugar similar to the one present in your blood, and it’s obtained from different natural foods, such as honey, fruits, and corn. Although it’s a natural ingredient, it can lead to increased weight if consumed in excess.

But what I liked about Nuun supplements is that each serving contains only 1–2 grams of this ingredient, which is safe and won’t cause weight gain.

Expert’s Comment

The Nuun Sport tablets contain magnesium, potassium, calcium, and sodium – important electrolytes that support your health much better than many sports drinks. These tablets are mixed with water before consumption, which can prevent serious dehydration from an intense workout and can also help you lose weight.

The amount of sugar a supplement contains is an important factor to consider because it can lead to weight gain. Nuun products come with low sugar content compared to other sports drinks and have natural ingredients, such as beet powder color and stevia leaf extract.

It makes Nuun supplements a safer and better option to support your exercise routine. However, it’s important to remember that this product contains a lot of sodium, and excess consumption of this mineral can have negative impacts on your body. So, you’ll need to be mindful of your daily sodium intake.

Lastly, make sure that you talk to your doctor before adding any type of dietary supplement to your diet. They’ll review your current medical condition and advise you accordingly to make the right decision.

Nuun Hydration Benefits

Fluid loss and decreased electrolytes in your body can cause many side effects, including a dry mouth, increased thirst, severe fatigue, and migraines. Nuun Hydration can help you prevent these symptoms because of the benefits it offers.

In this section, I’ll explain all the benefits you can reap using this product.

#1 Supports hydration

Nuun hydration supplements are specifically designed to help you replenish your electrolytes and stay hydrated, especially during and after exercise.

Your body needs plenty of fluids to function properly and maintain energy levels. Becoming dehydrated can have long-term side effects that affect your overall health.

I agree that drinking plenty of plain water can keep you hydrated and can even offer some electrolytes, but not everyone enjoys it. Additionally, it’s not as rich in nutrients as specially designed supplements.

So, adding flavored tablets to plain water can be a better option to improve your experience and boost hydration without it feeling like a chore.

#2 Promotes electrolyte replenishment

A single serving of the Nuun supplement provides your body with multiple electrolytes, including sodium, magnesium, potassium, and calcium. In my opinion, these are the best ingredients in this product because they help you prevent feeling exhausted and keep functioning properly.

Not everyone realizes that fluid balance is very important for your health. It helps regulate chemical reactions and maintain fluids in and outside of cells. Most of the time, you’ll naturally find this balance when eating food and drinks that contain electrolytes and vitamins.

#3 Can boost energy levels

Mineral and active ingredients in Nuun supplements can boost your energy levels and improve your physical performance. For instance, avocado oil retains lots of antioxidants – compounds that feed the body more energy and keep it free of harmful toxins.

So, it goes without saying that the more energy you have, the more likely you’ll lose weight and avoid muscle cramps.

#4 Natural ingredients

I try to steer clear of dietary products that contain heavily processed and artificial ingredients because they can affect your overall health negatively.

There are many sports drinks out there that contain such ingredients, along with high amounts of sugar and sweeteners. Not only do they lead to side effects, but they can also make you gain weight.

But Nuun Hydration tablets come with natural and clean ingredients and don’t contain anything artificial. It’s one of the major reasons why I liked the formulation of this product.

Nuun Hydration Cons and Side Effects

Just like any other product, Nuun Hydration also comes with some side effects and downsides. Let me explain them in detail to help you decide if it’s the right choice for you.

#1 Too much sodium 

Although sodium is an important electrolyte your body needs, too much of it can be unpleasant. Large amounts of this mineral might increase the risk of heart disease, high blood pressure, and kidney disease. This is why you need to carefully monitor how many tablets you have each day.

According to the official website, each Nuun tablet contains 300mg sodium. As a medical professional, I can tell you that the ideal amount of sodium in a single day is 1,500mg. So, if you decide to consume 3 of these tablets throughout the day, which is what the company allows, you’ll be getting 900mg of sodium from this supplement.

Additionally, if you consume sodium from other food sources, which is certainly possible, you can exceed the daily recommended safe threshold.

Important note: People who currently have long-term heart problems should avoid this supplement unless their doctor says it’s safe. The same goes for hypertension conditions and pregnant women. Always get advice from a medical professional before you take new dietary supplements.

#2 Possible caffeine overdose

There are three different flavors under the Nuun Sport category that contain 40mg of caffeine in each dose. If you consume three of these tablets every day, you’ll be getting 120mg of caffeine from this supplement, which is safe.

However, if you’re also a coffee lover and drink it multiple times a day, you can exceed the generally recognized safe caffeine limit, which is 400mg.

So, I believe that Nuun caffeine flavors can be problematic for coffee lovers. That’s because too much consumption of this nutrient can lead to headaches, fast heart rate, dehydration, anxiety, and shakiness.

Nuun Online Customer Reviews

I make it a habit to read online reviews of any product I’m testing and reviewing. This allows me to find out what real users have to say about the product so that I can set my expectations realistically.

I did the same with Nuun Hydration, and here’s what I found.

Magan is also a satisfied user as she shares similar thoughts to Laura. The simple formula and ease of use of this product make it a great option for staying hydrated.

While Veena is also satisfied with the supplements, she says that their price is on the higher side. Although a single serving costs you $0.70, which is lower than many similar products I’ve tested and reviewed, the price could be lower as it’s still just a hydrating supplement.

If you consume just 3 tablets a day, you’ll be paying more than $2 daily, which many people might not be able to afford.

Nuun Hydration Cost

Nuun Hydration supplements are available in the form of tablets and powders, and at the time of writing, these are the prices:

  • Single tube containing 10 tablets: $7.49 ($0.70 per tablet)
  • Powder bag with 16 servings: $23.99 ($1.49 per serving)

The company also offers a monthly subscription payment model that you can use to save 15% of the amount.

FAQs

Is it good or bad to use Nuun Hydration tablets?

There’s nothing wrong with using Nuun Hydration supplements. They are great for maintaining hydration, boosting your energy levels, and regulating electrolyte balances. It might be bad to take more than 6 tablets in one day, depending on how much you exercise and sweat.

Is it okay to drink Nuun Hydration every day?

You can definitely drink these dissolved supplements every day. Most people regularly visit the gym or go for long runs, so an energy-boosting beverage is needed to maintain strength. However, you don’t need this every day if you’re resting and not getting much exercise.

Can Nuun tablets cause diarrhea?

Any hydrating supplement, including Nuun, that contains sodium can cause diarrhea. But it happens only if you consume more sodium than the recommended daily allowance. If you’re mindful and consume hydrating supplements in moderation, you should not experience this problem.

How many Nuun Hydration tablets should you take per day?

The company recommends not to take more than 3 tablets in a single day. However, the number of Nuun tablets you should take daily depends on your unique needs. For example, if you follow a light workout routine, a single tablet would suffice.

How I Tested Nuun Hydration

The most important factors I consider while testing a product include quality, effectiveness, price, and brand reputation. Read on to find out how I evaluated Nuun Hydration in terms of these factors.

Quality 9/10

When it comes to quality, there’s not much to complain about Nuun. It’s a high-quality product that contains natural ingredients, which are safe for people following a vegan-friendly or gluten-friendly diet. Additionally, it’s also a non-GMO product certified by the non-GMO project and doesn’t contain any genetically modified nutrients.

Effectiveness 8/10

Nuun supplements are also effective in doing what they’re supposed to do, which is replenish electrolytes and keep you hydrated. My only reservation about the effectiveness of these products is that they can cause some side effects due to the high amounts of sodium and caffeine, but only if you’re not careful.

Price 8/10

While Nuun hydration is not very expensive compared to other similar products, the price could still be lower. That’s because a single tablet costs you $0.70, and if you consume three of them daily, you’ll be paying over $2 every day. This is not the kind of money that many people would like to spend on a hydrating supplement.

Brand reputation 9/10

Nuun was founded back in 2004, and it has been serving the community with its hydrating supplements since then. According to the official website, it’s the company that pioneered the separation of electrolyte replacement from carbohydrates.

It has a large and loyal customer base because of its effective hydrating products with natural ingredients. All these factors have allowed Nuun to position itself as a well-reputed and trusted company in the hydration supplement industry.

Nuun Hydration: The Final Verdict

In conclusion, I would say that Nuun Hydration is an excellent option for people looking for a convenient way to replenish their electrolytes. It comes with natural and clean ingredients that can help you improve your exercise performance while staying hydrated.

You just need to keep in mind that the product contains a lot of sodium. This means that if you consume this mineral from other sources, your intake may exceed the recommended daily amount of sodium. The same is true for caffeine if you drink coffee every day and also add caffeinated Nuun flavors to your diet.

Lastly, I would remind you again that it’s not the only hydrating supplement available in the market. There are many other options out there that you can use if you’re concerned about Nuun for any reason.
