General FAQs

What is Nuun?

Nuun is a portable sports drink mix that contains the necessary electrolytes to keep you properly hydrated without all the sugars like most sports drinks.  It’s used by cyclists, triathletes, runners, hikers, yoga bods, just about anyone who’s active and wants to stay properly hydrated. Drop a Nuun in a bottle of water and you’re good to go.

Where can I find Nuun?

Sporting goods stores, supplements retailers, select grocery chains around the US and right here on our webstore.

Will Nuun eliminate cramps?

Not only are cramps painful enough to stop you in your tracks, they’re also completely involuntary. Good news is, yes, Nuun can help alleviate cramps by keeping you hydrated better than water alone. Each sip gives you a consistent mix of water and electrolytes to ensure you stay properly hydrated and cramp-free.

What’s in Nuun

  • Four essential electrolytes: sodium potassium, magnesium and calcium.
  • A nice light refreshing flavor that’s not over powering when you’re on the go.
  • A bit of fizzy stuff to ensure it dissolves quickly without having to mix or shake, which disappears once the Nuun tab is completely dissolved.
  • A smidgen of color in the form of riboflavin (vitamin B2) & beet juice depending on the flavor.
  • And of course a dash of love.

What’s not in Nuun?

No sugar, because we didn’t want to upset stomachs or overwhelm taste buds, and we did want to give you more control over your calorie intake.

No artificial colors because neon green isn't necessary for proper hydration.

Why no carbs?

In our opinion, a one size fits all mentality doesn’t work in active lives. We thought it was better to focus on keeping you hydrated and let you decide where your carbs come from. Whether it’s gels, bars or other nutrition sources, you choose what’s best for you.

What flavors does Nuun come in?

Lemon Lime, Tri-Berry, Citrus Fruit, Orange, Banana, Fruit Punch, Grape, Lemon Tea, Strawberry Lemonade, Tropical, and Kona Kola. There’s a flavor just right for all different kinds of taste buds.

What flavors does U Natural Hydration come in?

Can I mix Nuun with other drinks?

Nuun is designed with a balanced ratio of water to electrolytes for optimal hydration. If you find mixing Nuun with other hydration products works for you, fantastic. We’re all about helping people get the best hydration for their needs.

How many servings are in Nuun?

The sturdy lightweight tube is good for 1.5 gallons of electrolyte hydration. There are 12 Nuun tabs per tube. Each Nuun tab makes 16ozs and can easily be broken in half for 8oz mixes. 

Is Nuun gluten-free?

Yes, both Nuun and U Natural Hydration are gluten-free so it’s safe for those with celiac disease or gluten intolerance. Drink up, friends.

Is Nuun vegetarian?

Nuun and U Natural Hydration contain no animal derived raw materials. They are enjoyed by vegetarians, omnivores and carnivores alike.

Does Nuun contain corn?

Nuun and U Hydration have no corn in them, but as some of the ingredients are processed from corn as starting material, we cannot guarantee it is 'corn free' for those of you with corn allergies.

What are electrolytes?

As you might guess from their name, electrolytes are electrically charged, which means that they can conduct electrical impulses. The body needs electrical impulses to make muscle cells contract. The foods we eat and fluids we drink contain mineral salts, which form electrolytes when they dissolve in the fluids in our bodies.

The body has to perform a delicate balancing act to keep water and electrolyte levels just right. For example, whenever sodium levels dip too low, the kidneys are stimulated to produce more urine, which restores the balance by lowering the amount of water in the blood. And when the sodium level gets too high, thirst develops, stimulating the person to drink. A hormone is also secreted by the brain in response to thirst that causes the kidneys to produce less urine. Together, these effects result in dilution of the sodium and the restoration of balance.

Is Nuun carbonated?

A burping athlete is not a good thing, so no, Nuun is not carbonated. When first dropped into water Nuun fizzes to dissolve, but once it’s finished dissolving it will very quickly become still.

Can I eat Nuun?

Nuun was designed to be mixed with water, but we’ve heard of some people eating it anyways. Whether as an experiment or to get your electrolytes in a hurry, it isn’t the most pleasant experience, but it won’t hurt you.

How many calories are in a Nuun?

Nuun is sugar free, so it’s nearly calorie free, but there are a couple calories from the stuff that makes it fizz and dissolve. When you add them up it comes out to less than 8 calories per 16oz drink.

Can my kids drink Nuun?

Sure, Nuun’s great for hydrating and it’s a great way to get kids to drink more water (instead of sugary sodas!).

What about Nuun for a hangover?

We all like to party from time to time. Our office is located above a pub after all. Too much celebrating can lead to dehydration, and since Nuun hydrates more quickly than water alone, you might find us drinking Nuun after our post-race celebrations. Take two Nuuns and call us in the morning.

Can I recycle my Nuun Tube?

Absolutely! The tubes can be recycled at any facility that processes #5 plastics. (find a location) Every tube of Nuun keeps twelve water or traditional sports drinks plastic bottles from being used. A lot of Nuun users have even put their old tubes to some pretty ingenious uses. Unfortunately, the waterproof stoppers aren’t yet recyclable, but we’re working on ways to make them 100% recyclable and still portable, sturdy and waterproof.

Is Nuun legal to race with?

Many are surprised with their increased performance when drinking Nuun, but no worries, Nuun is totally legal. The only thing Nuun is laced with is sodium, potassium, magnesium and calcium.

I’ve seen the Nuun logo on pro athletes - do they actually use it?

Yes, we’re happy to sponsor some fantastic pros who believe in Nuun. A few even claim Nuun as their “secret weapon.” Heck, there are even some talented pros out there who use Nuun even though they display other logos. Now that’s pretty impressive. Ask around, you’ll be surprised.

Nuun’s hypotonic - what does that mean?

A hypotonic solution has a salt concentration that causes water flows into the cells by osmosis. That’s straight from the dictionary, so it’s gotta be true. But in plain English it basically means, a hypotonic solution is the quickest, most efficient way to get water back into your system for optimal hydration.

Can Nuun help prevent hyponatremia?

Absolutely. We’re a bunch of seasoned athletes who’ve been working to combat hyponatremia for years.  Hyponatremia occurs when there’s not enough sodium in your blood stream. If you lose electrolytes (usually through sweating), but are trying to replace them with plain water, you can be at serious risk. Nuun is designed to deliver the perfect balance of electrolytes and water to give you optimal hydration.

Am I dehydrated?

Probably! Experts estimate that only 10% of people are properly hydrated. Since you’re here, you must be one of the smart ones trying to join the ranks of the hydrated—or you’re already there. Signs of dehydration are thirst, irritability, fatigue, headache, cramps and in extreme cases death. Drink Nuun before you have the symptoms!

I'm an incredible athlete - will Nuun sponsor me?

At Nuun we love to support lots of different people who do lots of different things and our Ambassador Program offers definite perks. Right now, we are focused on ambassadors in the USA who are active in social media outlets like Facebook and Twitter. If you have your own website or blog, even better! If you think what you have going on deserves a second look, let us know using our Ambassador Request Form and we will get back to you shortly.

What does “Nuun” mean and where did the name come from?

Nuun, pronounced “Noon,” has generated a lot of rumors and myths of origin. It’s been believed to be everything from the name our founder’s dog to an unexplored island in the Pacific—or even a place in the Legend of Zelda! We enjoy hearing the rumors, so for the time being, we’re going to keep the mystery alive.

Can somebody with high blood pressure use Nuun safely while working out?

Only after checking with a doctor. Some blood pressure conditions are unique and medications can also be an issue. Always check with your doctor before taking something that might affect a health issue, or before undertaking a new exercise program.

What if my pets or kids have eaten the stuff inside the Nuun stopper?

They’ll be fine. Due to our manufacturing practices the stuff in the caps can be either silica gel or bentonite clay, both of which are not dangerous. The worst case would be a stomach ach, constipation, and possibly a tingly feeling on the tongue. Just make sure you drink lots of water. If you are still concerned, here is some more info.

Silica Gel: It’s nothing more than a type of sand. The grains of what looks like clear caviar in the tiny packets are a desiccant. That is, they absorb moisture. You find them in the little white packets in certain food products that will have a longer shelf life if they stay dry; like pepperoni, dried nuts and fruits, or vitamins. So why do the packets include warnings with a skull and crossbones? The packets are “harmful if swallowed” by an infant or pet, as they could choke or aspirate on the packet. However, the grains are loose inside our caps and not inside a packet that could pose a choking hazard.

Bentonite: The little grey grains are rendered from bentonite clay, which is a naturally occurring. Sodium bentonite powder absorbs moisture and is often used in manufacturing like ours as an alternative to silica gel. Bentonite is actually sold in health food stores as a dietary supplement. Because of the substance's bonding properties and smooth consistency, it is added to antidiarrheal preparations, and foods including yogurt, baby milk powders, toothpaste, and pet foods.
