Join us on our quest to create the optimal fuel for endurance athletes.
Optimal Fuel

If you're looking for optimal fuel, Nrgy Unit Drink is pretty much as close as it gets.

Why is that?

Two simple reasons: Nduranz Carbohydrate Ratio and Nduranz Electrolyte Mix.

But you have probably stumbled across the different versions of our high-efficiency carbohydrate drink, and you might be confused. Which one is better? Which one should I choose? What's the difference?

Let us clear that up for you.

But first, let's take a look at why Nrgy Unit Drink is your optimal fuel.

Where's the Science?

Everyone says their formulas are based on science, but then proceed to make products that seem to go directly against it. If that puzzles you, you are not alone. We are puzzled by it as well, and it is basically the reason why years ago we had decided to found Nduranz.

We are fully aware that science is an ongoing process, and what might be considered optimal today may very well change in the future. Nevertheless, extensive research across the globe has in fact yielded many tangible results. And while some results may be considered inconclusive, there are others that have been over and over again proven in labs and confirmed in practice by top-level athletes.

We are all about innovation, and we like to test uncharted waters, but our foundation is deeply rooted in scientifically-sound principles. If your core is unstable, then all experimentation will lead to random outcomes.

This is why all our products are based on the discoveries of the latest research. When it comes to science and quality, we never compromise.

Nduranz was founded to actually use science in sports nutrition.

Which brings us to the two reasons why Nrgy Unit Drink is as close to optimal fuel as you can find.

Nduranz Carbohydrate Ratio

For a very long time, endurance athletes have been consuming only glucose as their fuel during intense exercise.

The purpose of consuming carbohydrates in any form and especially glucose, which is a fast-acting simple sugar, is to maintain sufficient carbohydrate availability for as long as possible by sparing glycogen stores within the body and taking over as a carbohydrate source when levels are low.

The problem is, if you consume only glucose, you can only absorb up to 60 grams of carbohydrates per hour. Considering the high energy requirements of top-level endurance athletes, this is not nearly enough.

To make matters worse, if you consume more glucose than that, it will stay in your gut and cause digestive issues.

Is there a solution?

Luckily, there is. It's called fructose.

By combining glucose and fructose, you can use both carbohydrate transporters in your body, which increases absorption rates to 90-120 grams of carbohydrates per hour. So we're looking at a 50 or 100% increase in effectiveness.

While many carbohydrates drinks today use a combination of glucose and fructose in their formulas (surprisingly, many do not), most of them ignore another very important aspect. The ratio.

Professor David S. Rowlands researched the optimal ratio of glucose and fructose and found that it is 1:0.8 in favor of glucose. While this ratio may be micro adjusted in the future, it is the best ratio confirmed by science today for optimal absorption of carbohydrates during intense exercise.

This is why all our fueling products are based on this ratio.

The 1:0.8 ratio of glucose and fructose is optimal for high carbohydrate absorption.

Nduranz Electrolyte Mix

Optimal hydration during intense exercise is crucial. 

Why?

Because pretty much all your body functions depend on it.

What is optimal hydration then, you may ask?

It is a combination of ingesting fluid (at least 500 ml of water per hour) and preserving the electrolyte balance in your bloodstream.

Many athletes make the mistake of drinking too much water, which dilutes the concentration of electrolytes in their body. This is bad. You need electrolytes. They are the ones that make everything work.

Pretty much all sports drinks contain minerals aka electrolytes. The thing is, most of them contain the wrong ones.

What are we talking about?

For starters, magnesium. There is this persistent myth that magnesium prevents muscles cramps. It doesn't. What prevents muscle cramps is a sufficient intake of carbohydrates before and during exercise.

What does magnesium do, then? Cause digestive issues. The thing is, magnesium is a crucial mineral, but you don't lose much of it during intense exercise, so supplementing it in large quantities makes no sense. Because magnesium affects the osmolality of the drink, too much of magnesium in the drink can make the drink very concentrated and actually cause water to be drawn from the bloodstream to the intestines and in turn cause gastrointestinal issues.

What you do lose in large quantities, though, is sodium. So mostly salt, if you prefer.

Nduranz Electrolyte Mix contains the minerals in a concentration as close to human sweat as possible. Because sweat is different for every person, it is impossible to get the optimal concentration for everyone, but this is as close as it gets.

Nduranz Electrolyte Mix replaces what you actually lose in your sweat.

The Three Versions of Nrgy Unit Drink

Now we finally get to the point. Why are there three different versions of Nrgy Unit Drink and which one is the best for you?

The answer is more straightforward than you may have imagined.

Carbohydrate drinks for endurance athletes

So, let's get to it.

Nrgy Unit Drink

For all intents and purposes, Nrgy Unit Drink is your optimal fuel.

It is based on Nduranz Carbohydrate Ratio and Nduranz Electrolyte Mix and has several benefits:

  • Gives you high energy availability during intense exercise
  • Provides (close to) optimal hydration during intense exercise
  • Doesn't cause digestive issues or gut discomfort
  • Prevents muscle cramps by providing sufficient amounts of energy
  • Available in many refreshing and delicious flavors
  • Allows you to choose between versions with and without citric acid (while citric acid improves the taste, it can also harm your teeth)

Nrgy Unit Drink is the optimal fuel for most endurance athletes.

While most endurance athletes should stick to Nrgy Unit Drink as their fuel of choice, there are also athletes who push themselves beyond the normal limits. It is for those athletes that we have created the other two versions.

Nrgy Unit Drink 90

Both the Nrgy Unit Drink 90 and regular Nrgy Unit Drink have the same amounts of electrolytes when mixed with 500ml of water - what is different is the amount of carbohydrates.

Nrgy Unit Drink 90 contains double the amount of carbohydrates per serving (that amounts to 90 grams of carbohydrates) and is designed, flavor-wise, for high carbohydrate consumption.

Practically speaking, this allows you to pack double the amount of energy in your sports bottle. While this wasn't the reason we had created this drink, we noticed many athletes adopted it for this purpose.

However, keep in mind that during intense exercise you need to ingest a sufficient amount of fluid. If you do it with Nrgy Unit Drink 90, you may quickly exceed your desired energy intake.

This is why we recommend Nrgy Unit Drink 90 only to the athletes with extreme energy requirements (90 to 120 grams of carbohydrates per hour).

Nrgy Unit Drink 90 contains double the amount of carbohydrates per serving.

High carbohydrate intake Use this fuel for your most intense challenges.

Nrgy Unit Drink Buffer

The previous two versions of Nrgy Unit Drink are your main source of fuel. They are both based on Nduranz Carbohydrate Ratio and Nduranz Electrolyte Mix, and they can both be used to fuel your entire exercise.

Nrgy Unit Drink Buffer is different.

While it is based on the same carbohydrate ratio, it doesn't pack the full suite of minerals. Actually, it only contains sodium bicarbonate, which is the sole purpose of its existence.

Sodium bicarbonate is one of the most researched supplements in endurance sports. It has been proven time and time again it is extremely efficient in improving your endurance in short bursts of extreme intensity. In simple terms, it improves your sprints.

Sodium bicarbonate also has other positive effects, such as regulating your body's pH levels. Many of our athletes reported increased wellbeing in their stomach after consuming sodium bicarbonate.

Nrgy Unit Drink Buffer is also special because we've actually managed to make it drinkable. If you ever tried to consume sodium bicarbonate, you know very well its taste is quite heavy, to say the least.

Sodium bicarbonate drinkUse this fuel to improve your sprints.

However, consuming too much sodium bicarbonate also has downsides, so you should never exceed the recommended ingestion protocol. For this reason, Nrgy Unit Drink Buffer is not a standalone fuel, but rather it is an additional source of fuel you use in combination with our other fueling products.

Sodium bicarbonate allows you to improve your endurance in very intense efforts (1-15 minutes) by 3-5%.

Conclusion

Nrgy Unit Drink is the optimal fuel for most endurance athletes during intense exercise because it is based on the combination of glucose (maltodextrin) and fructose in the 1:0.8 ratio, proven by science to be optimal for highest carbohydrate absorption, and replaces the minerals you actually lose in your sweat.

Nrgy Unit Drink 90 is its bigger brother, intended for top-level athletes who require extreme energy intakes of 90 to 120 grams of carbohydrates per hour.

Nrgy Unit Drink Buffer is designed to improve your high end power output by 3-5%, but you must be careful to follow the sodium bicarbonate ingestion protocol.

Hopefully this clears up all confusion you might have regarding Nrgy Unit Drink and its variations. If in doubt, you should use Nrgy Unit Drink.
