  • 2 per hour, 80-90g of carbs, no GI discomfort.
  • Nrgy units unified in all energy product.
  • Electrolytes in the ratios found in the blood.
  • Optimal carbohydrate composition.

Nduranz was the first to develop a simple system that allows a high energy intake of carbohydrates without digestive problems. This ratio has been scientifically proven to be the most effective from both performance and digestion points of view and has been tested by many athletes who helped us develop the isotonic drink Ndure. But what if an energy gel could have the exact same fuelling properties of the bottle but treat our digestive system with the same kindness as our isotonic drink?

After months of field testing, we present Nduranz Nrgy Gel. It uses a proven Nduranz fuelling system with NRGY units that span across all of our energy and hydration products. Nrgy Gel gives you the same ingredients in the same ratio as the hydration drink: 40-45g* carbohydrates in a 1:0.8 ratio of maltodextrin and fructose. (*The current prototype of the gel contains 40g and not 45g of carbohydrates due to ongoing testing). In addition to salt, it also contains potassium, magnesium, and calcium - matching the ratio found in the blood.

One Nrgy unit - one Nrgy gel - contains the amount of electrolytes found in approximately 400ml of lost sweat, so make sure to drink enough water when taking the gel

It contains no harmful artificial flavours, and the gelling agent is gellan gum - a tetrasaccharide from the microorganism Sphingomonas elodea.

  • The ingredients and the composition match the Ndure isotonic drink
  • Two Nrgy Gels provide you with 80-90g of easy to metabolise and oxidise carbohydrates
  • One Nrgy Gel is sufficient for 1h of moderate-intensity training
  • Introducing unique 1:0.8 ratio of maltodextrine and fructose
  • Energy supply over a period of several hours without irritating the digestive system
  • Reduction of stress hormones through maintenance of blood glucose 
  • Constant fuelling for better functioning of the connection between mind and muscle
  • Sweat-adapted electrolyte content
  • Nrgy unit system spanning across all the products in the category, so you can mix and match freely
  • No sweet aftertaste in the mouth
  • Maintains normal functioning of the mechanical muscle receptors and prevents formation of muscle cramps
  • No artificial flavours

The logic behind our product line is simple - when training hard and long, you need to consume plenty of carbohydrates without irritating the digestive system. This means - 2 Nrgy Units per hour for high-intensity trainings, and 1 Nrgy Unit per hour for moderate-intensiti trainings.

You can mix and match Nrgy unit sources based on your preferences - energy gels or hydration drinks. The choice is yours. 

Don't forget to consult our Fuelling guide.

The task we presented ourselves with was to introduce to the market a drink that is based on strong scientific evidence, as we strongly stand behind our slogan: "Fuelled by research". Here you can follow the latest research. The Nrgy gel contains a mixture of glucose-based carbohydrate source (i.e., maltodextrin) and fructose, but the adopted 1:0.8 ratio is a deviation from the common 2:1 ratio. A ratio closer to unity has been shown to be more effective not only from the perspective of performance, but also regarding glycogen sparing and comfort of the gastrointestinal system. The electrolyte content of Nrgy is in line with the average content of human sweat so that you replace what you lost. Below is some of the research that we found interesting when designing the Gel.

When comparing a gel, a drink, and a bar of a similar carbohydrate content, it was found that the gel is likely the best option from both the digestive system comfort as well as performance. ↪️ https://pubmed.ncbi.nlm.nih.gov/27997257/

This study investigated varying doses of carbohydrates ingested in moderately-trained individuals on performance outcomes and found that 40g per hour is the minimal amount of carbohydrates that are required for improving performance. This is approximately the amount of 1 Nrgy Unit. ↪️ https://pubmed.ncbi.nlm.nih.gov/29301367/

It is a common question - is it better to ingest carbohydrates more frequently but in smaller quantities or less frequently and in bigger boluses? Researchers from Loughborough University tried to answer this question and found that less frequent feedings produced better results. This is one of the reasons why 1 Nrgy unit is so big - not only is it more time efficient to take 2 gels as opposed to 3 per hour, but it is also more effective. ↪️ https://pubmed.ncbi.nlm.nih.gov/32168107/

What is new here?

The Nrgy gel is a complementary product to the Ndure energy drink and has been developed with high-performance athletes in mind. The Nrgy gel uses a scientifically proven composition of carbohydrates in the 1:0.8 ratio between maltodextrin and fructose and electrolytes that resemble the composition of human sweat


The primary goal of an energy-hydration drink (commonly referred to as isotonic drink) is identical to the goal of an energy gel - not so much to supply electrolytes, but primarily to supply energy. In doing so, all the conditions of its utilisation must be met - both absorption and subsequent oxidation. Energy gels are usually less efficient at this than energy-hydration drinks.

During intense activity, we empty glycogen reserves extremely quickly, even 3g per minute, and after just 90 to 120 minutes, it can happen that our performance begins to decline.  When the concentration of glucose in the blood begins to fall, we feel this as a "wall" - the brain no longer functions normally and our muscles slow down.

That is why we enjoy energy gels. But the energy gels most often contain carbohydrates that target the glucose transporter. This means that we can consume and utilise only 50g or maybe 60g of carbohydrates per hour, which is not enough to reduce the reliance on liver and muscle glycogen. If we consume more drinks or gels, we also get more carbohydrates in the digestive tract, but because the limiting factor is the transport from the intestine into the bloodstream, intakes higher than 60 g/h will simply result in carbohydrates being left unabsorbed in the intestines.

Nrgy is a high-energy gel that will in its final version provide you with 45g* of carbohydrates in a 1:0.8 ratio of maltodextrin and fructose (*the current prototype gel contains 40g and not 45g of carbohydrates DUE TO THE TESTING PHASE). With electrolytes in the ratio found in the blood, it is the "gelly" version of Ndure energy-hydration drink that is being utilised at the same level, with the same effect, and with the same subjective perception. Our 1:0.8 maltodextrin to fructose ratio has been scientifically proven to be the most quickly and fully absorbed due to the utilisation of multiple transporter types - and the difference is so noticeable that you will be impressed at the very first "train hard or go home" moment.


We have mentioned that the limit of intake of glucose-based nutrients is 60 g/h. If we ingest more than this, carbohydrates will be left unabsorbed in the intestines causing gastrointestinal problems.

Nrgy Gel utilises a mixture of different carbohydrate types (1:0.8 ratio between maltodextrin and fructose). Maltodextrin is utilising the glucose transporter. Maltodextrin is nothing more than an interconnected glucose molecule with a non-sweet taste, featuring the same high glycemic index as glucose. Fructose, on the other hand, utilises another transporter. With our scientifically defined ratio, we can absorb more carbohydrates during exercise than by overloading only on one type of carbohydrate.

This simple yet overlooked fact allows the absorption and oxidation of 90-120 grams of carbohydrates per hour, no matter if we prefer hydration drinks, energy gels, or both, without causing significant stress on the digestive system.


An isotonic solution apparently suggests that the basic role is in the solution itself, in which minerals are dissolved in a certain ratio. However, this is not entirely true, as blood is not just made up of water and electrolytes - it contains glucose, salt, lipoproteins, sterols - it is a relatively thick fluid. And the tonicity of a fluid, in this case blood, is not only affected by electrolytes, but also by glucose, among other things

Ideally, water as a solvent and electrolytic forms of minerals as a solute would form a blood-balanced isotonic environment. But if we look only at the amount of sugar in the isotonic and compare it with the amount of glucose in the blood, we see that the drink cannot be isotonic and at the same time contain the same amount of electrolytes with respect to the blood. Five litres of blood contain only about three grams of glucose, and we have more than 40g of sugar per half a litre of the liquid. So, if we want to have an isotonic drink, we need to reduce the amount of electrolytes.

But there is nothing wrong with that! We need to look at what happens during exercise. We lose electrolytes through sweating. But the amount of these is much lower in sweat than in blood. It would therefore be ideal for the drink to have the same electrolyte composition as sweat - this would replace what was lost.

We see that isotonicity is problematic and we can simply solve that by replacing an isotonic drink with calorie-saturated energy gels. Osmotically active particles travel from an area with a higher concentration to an area with a smaller one. There is always more salt in the blood than in any (still edible) isotonic drink, and there is much less sugar in the blood than in the isotonic drink. But the cell membrane is not so much interested in what goes through as the concentration gradient of all the osmotically active particles combined. The function of an isotonic drink is therefore much more similar to that of a gel than we think - due to the overall high amount of sugar in it, it is slightly hypertonic, which makes it easier for salt to get into it.

The electrolytes in the high-energy gel are therefore adjusted in proportion to those found in the blood and which we lose through sweating. But this is not enough, we need a high amount of effectively available carbohydrates; one energy unit - one high-energy gel - recovers approximately 400ml of lost sweat, and two units 800ml (this is enough for moderately demanding workouts in a warm environment, while it makes sense to get one unit from Ndure drink during intensive and long workouts, as we can also lose more sweat and thus electrolytes).


The logic behind our product line is simple - when training hard and long you need to consume and efficiently utilise 90g of CHO without stomach complaints (2Nrgy units). But because the progress also includes recovery rides and shorter training, our products are divided into 40-45g portions.

As a general rule of thumb for most training sessions:

  • one Nrgy unit (one Nrgy gel or one Ndure drink) per hour.

For long, high-intensity workout and strenuous races:

  • two Nrgy units (two Nrgy gels, two Ndure drinks, or one Nrgy gel and one Ndure drink).

Don't forget to consult our Fuelling guidelines.

Preparing for a race, following the rule of two Nrgy units - 90g of absorbed as well as oxidised carbohydrates per hour - improves performance in three major areas:

  • provides the working muscles with the energy needed for muscular work over a period of several hours;
  • reduces fatigue and maintains concentration due to a reduction of stress hormones and maintenance of glucose, which is essential for the functioning of mental processes and the parasympathetic nervous system;
  • prevents muscle cramps, as normal electrochemical communication between neurotransmitters and mechanical muscle receptors is maintained.

We often burn glycogen at a rate of even more than 3 grams per minute, and we can simply feel our energy being somehow externally limited, despite the fact we wish to push further. Energy sensors in our body have the ability to detect a decrease in glycogen far before it runs out, which causes the nervous system to preemptively limit our physical ability. The only thing we can do to offset this is to keep ingesting carbohydrates during exercise. But these carbohydrates must not cause discomfort to the stomach, must be absorbed, and in the end fully utilised.
