Nrgy Drink 45 is the optimal fuel for high-performance athletes who need a high carbohydrate intake and optimal hydration without unnecessary ingredients and digestive issues.

Each serving delivers 45 grams of carbohydrates using the scientifically proven 1:0.8 glucose to fructose ratio and contains the Nduranz Electrolyte Mix® that replicates exactly what you lose through sweat.

CARBOHYDRATE RATIO

Nrgy Drink 45 is based on the Nduranz carbohydrate ratio, a 1:0.8 ratio between glucose (maltodextrin) and fructose.

It is scientifically proven to be the optimal ratio, which allows the highest absorption of 90 grams of carbohydrates per hour without burdening your digestive system and causing digestive issues.

ELECTROLYTE MIX

Nrgy Drink 45 contains the Nduranz Electrolyte Mix®, an advanced mix of minerals that matches the electrolytes you lose with sweat.

This mix enables optimal hydration during intense exercise without causing digestive issues, which are a common downside of many electrolyte formulas.

COMBINING WITH OTHER FUELING PRODUCTS

For best results, combine Nrgy Drink 45 with other Nduranz fueling products. They all use the same carbohydrate ratio, and those that include electrolytes share the same Nduranz Electrolyte Mix®minimizing digestive issues.

INFORMED SPORT CERTIFIED

Every batch of Nrgy Drink 45 is tested for banned substances under the Informed Sport program. That means you can fuel with confidence — your performance stays clean and your reputation safe.

Keep your energy high and hydration on point with Nrgy Drink 45!

Nrgy Drink 45 vs. Nrgy Drink 90

Nrgy Drink 90 is a sports drink adapted for higher energy intake. Although it offers the same amount of CHO per scoop (22.5 g) as Nrgy Drink 45, the amount of electrolytes and the strength of the taste are adapted to the higher amount in a single bottle.

This way, Nrgy Drink 90 ensures that you get just the right amount of electrolytes in one serving (4 scoops) and a suitably strong taste.

If you were to mix 2 portions of Nrgy Drink 45 (4 scoops) in a bidon, you would have double the amount of electrolytes in one bottle and a drink with an extremely strong taste. The former, in particular, opens up the possibility of digestive problems. 

Nrgy Drink 90 also allows you to intake more CHO with less fluid, as you can intake 90 grams with just 500 ml of water. Nrgy Drink 45 requires 1000 ml of water for an intake of 90 grams.

Trusted by professional athletes

This is my go to hydration drink before and during training. The version without citric acid is gentle on the stomach which is very important for athletes like me with gastric sensitivity. I’ve tested many products, but this Nrgy Dirnk 45 is the one that works best for me, every single day. It gives me steady energy without any digestive issues, and I use it for all types of training. It’s a staple in my routine.

Madalina Florea

The Nrgy Drink 45 is perfect for intense sessions, when I need energy for up to 2-3 hours. It is easy to take, tastes great and makes for the perfect fuel!

István Dániel Szögi

Nrgy drink: my new water :) drinking it every day during training, keeps me well hydrated, really like the lemon taste.

Tommy Giacomel

I find that the Nrgy Drink is easy to digest and goes down well even during intense sessions in hot weather conditions. The refreshing flavours, especially the watermelon, make it enjoyable to drink, so I don't forget to hydrate and can stay on top of my energy and hydration needs during long runs. It's also easy to use alongside the Nrgy Gel 45, making it simple to keep track of my carbohydrate intake per hour, and stay consistently fuelled through training and racing.

Chelsea Creak

During races, I want to make the most out of every sip I carry—by adding Nrgy Unit Drink, I combine hydration with liquid carbs to keep my energy levels high. Since electrolytes are already included and the powder dissolves easily, it's super practical to use on the go and easy to carry as a spare.

Julia Glaus

It’s a product that accompanies me in my daily training, and its key advantage shows in the summer, when high temperatures cause significant fluid loss during workouts. That’s when the advanced electrolyte mix plays an important role, reducing the risk of cramps. The fruity flavor is pleasant and refreshing.

Who Should Use Nrgy Drink 45?

Perfect for any endurance athlete who needs consistent energy, optimal hydration, and cramp prevention without upsetting the stomach.

Whether you're a cyclist fueling a long ride, a triathlete in search of reliable fuel, or a runner training for a marathon, Nrgy Drink 45 keeps your energy high and hydration on point.

Training in the heat or planning long hours on the road? Nrgy Drink 45 keeps you performing at your best.

How Does Nrgy Drink 45 Work?

Nrgy Drink 45 combines two essential components: the scientifically backed 1:0.8 glucose to fructose ratio for maximum carbohydrate absorption, and the Nduranz Electrolyte Mix®, a mineral profile mirroring sweat for optimal hydration.

Together, they deliver fast energy, optimal hydration, and minimal digestive stress.

It works by:

  • Delivering up to 90 g of carbs per hour without stomach issues
  • Replacing key electrolytes to maintain hydration and muscle function
  • Preventing muscle cramps and supporting consistent energy output

Recommended Use

Consume 1 to 2 servings per hour of intense exercise.

For 1 serving, mix 2 scoops with 500 ml of water (in hot conditions 750 ml).

The energy that fuels

Impressed of this great product!
It's the proper fuel for any ride. It has a good taste, not too strong to cause any gut issues but just tasty enough to make every sip a pleasant one.
Besides, it contains the right mix of ingredients to keep away any cramps or dehydration. Mixing it with a gel, hits the right carbs/hour needed for an energising ride. And the legs will surely appreciate this!
Love it, both lemon and orange!

Hi Stanca, we're thrilled to hear you love Nrgy Drink 45 and that it keeps you energized on your rides! Thanks for sharing your positive experience and for your support. Enjoy your next adventure!

Best regards,

Lekkere drank

Lekkere drank, niet te zoet.
Persoonlijk moeilijk te vergelijken met andere sportdranken want te warme omstandigheden.

Dank je wel, Peter! Fijn om te horen dat je de Nrgy Drink 45 lekker vindt. Hopelijk zijn de omstandigheden snel weer beter zodat je het nog beter kunt vergelijken.

You’ve tried the others,now try the better stuff.

Ive been using the 45 for sometime now and it’s my go to energy drink for all my rides.
Up to now ive only used the lemon but I’ve recently bought the orange so hopefully it’ll be every bit as gentle on my stomach as the lemon . It certainly helps me to get through some long rides.
I’ve tried to convince club members to try your products but they seem totally blinkered and keep with the same old same old stuff. You can guess the ones?

Thanks so much, Michael! 😊 We're delighted that NRGY Drink 45 has become your go-to for long rides and that the Lemon flavour has been so gentle on your stomach. We hope you enjoy the Orange just as much! And thank you for spreading the word to your club mates — sometimes people need a little extra convincing before they discover something new 😉💪‍♂️

Fantastisch spul

Fantastisch spul.
Ik ben overgestapt van de energiedranken en dorstlessers uit de supermarkt naar de energey 45.

Ik heb veel minder honger na de training, en hoef nu niet meer met 2 complete maaltijden in mijn rugzakje naar kantoor te fietsen.

Kleine waarschuwing, als je de nergey drank, en wat 45g gelletjes en nog een recovery reepje na de rit neemt ligt dat best wel zwaar op de maag.

Begin met OF een bidon OF een gelletje OF een reepje per uur .. EN/EN/EN is net even te veel van het goede ;) ....

Hallo, bedankt dat je dit deelt! Geweldig om te horen dat de overstap van supermarktproducten zo'n praktisch verschil heeft gemaakt. Geen gesleur meer met twee maaltijden naar kantoor! 😄

En dat is ook een heel waardevolle tip voor andere sporters: beginnen met één product tegelijk en van daaruit verder opbouwen is uitstekend advies. Alles met mate! 😊 Bedankt dat je de tijd hebt genomen om dit te delen!

Prima spul. Man met hamer niet meer gezien.

Geeft idd energie onderweg, en ik voel me ook de volgende dag minder mee na lange ritten (bv120km). Smaakt niet vies, geen last van maag.

Hallo, hartelijk dank voor je feedback — we zijn erg blij om te horen dat het je tijdens je ritten van energie voorziet en ook helpt bij het herstel! 💪

En nog even… een korte vraag 😄 waarom staat er een afbeelding van een bijl op??

Davvero gradevole!

Molto soddisfatto di questo integratore perché non esageratamente dolce come altri della concorrenza, incolore, davvero utile nel senso che si sente la diffrenza di energia nelle uscite in bicicletta e nei trail a pidi in montagna.

Grazie, per noi è estremamente importante che il prodotto non contenga coloranti :)
