Nrgy Drink 45

£24.99 £12.99

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. 

  • Optimized for high energy intake
  • Sustains optimal hydration
  • No digestive issues

  • Prevents muscle cramps
  • Preserve glycogen stores
  • Simplifies fueling
  • No artificial sweeteners
  • Informed sport certified

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).

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).

Use the Nduranz Fuel Calculator to easily estimate your required energy intake during exercise.

Top product waarmee ik tot 90 gram koolhydraat per uur kan nuttigen

Tijdens lange etappe's in een meerdaags evenement heb ik de NRGY Drink 45 gebruikt in combinatie met repen en gels om tot 90 gram koolhydraten in te nemen. Met dit product lukt me dit prima en heeft voor mij het voordeel dat het makkelijker drinkbaar is dan de 90 variant en het heeft me geen darmproblemen gegeven terwijl ik het veel heb gebruikt. Voor mij een top product

Dank je wel, Gerrit! Wat fijn om te horen dat de Nrgy Drink 45 je zo goed helpt tijdens je lange evenementen. Heel veel succes met al je verdere trainingen en doelen!

Groetjes,
Jouw 4Endurance team

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,
4Endurance Team

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.
