Don't know which gel to choose? 👇

Nrgy Gel 45 is designed for high-performance athletes who need a high carbohydrate intake and optimal hydration without digestive issues.

Each energy gel 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 Gel 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 Gel 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 Gel 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 Gel 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.

If you're chasing peak performance, this is the most efficient energy gel your body can handle!

  • Optimized for high energy intake
  • Preserve glycogen stores
  • Sustain optimal hydration
  • Prevents muscle cramps
  • No digestive issues
  • Simplifies fueling
  • No artificial sweeteners
  • Informed sport certified

Take 1 to 2 energy gels per hour of intense exercise.

Used by Elite Athletes

These gels are key in my sport. They give me the energy I need to keep going and perform at my best for hours. What I love most is how easy they are to digest — no stomach issues at all — and they come in delicious flavors. They let me take in a lot of carbs during training and races, which helps me go full gas.

Claudio Díaz Castán

The NRGY Gels 45 give me fast energy and carbs when I need them. With all the different tastes I never get tired of them that helps a lot during long training sessions or an IRONMAN race.

Lukas Stahl

Fuelling well both during and between training is such a crucial part of high performance in triathlon. I use the Nrgy Gel 45 both in training and racing, allowing me to absorb a very high amount of carbs with zero GI issues. The added bonus of plenty of sodium per serving is super important for me too. 

Zack Cooper

In long-distance running, staying fueled is key but finding the right product isn’t always easy. You need something that’s fast-absorbing, easy on the stomach, and won’t slow you down. With Nrgy Gels 45, I’ve finally found my go-to fuel: great taste, smooth digestion, and a constant boost of energy that keeps me going strong, mile after mile.

Pasquale Selvarolo

The Nrgy Gel 45 is my go to fuel during long runs. It’s light, fits in my pocket so I can take it with me easily. I find it ideal to take one for every 60 minutes that I run.

Who Should Use Nrgy Gel 45?

Built for peak performance, yet suitable for any athlete pushing their limits.

Whether you're a cyclist chasing a PR, a marathoner looking to prevent muscle cramps, or a triathlete aiming to fuel without digestive issues, Nrgy Gel 45 helps you go longer, stronger, and without gut drama.

Need an efficient, gut-friendly gel that keeps you energized and hydrated? Nrgy Gel 45 is your go-to.

How Does Nrgy Gel 45 Work?

Nrgy Gel 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

If Nrgy Gels are your sole energy source, consume 1 to 2 Nrgy Gels per hour.

1 gel for low intensity.

2+ gels for high intensity or racing.

For best results, combine Nrgy Gel 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 the risk of digestive issues.
