Nrgy Gel 45 with Caffeine Box

£44.99 £22.99

Nrgy Gel 45 with Caffeine is designed for athletes with high energy demands and who want a gel that provides carbohydrates, electrolytes, and caffeine.

CAFFEINE BOOST

Nrgy Gel 45 with Caffeine is available with 65 mg or 130 mg per gel, so that you can adjust your intake based on the session or your personal tolerance. A red top clearly marks the caffeinated option, making it easy to identify even when going hard. 

1:0.8 CARBOHYDRATE RATIO

Nrgy Gel 45 with Caffeine contains glucose (as maltodextrin) and fructose. Because these carbohydrates are absorbed through different transporters in the gut, combining them allows your body to absorb more carbohydrates.

This scientifically backed 1:0.8 ratio further improves absorption, making it possible to consume 90 grams per hour or more without overloading the digestive system. The result is a steady supply of energy that supports performance during long or high-intensity sessions.

45 G OF CARBS PER GEL

Each gel provides 45 grams of carbohydrates, making it one of the most energy-dense gels available. The high dosage means you won't need to consume as many gels per hour to meet your energy needs, allowing you to focus on performance instead of fueling.

Despite being more concentrated, the gel maintains a smooth texture and balanced flavor, making it easy to consume hour after hour.

ELECTROLYTE MIX

Nrgy Gel 45 with Caffeine contains the Nduranz Electrolyte Mix®, a patented blend of sodium, chloride, potassium, and magnesium. The mix mirrors the amount of electrolytes lost through sweat during exercise, allowing you to replace what you lose.

DESIGNED FOR MODULARITY

All Nrgy products contain 22.5, 45, or 90 grams of carbohydrates per serving. These standardized amounts make it easy to combine products to reach 90 grams of carbs per hour. 

Mixing and matching products allows you to create a modular system: gels and bars provide concentrated energy, sports drinks provide energy and hydration, and electrolyte-free products act as an energy top-up.

  • Preserves glycogen stores
  • High carbohydrate amount per gel
  • 1:0.8 ratio supports high energy intake without digestive issues
  • Contains caffeine to increase alertness, focus, and time until exhaustion
  • Prevents muscle cramps
  • Contains key electrolytes to support hydration
  • Informed Sport certified
  • Vegan, gluten-free, and no artificial sweeteners

Nrgy Gel 45 with 65 mg of caffeine (Cherry and Mango flavors): 
Consume up to 2 gels per hour, depending on your carbohydrate needs and tolerance. These gels can be combined with non-caffeinated gels, drinks, or bars to help meet your hourly carbohydrate targets. Do not exceed 5 gels per day. 
Nrgy Gel 45 with 130 mg of caffeine (Coffee Amarena flavor): 
Consume up to 1 gel per hour. These gels can be combined with non-caffeinated gels, drinks, or bars to help meet your hourly carbohydrate targets. Do not exceed 3 gels per day. 

Warning: These products contain caffeine. They are not suitable for children, pregnant or nursing women. Caffeine can cause unwanted side effects. We recommend starting with 1 energy gel with caffeine during your workout and adjusting intake based on your tolerance and needs. Be mindful of your total daily caffeine intake when taking caffeinated gels.

Who should use Nrgy Gel 45 with Caffeine?

Nrgy Gel 45 with Caffeine is designed for endurance athletes with high energy demands, including cyclists, runners, triathletes, and long-distance athletes. It is particularly suited for long or intense training sessions and races where rapid carbohydrate absorption is critical.

Why does Nrgy Gel 45 with Caffeine use a 1:0.8 glucose–fructose ratio?

This ratio allows carbohydrates to be absorbed via multiple intestinal transport pathways, increasing total carbohydrate uptake while reducing the risk of gastrointestinal discomfort compared to single-source carbohydrate products.

How many gels should I take per hour?

Your intake should be based on your carbohydrate and caffeine targets, as well as your individual tolerance.

If you’re sensitive to caffeine or unsure how you’ll respond, start with one Nrgy Gel 45 containing 65 mg of caffeine (Cherry or Mango). This allows you to assess tolerance without overdoing it.

From there, you can increase to two gels with 65 mg of caffeine per hour, or use one gel with 130 mg of caffeine per hour, depending on your needs and the intensity of your session. You can also combine the caffeinated Nrgy Gel 45 with non-caffeinated products to increase carbohydrate intake without raising your caffeine intake.

Should I take Nrgy Gel 45 with Caffeine with water?

Yes. Taking Nrgy Gel 45 with Caffeine with water supports digestion and carbohydrate absorption, especially at higher intake levels.

Can Nrgy Gel 45 with Caffeine be combined with other fueling products?

Yes. Nrgy Gel 45 with Caffeine can be used alongside other fueling gels, drinks, and bars. To reduce the risk of gastrointestinal disturbances, we recommend using Nrgy Gels 45 with Caffeine with other Nrgy fueling products, as these all use the same 1:0.8 carbohydrate ratio. Always be mindful of total carbohydrate and electrolyte intake when combining fueling products. 

Is Nrgy Gel 45 with Caffeine suitable for hot conditions or high-sweat sessions?

Yes. Nrgy Gel 45 with Caffeine contains electrolytes, so it is suitable for use in warmer conditions or during sessions with higher sweat rates, where electrolyte losses are greater.

Can Nrgy Gel 45 with Caffeine cause stomach issues?

Nrgy Gel 45 with Caffeine uses dual carbohydrates in a 1:0.8 formula. This formula improves absorption and reduces the likelihood of stomach issues. However, carbohydrate tolerance varies by individual, so athletes should practice using it during training before race day. 

Is Nrgy Gel 45 with Caffeine vegan and gluten-free?

Nrgy Gel 45 with Caffeine is suitable for a vegan diet and does not contain gluten.

Why does the nutrition label say that Nrgy Gel 45 with Caffeine contains 22 g of sugar?

Because not all carbohydrates in Nrgy Gel 45 with Caffeine come from sugars. A significant portion of the carbohydrates is provided as maltodextrin, which is not classified as a sugar on nutrition labels. When combined with fructose, this allows the gel to deliver a total of 45 grams of carbohydrates, even though the nutrition label states a lower sugar content. 

Does Nrgy Gel 45 with Caffeine contain electrolytes?

There are three versions of Nrgy Gel 45. The version with the black top contains electrolytes. The version with the white top is electrolyte-free. The version with the red top contains electrolytes and caffeine.

Which Nrgy Gel should I use? 

It depends on your training type and personal needs.

  • Choose Nrgy Gel 45 with electrolytes when you need an all-in-one fuel and electrolyte solution. 
  • Choose Nrgy Gel 45 without electrolytes when you are getting electrolytes from other sources or electrolyte needs are lower. Separating carbohydrates and electrolytes also allows you to create a more precise, modular fueling strategy.
  • Choose Nrgy Gel 45 with caffeine (contains electrolytes) when you want the performance-enhancing effects of caffeine, such as increased focus during a decisive race segment, an attack, or a strong finish.
  • Choose Nrgy Gel 22.5 without electrolytes when you don’t need a full 45 grams of carbohydrates, such as during shorter efforts or when you want to combine it with other Nrgy products to fine-tune your fuel intake.

Should I use Nrgy gels or Nrgy drinks?

Both Nrgy gels and drinks deliver fast-absorbing carbohydrates in the 1:0.8 ratio and are available with or without electrolytes. The choice depends on your preference and situation.

  • Nrgy Gels: Great for situations where you need a concentrated dose of carbs in a small, portable form. They’re easy to carry and use mid-race, but you’ll need to consume fluids separately.
  • Nrgy Drinks: Better for when you want carbohydrates and fluids in one product and portability is less of a concern. 

Many athletes use a combination of both gels and drinks to meet their fueling needs. 

Does Nrgy Gel 45 with Caffeine contain any banned substances?

No. Nrgy Gel 45 with Caffeine is free from substances banned by the World Anti-Doping Agency (WADA). It is also Informed Sport Certified, which means each batch is tested by an independent laboratory for banned substances and manufactured under strict quality-control standards. This certification gives athletes confidence that the product is safe to use in competition.

What’s the difference between “salt” and “Nduranz Electrolyte Mix®” on the label?

Salt refers specifically to sodium chloride (NaCl), which contains both sodium (Na) and chloride (Cl). The Nduranz Electrolyte Mix®, on the other hand, is a blend of electrolytes that includes salt as well as other minerals like potassium and magnesium. This is why the total amount of the Nduranz Electrolyte Mix® is higher than the listed salt content. The nutrition label also shows the total sodium and total chloride from the mix, helping athletes track electrolyte intake more accurately for hydration and performance.

Which electrolytes are in the Nduranz Electrolyte Mix®?

The Nduranz Electrolyte Mix® contains a blend of key electrolytes to support hydration and muscle function. This includes sodium, potassium, magnesium, and calcium. These electrolytes come from a combination of salts and citrate forms, which are designed to be easily absorbed during exercise.

Which maltodextrin is used in Nrgy Gel 45 with Caffeine?

Nrgy Gel 45 with Caffeine uses corn-derived maltodextrin with a dextrose equivalent (DE) of approximately 19. This DE value indicates the degree of hydrolysis and helps determine how quickly the carbohydrate is digested and absorbed.

Trusted by Professional Athletes

Especially in the final 2 hours of a race, this gel delivers the extra boost and focus needed to maintain performance. Also ideal when intense or chaotic race situations are coming up — when it’s all about staying 100% focused and performing at your best.

Lasse Reuss

On ultra trails, I rely on Nrgy Gels 45 with Caffeine as an easy source of carbs and caffeine that keeps my energy stable. The caffeine gives me that extra push to stay sharp on long, technical sections — and nothing beats the refreshing mango flavor out in the mountains.

Julia Glaus

The Nrgy Gels 45 with Caffeine are my go-to for long races and hard training sessions. I really like how easy they are to digest, even when I’m pushing hard, and the caffeine gives me just the right mental boost without feeling jittery. The taste is great, not overly sweet, and it keeps my energy steady all the way to the finish line.

Nico Kautter

When someone mentions caffeine gels, everyone thinks of that horrible taste. However, Nrgy Gel from Nduranz is super tasty and only slightly different in flavor compared to the non-caffeinated ones. Cherry is by far my favorite! Also, having multiple options, ranging from 65 mg to 130 mg of caffeine, is great and super important.

Josip Meštrić

The gel is packed with 45g of carbs and just the right amount of caffeine for an extra boost of focus. The texture was smooth, with a nice balance of sweetness and saltiness. Definitely a go-to for a hard workout, or a long run when I need to dig a little deeper.

Catalin Sorecau

I use this product during the races, especially in the first part of them so the caffeine have the right time to be absorbed and get the benefits of it. Favourit flavour: Mango.

Peter Cevini

Who Should Use Nrgy Gel 45 with Caffeine?

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

Whether you're a cyclist attacking a climb, a runner fighting through the final 10k, or a triathlete staying sharp through transition and beyond — this gel keeps your legs firing, and your focus locked in.

Need energy with an extra edge? Nrgy Gel 45 with Caffeine has your back.

How Does Nrgy Gel 45 with Caffeine Work?

Nrgy Gel 45 with Caffeine combines three performance-driving components: the scientifically backed 1:0.8 glucose to fructose ratio for maximum carbohydrate absorption, the Nduranz Electrolyte Mix® for optimal hydration, and a measured dose of caffeine to amplify energy and mental focus.

Together, they deliver fast energy, optimal hydration, reduced fatigue, 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
  • Reducing perceived exertion and delaying fatigue with caffeine

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.

Gut, aber geschmacklich noch Luft nach oben

Das Gel ist super, ist geschmacklich nur nicht auf dem Level von Organe oder Zitrone. Allumfassend bestens, vor allem durch das zusätzliche Koffein.

Hi Stephan! Vielen Dank für dein tolles Feedback! Es freut uns riesig, dass dir das Gel mit Koffein gefällt. Deine Hinweise zum Geschmack nehmen wir super gerne mit und arbeiten direkt daran, die Sorten noch weiter zu verbessern!
