Nrgy Gel 45 is designed for athletes with high energy demands who need a gel that reliably delivers carbohydrates without causing digestive issues.

1:0.8 CARBOHYDRATE RATIO

Nrgy Gel 45 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 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
  • Prevents muscle cramps
  • Contains key electrolytes to support hydration
  • Informed Sport certified
  • Vegan, gluten-free, and no artificial sweeteners

Consume 1–2 gels per hour, depending on your carbohydrate needs and personal tolerance. You can also combine Nrgy Gel 45 with energy drinks or bars to help meet your hourly carbohydrate targets.

Who should use Nrgy Gel 45?
Nrgy Gel 45 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 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?
Most athletes use one to two Nrgy Gels 45 per hour, depending on exercise intensity, duration, and overall fueling strategy. Total carbohydrate intake should be adjusted based on individual tolerance and performance goals.

Should I take Nrgy Gel 45 with water?
Yes. Taking Nrgy Gels 45 with water supports digestion and carbohydrate absorption, especially at higher intake levels.

Can Nrgy Gel 45 be combined with other fueling products?
Yes. Nrgy Gel 45 can be used alongside other fueling gels, drinks, and bars. To reduce the risk of gastrointestinal disturbances, we recommend using Nrgy Gels 45 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 suitable for hot conditions or high-sweat sessions?
Yes. Nrgy Gel 45 with electrolytes is especially useful in warmer conditions or during sessions with higher sweat rates, where electrolyte losses are greater.

Can Nrgy Gel 45 cause stomach issues?
Nrgy Gel 45 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 vegan and gluten-free?
Nrgy Gel 45 is suitable for a vegan diet and does not contain gluten.

Why does the nutrition label say that Nrgy Gel 45 contains 22 g of sugar?
Because not all carbohydrates in Nrgy Gel 45 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 contain caffeine?
Nrgy Gel 45 is available in two versions: with caffeine and without caffeine. The caffeine-containing version has a red top and clearly states that it contains caffeine on the packaging.

Does Nrgy Gel 45 contain electrolytes?
Nrgy Gel 45 is available in two versions: with electrolytes and electrolyte-free. The electrolyte-free version features a light blue top and clearly states “electrolyte-free” on the packaging. The version with electrolytes has a black top. There is also a version of Nrgy Gel 45 which contains both caffeine and electrolytes. It features a red top. 

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. 

What makes Nrgy Gel 45 different from other energy gels?
Nrgy Gel 45 delivers a higher carbohydrate dose than most gels, providing 45 grams of carbohydrates per serving in a scientifically validated 1:0.8 glucose–fructose ratio. This allows for greater carbohydrate absorption with reduced gastrointestinal stress. In addition, Nrgy Gel 45 is available in multiple versions — with or without caffeine and with or without electrolytes — giving athletes precise control over their fueling and hydration strategy.

Does Nrgy Gel 45 come in other amounts?
Yes. Nrgy Gel is also available in a lower-dose version that provides 22.5 grams of carbohydrates and does not contain electrolytes. This option is useful for athletes who prefer smaller, more frequent fueling doses or who want to fine-tune carbohydrate intake independently of electrolyte intake.

Does Nrgy Gel 45 contain any banned substances?
No. Nrgy Gel 45 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?
Nrgy Gel 45 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.

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.
