Nrgy Gel 45 with Caffeine is designed for high-performance athletes who need a high carbohydrate intake, optimal hydration, and an extra mental plus physical boost — all 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. Additionally, it contains caffeine (65 or 130 mg) to sharpen focus and reduce fatigue.

CARBOHYDRATE RATIO

Nrgy Gel 45 with Caffeine 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.

CAFFEINE

Each gel contains 65 mg or 130 mg of caffeine (based on flavor). This will not only boost your physical performance, as you will feel less tired, but it will also increase your absorption of carbohydrates to improve your performance even more.

ELECTROLYTE MIX

It 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 these gels 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 with Caffeine 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.

When intensity spikes, this energy gel keeps your body pushing and your mind sharp.

Used by Elite 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.

Reviews in Other Languages

No tenéis la mas minina vergüenza con el cliente.

Tenéis la desfachatez de mandarme una encuesta para preguntar por un producto que no he recibido. Después de esperar me decís que no hay stock. Vergüenza debía daros. Me enviáis un mensaje de que mi pedido esta en camino y a la semana que hay un problema y no hay geles de cafeína. y me retrasáis casi otra semana el envío de lo que os da la gana. Habiendo recibido unos geles que no eran los que pedí. Y ahora me preguntáis.

Lamentamos profundamente lo ocurrido y comprendemos completamente su frustración. No hay excusa para lo sucedido, y le pedimos disculpas sinceras por los inconvenientes que esto le haya causado.
Nos gustaría enmendar esta situación y resolverla lo antes posible. Le agradeceríamos que nos escribiera a info@4endurance.es para que podamos revisar su caso y encontrar una solución que sea de su satisfacción.

Gel completo

Tiene un sabor como café con piruleta pero no es intenso, está bueno . No da problemas de estómago, no es empalagoso , la cantidad de CH es generosa , el único pero es la cantidad de cafeína igual si tuviera más se agradece , en algunos casos se necesita más .

Parfait, juste un bémol

Je commence par le bémol car les frais de livraison sont prohibitifs. Je commanderai beaucoup plus de produits si ce prix était contenu.
Pour l’analyse des gels que j’ai utilisés… ils sont géniaux.
Le packaging est plutôt pratique et résistant sans problème pour l’ouverture et la grande contenance permet de s’alimenter correctement.
Question goût je l’ai trouvé très agréable un peu sucré mais sans trop. Quant à l’énergie je n’ai pas été en dette au cours de mes très longues sorties (300 à 400km) sachant que l’apport de caféine se fait bien sentir, surtout lorsque l’on est habitué à en consommer lors des sorties en ultra cyclisme.
Bilan : avec un prix très compétitifs de ces gels 4Endurance frappe en grand coup et je recommande vivement des gels.
