Carbs Fuel Original 25g Energy Gel

The only differences are the size and nutritional contents of the energy gels.

We use the exact same formulation as the Original 50g gel, but in a smaller packet and filled with half the volume!

If you're looking to consume high-carb and you're focused on getting the best value in energy gels, you should get the Original 50g Energy Gel.

We made the Original 25g Energy Gel for athletes in a few scenarios:

1. For shorter activities where 50 grams of carbohydrates or 200 calories doesn't feel necessary, but bringing fuel on-board is still important.
2. For athletes with more limited pocket space. We found many runners in particular struggle with large gel packets; the Original 25g Energy Gel is smaller and more compact.
3. For athletes looking for further precision in their hourly carbohydrate intake; this smaller serving, when mixed with our 50g energy gels, can help achieve specific fueling goals.
4. For athletes newer to fueling, who may be intimidated by consuming 50g of carbs and 200 calories in one single packet. The Original 25g Energy Gel is the perfect starting point to build up your fueling strategy.

The original flavor is bright, sweet, and slightly citrusy; it is neutral enough for athletes to enjoy consuming in hour 1 and hour 6 of their endurance activity.

We may launch products of other flavor variations in the future, but we think our original flavor is exceptional. We are focused on delivering a simple and effective product that helps more athletes effectively fuel their sport.

The Carbs Fuel energy gel has a low viscosity, or thin consistency, thanks to our unique carbohydrate sources and decision to avoid gelling agents.

We dont use gelling agents like Gellan Gum, Xanthan Gum, or Pectin because we wanted to eliminate the use of any ingredient which could cause stomach problems.

Plus, if it doesn't help your endurance performance, why would we?

Our gels are naturally a great consistency thanks to the carbohydrate volume.

The Carbs Fuel energy gel is a blend of three carbohydrate sources to achieve a 2:1 glucose-to-fructose ratio. The three sources of carbohydrates are maltodextrin, sucrose, and fructose.

Current research suggests the optimal ratio of glucose and fructose, for maximal carbohydrate uptake and minimal risk of GI issues, is between 2:1 to 1:0.8 glucose-to-fructose ratio. As of 2025, current research suggests the 1:0.8 ratio to be the most optimal, however, proper fueling is not black and white. There are numerous other factors to consider which may affect the athlete. Some example factors could be the product's palatability, or the athlete's sensitivities to ingredients like preservatives, and gelling agents. Carbs Fuel thoughtfully selected a 2:1 ratio, instead of a 1:0.8 ratio, for a couple reasons.

1. Some athletes have a greater sensitivity to fructose, when compared to glucose; we believe the 2:1 ratio will allow a wider breadth of athletes to fuel their sport.
2. A key aspect to helping more athletes fuel effectively is ensuring it is a product that is palatable and easy to consume. We found the higher fructose concentration in the 1:0.8 ratio created a sweetness profile that was less palatable during our product development. A proper fueling strategy only works if the athlete is excited and able to continue consuming their energy gels late into their activity.

The Carbs Fuel energy gel has a best-by date 24 months past the date of manufacturing. We've achieved a lengthy shelf life by achieving a balance between pH and water activity.
