Maurten Gel 100 and GU Original Energy Gel differ in texture, flavor choices and the amount of carbohydrate in a packet. Start with the format you are willing to try during training, then compare the cost of repeating it. Neither brand’s product description tells you how it will feel in your stomach.

Quick answer: choose a packet before choosing a box
Consider Gel 100 if you want to try a firmer gel without added flavoring. Consider GU Original if choosing among flavors matters to you. Read the exact caffeine label in either case. Begin with a small quantity instead of committing to a bulk order on the strength of a brand name.
| Decision | Maurten Gel 100 | GU Original Energy Gel |
|---|---|---|
| Carbohydrate per packet | 25 g on Maurten’s product page | GU lists 21–23 g depending on the option; inspect the flavor label |
| Texture and flavor | Maurten describes a firmer hydrogel with no added flavors | GU describes a smooth gel and offers named flavors |
| Caffeine | Gel 100 and Gel 100 Caf 100 are separate products | Caffeinated and caffeine-free options share the product family |
| Water | Maurten says water is not needed to help swallow its gel; that does not remove your need for fluids | GU’s directions say to take gels with a few sips of water |
| Purchase comparison | Check the box count and product name | Check the box count, flavors and caffeine mix |
Make the price comparison fair
Divide the delivered box price by the number of packets, then compare the cost of the amount you actually plan to carry. Two boxes with different packet counts are not a like-for-like comparison. Include delivery charges and avoid buying more than you can use within the printed date. Prices, sellers and stock vary; the links below do not establish today’s delivered price.
To compare cost per 25 g of carbohydrate, divide the packet price by its labeled carbohydrate grams and multiply by 25. This is purchase arithmetic, not a recommendation for how much to consume.
Maurten Gel 100
Read the product name carefully: this comparison concerns Gel 100, not Gel 160 or Gel 100 Caf 100. The packet label is the final check for ingredients and serving information.

GU Original Energy Gel
Choose the flavor and caffeine option before comparing pack prices. GU Original, GU Liquid Energy and GU Roctane are distinct products; do not treat their labels as interchangeable.

What to record during a trial
Write down the exact product, flavor, amount consumed, water taken, run duration and any discomfort. Changing the gel, breakfast and drink together makes the result harder to interpret. One comfortable trial does not establish how repeated servings will feel on a different day. This guide does not provide an individualized fueling or hydration prescription.
If you already tolerate an affordable product, there is no need to change solely because another brand appears at a race. If neither texture suits you, compare a different format before ordering another large box. Check ingredients and allergen information on the package; this page cannot assess individual dietary or medical needs.
Other formats to compare
These are separate options, not equivalent substitutes for the two gels above. Inspect each exact product’s ingredients, carbohydrate amount, caffeine label and date before choosing: Huma Chia Energy Gel, Spring Energy Race Pack, and Honey Stinger Energy Gel. Retailer titles can combine pack sizes and variants; verify the selection before paying.

Is Maurten better than GU?
The label and format differences do not establish a universal winner. Compare the exact packet, cost and your own experience before committing to a box.
Does a mixed GU box mean caffeine-free?
No. Check the exact assortment and each packet. GU lists both caffeinated and caffeine-free options.
