Maurten Hydrogel review summary: It’s a 40 g energy gel with 100 calories and 25 g of carbohydrates at 1:0.8 glucose to fructose ratio as the main sources of sugar. The carbohydrates are encapsulated in a hydrogel, which can bypass the stomach to the intestines, where they can be absorbed faster and without causing gastrointestinal distress. The gel also provides 35 mg of sodium and 21.6 mg of calcium. It’s mildly sweet with a unique consistency similar to jello that’s not quite completely set.


With GOATs such as Eliud Kipchoge and Kilian Jornet representing Maurten, the Swedish energy gel brand, with its sleek black and white packaging, is making waves in the endurance sports scene.

This Maurten Hydrogel review will take a closer look at some of the company’s scientific claims, and I will share my personal experiences using the Gel100 and Caf100 for a recent race and long training runs.


Scientific claims – what is Maurten Hydrogel?

Company founder Mårten Fryknäs, an avid triathlete, set out to solve gastrointestinal distress caused by sports fueling products such as drink mixes and energy gels.

With experience in pharmaceutical research, Fryknäs knew that hydrogels are effective in delivering drugs into patients, so in theory, this technology should also work for replenishing carbohydrates during exercise.

According to Maurten, carbohydrates encapsulated in a hydrogel can bypass the stomach to the intestines, where they can be absorbed faster and without causing gastrointestinal distress.

Unlike traditional energy gels, which are essentially a syrupy mix of water and carbohydrates, the Gel100 is a “biopolymer matrix” with a 0.8:1 ratio of fructose and glucose, allowing an athlete to take up to 100 g of carbohydrates an hour, the company claims.

What does this all mean? Carbohydrates are the primary energy source, meaning the more you can absorb without upsetting your stomach, the better. Maurten recommends taking four packs of Gel100 (25 g of carbohydrates per pack) compared with the generally accepted practice of two to three packs per hour for other gels.


What are the ingredients of Maurten Hydrogel? Oh so simple

Calcium Carbonate
Gluconic acid
Sodium Alginate

Most energy gels in the market consist of at least ten to twenty ingredients with added flavoring, preservatives, and other nutrients such as amino acids. Looking at Maurten’s six listed ingredients, it’s pretty much just sugar, salt, and thickeners.

The company calls its energy gels “clean.” While I understand that they are trying to communicate the simplicity of the ingredients, when I think of clean, it’s natural foods with minimal processing. So, I personally would like to push back on using the word.

The caffeinated version, Caf100, is based on the same ingredients but contains 100 mg of caffeine. That’s the same amount of caffeine as one big cup of Joe.


Nutritional facts

1 x 40 g sachet provides the following:

  • 100 calories
  • Carbohydrate 25 g
  • Fat 0 g
  • Protein 0 g
  • Sodium 35 mg
  • Calcium 21.6 mg

As I said, sugar and salt. Two important things the body needs to kick ass.


What are the taste and consistency of Maurten Hydrogel?

I’m firmly entrenched in the “all-gels-taste-bad” camp. Despite trying many brands and countless flavors over the years, I’ve yet to find an energy gel that can be considered tasty.

Some are tolerable, but when you get to the third, fourth, or fifth pack, your taste buds and brain inevitably get sweetness fatigue. So spare me the additives and flavoring, and just give me the essentials. I’m not eating energy gels for the great taste anyways.

That’s why in the flavor category, I give Maurten two thumbs up. Not that its energy gels taste great, but the company has managed to tame the issue of sweetness overload.

I agree with Maurten’s product philosophy of providing what you need with as little nonsense as possible. The simplified ingredients deliver only a mild sweetness. Combined with the hydrogel’s unique texture (like not completely set jello), I have to say that the Gel100 is easy to stomach with almost no aftertaste.

I find the texture quite “fun” and a nice change of pace from the more common syrupy options.


Packaging – easy enough to tear and consume

The sachet is relatively standard – compact enough for most fuel-carrying gears and easy to tear open. I have no issue consuming the energy gels on the move (running and cycling). Initially, I thought the sachet was packed quite full. I was worried about “gel explosion” on longer trail runs when I had to stuff them in my hydration vest with other gears. But no such issues occurred.

A side note: I think the black and white design looks exceptionally cool and goes well with the simple ingredient, no-nonsense concept.


Does Maurten Hydrogel work? – 60km road ultra field test

I’ve used Maurten energy gels on several training runs that were 3+ hours. However, the primary field test for this review was a 60km road ultramarathon with roughly 2000m of elevation. It took 5 hours and 34 minutes.

For races like that, my strategy is to maintain a consistent, moderate effort throughout and definitely avoid red lining at any point.

I brought six Gel100s and one Caf100s and had them in a compression running belt.

I had a hearty breakfast of honey and overnight oats an hour and a half before the start, so I was topped up and didn’t eat my first gel until an hour into the race.

Afterward, I ate one every 30-40 minutes and stuck to sports drinks and water at the aid stations. It was not an overly long race, so I didn’t need solid foods. I saved the Caf100 for the halfway turnaround for an extra boost.

Some takeaways:

  1. I had no stomach issues and didn’t have that “yuck, I don’t want to eat another gel?” moment during the race.
  2. As mentioned earlier in the article, I appreciated the lack of sweet aftertaste. I could almost eat the gel without water.
  3. In terms of performance, there was no noticeable difference compared with other gels. But it did its job, providing consistent energy without bad taste and stomach issues.
  4. However, in past ultras, instead of gels that I had brought along, I often went with fruits or chips at aid stations because I couldn’t imagine eating another gel. Maurten’s mild flavor allowed me to stick with gels as the primary fuel. I believe this is a plus for performance since solid foods are harder and slower to digest and metabolize.
  5. Prices for Maurten products are on the higher end. It’s USD 43.5 for a box of 12 Gel100 and USD 50 for a box of Caf100.



Moving forward, I think Maurten will be a part of my fueling arsenal, along with other brands, just to mix up the flavors on long races. I also don’t want to rely exclusively on a more expensive option when cheaper ones I’ve used before can do the job. Due to the price, Maurten will be strictly a race fuel for me. Perhaps even save Maurten energy gels for the second half of the race when my stomach tends to be more sensitive.

Maurten made energy gels “more tasteless” instead of adding more flavoring in an attempt to solve the unsolvable gel flavor issue. In a roundabout way, the company sort of did provide a good solution. Overall, I believe in and enjoy this simplistic, no-nonsense approach.
