Dual-source carbohydrates = higher energy delivery
Your body absorbs carbohydrates through different transport systems in the gut:
Glucose → absorbed via SGLT1 transporters
Fructose → absorbed via GLUT5 transporters
Most traditional fuels rely on just one pathway (usually glucose), which limits how much energy you can absorb per hour.
By combining glucose + fructose (plus real honey), you:
Use multiple transport pathways simultaneously
Increase total carbohydrate absorption
Deliver more usable energy per hour
👉 This is why dual-carb systems are used in high-performance endurance fueling.
Improved GI comfort under load
One of the biggest performance limiters isn’t fitness — it’s gut tolerance.
When you overload a single carb pathway:
Carbs sit in the gut
Water is pulled into the intestine
Result = bloating, cramping, discomfort
By using dual carbohydrates, you:
Reduce pressure on a single absorption pathway
Improve gastric emptying
Lower the risk of GI distress
Meaning you can fuel consistently — without your stomach shutting you down.
Every Square is Handmade.
Format matters more than people think
Fuel only works if you can actually take it.
During high intensity:
Blood flow to the gut is reduced
Chewing becomes harder
Overly sweet or sticky fuels become difficult to tolerate
That’s why texture and usability are critical.
The soft nougat format:
Requires minimal chewing
Is easy to consume while moving
Reduces the “fuel resistance” athletes often experience
👉 This leads to more consistent fueling — which is what actually drives performance.
Customer Reviews
Overall rating: 4.7 / 5 from 27 reviews.
Loved the fact that I can run with one product and have everything I need
Regular marathon runner here. Absolutely love these. Bought them for my CTM 26 training block. Easy to digest without feeling bloated or sick afterwards while running and a sustainable amount of energy is given through each square. Used them as well on race day, didn't hit the wall once, they kept me well fueled. Will keep buying these for all my races.
Been running for a while now, and this is probably the best on the market for any long run. It really sustains you and gives you that energy when needed.
One word, ✨ Satisfying ✨!
I bought like 5 packets after tasting them for the first time at The Burnt Out F 100. They are effective and tastes simply amazing. Great product. 5 🌟
With my first Hyrox event coming up, I was searching and searching for the perfect way to refuel during the race. I came across the 13 Energy Squares. I mean, Carbohydrates AND electrolytes in one ? It’s a no brainier really. I put it to test in my simulation today and I’m so happy and confident with my choice ! Bonus is that it tastes so good !
It provides me with non-stop energy and i dont get tired like i used to before. This is an amazing product .
Exactly what I was looking for. Tastiest nougat around and excellent alternative to gels. This will be added to my Comrades fuelling!
Great product!
Really enjoying these. They come in a good "bit" size and taste really good as well.
Tasty, easy to unwrap during the ride.
The product hardens in cold weather. B careful not 2 bite in cold . Broke a tooth
This is a really great product. Love the convenience of it and the fact that it has the same, if not more nutrients than traditional gels. This is my new go to! I think the 3 packs I ordered will be done soon
I am very happy with the results!!!
Love this product! Tried it for every 6k of my 30k long run and it was an amazing gel replacement. Sits better than any gel I’ve tried and the salty rice paper tastes so good in complement to the honey nougat. Thank you for the awesome product!
Tastes amazing
My new fuel bestie. Taste, packaging and texture are all 10/10! Absolutely love this!
I might be a little too obsessed, these are so delicious
Great. Soft. Easy to chew and swallow.
I used the energy square on a long run & it was so easy - to open, to eat & settle whilst being able to keep moving. Love the size, the branding aesthetic & Ofcourse, the taste!
The energy squares are out of this world good tasting. I’m still playing around with the cyclic dextrin to get the perfect ratio when mixed with malto dextrine for bicycle racing.
Love love looooove! These have everything you need and nothing you don't. Light on the stomach, heavy on energy.
I am currently training for my first full Ironman in 2 weeks and needed something ‘whole’ to eat on the bike to reduce the amount of gels I bought this to try out and honestly WOW!!! You guys did it again. This is amazing. It’s perfect for that long bike snacks to reduce the gels and take something solid as well. And it’s easy on the gut.
Great taste, the texture probably needs a bit of getting used to. These are NOT a cold weather option! The bars get too hard to bite through. Maybe dividing the bars in half would be a solution.
Just personal preference- I found the bar too hard. This made it difficult to chew and swallow while running.
The bars was melted and was squashed could not even remove some of them from the wrapper that was melted stuck and this was from the same day as receiving them out of the box. The taste was okay but it was hard chewing them. At the moment fastbar from racefood is match better. Hope you can sort the melting problem because it screwed up a good bar. Regards
