Cyclic Dextrin 1kg, 33 Servings per tub.
Our Cyclic Dextrin is a market-leading top-shelf intra-workout carbohydrate supplement consisting of the hugely renowned highly branched cluster dextrin. Cluster Dextrin is the champion of fast-digesting carbohydrates, making it an essential and highly effective intra-workout supplement to provide your muscles with almost instant fuel. Highly branched cluster dextrin has been scientifically proven to digest and work more efficiently and effectively than any other carbohydrate source on the market.
Created from the trademarked Cluster Dextrin it is far superior to a stand alone maltodextrin.
Mix one scoop with 300ml of water and consume before, during or after a workout. It is recommended to consume intra-workout for instant energy. Who is it for? Everyone. Quite simply, whether you’re a cyclist, bodybuilder, functional athlete or martial artist, this product will take your training to the next level, allowing you to push harder and for longer.
For clarification, Cyclic Dextrin goes by three primary names including; Highly Branched Cyclic Dextrin® (HBCD), Cluster Dextrin®, and Cyclic Dextrin®. They’re all referring to the same thing. In this product and our blogs we use the name Cyclic Dextrin. Cyclic Dextrin is a registered trademarked ingredient produced by Glico Nutrition.
“An Endurance Study with Cluster Dextrin demonstrated a 50% increase to fatigue.*Cluster Dextrin improved Gastric Emptying Time compared in Glucose & Dextrin based solutions.*Note; FDA has not evaluated the statement above.Cluster Dextrin is not intended to diagnose, cure or prevent any disease.” –Glico.
Cluster Dextrin is manufactured by applying an enzyme called a branching enzyme to cornstarch . The branching enzyme works on the joint of the cluster structure of amylopectin and degrades it by cyclization. Thus, Cluster Dextrin is considered to maintain the cluster structure, which is the basic structural unit of amylopectin, nearly as it is. –Glico.
Usually, in the case of beverages with electrolytes only, 280 mOsm (same osmotic pressure as bodily fluid) is absorbed quickest. However, our research revealed that gastric emptying when the beverages contain carbohydrates, with a low osmotic pressure beverage of approximately 150 mOsm, is the shortest in proportion to the osmotic pressure of the beverage and gastric emptying (transfer time from stomach to intestine)*1).
That is, if low molecular weight carbohydrates such as glucose are used, osmotic pressure becomes higher even if the concentration is the same (620 mOsm in 10% solution), and only leads to preparation of slow gastric emptying beverages.
On the other hand, if approximately 2500-fold higher average molecular weight Cluster Dextrin compared to glucose is used, osmotic pressure is hardly affected and hypotonic sports drinks can be readily designed, even though electrolytes, vitamins, and amino acids, which are essential for sports drinks, are combined.

We confirmed that the endurance increasing effect can be obtained by consuming a beverage containing Cluster Dextrin !
Beverages combining Cluster Dextrin are characterized to contain highly concentrated carbohydrate and fast gastric empting. Therefore, the carbohydrate energy, moisture, and electrolytes consumed during exercise can be re-supplied promptly. We confirmed that administration of Cluster Dextrin to mice significantly increased the swimming time (=endurance) in endurance swimming compared to administration of water and glucose solution*2).
Moreover, we investigated the critical swimming time of top swimmers swimming in a flowing water pool after taking each beverage shown in Figure. As a result, it was revealed that swimming time is significantly extended when Cluster Dextrin containing beverage is consumed compared to the cases with other beverages.

I’ve been using the CYCLIC DEXTRIN in Strawberry & Lime flavour, and it has quickly become my go-to for fueling my workouts. The taste is light and refreshing, with the perfect balance of strawberry sweetness and a hint of lime. It mixes easily and doesn’t feel heavy on the stomach, making it great for both pre-workout and during exercise.
What I love most is how it provides a steady release of energy, keeping me going through long training sessions without any crashes. Highly recommended for anyone looking to enhance endurance and performance!
k ashcroft –
another repeat order – this stuff works, plenty of sustainable energy
Lewis Hamilton –
Using with EAA’s. Training six days a week for my coming up PTI course and training BJJ too. Keeps me fuelled up and lets me train for much longer without getting burned out. A must when it comes to those harder sesh’s.
CARL BARNETT –
This supplement is an absolute must for any athlete to be drinking during their workout/sport. Not only taste insane the it’s a must for recovery and energy during your workout. Well done Combat Fuel
Sean R –
Bought this alongside the ‘EAA’S + ELECTROLYTES’ and use it in conjunction with one another.
The Caribbean and Spinegrapple flavours mixed together are freakin’ delicious! Used intra-workout for my more tougher sessions, they help maintain my intensity and prevent me feeling completely drained post workout.
Yet again an outstanding product and service from the CF team
John C. –
I actually use this for fuelling during cycling as I do long distance rides. This has really helped me maintain my energy levels on rides.
Jolly G. –
Took 1 bottle water and 1 bottle of this for a marathon. It really helped keep those endurance levels where i needed them.
Simon T. –
Great taste, easy mix, does what it says on the tin!
Nikki B. –
Absolutely love this product
Jonny M. –
Awesome
David H. –
Quite possibly the nicest powder on the Market! Smooth and great flavour, no gut bombs and gives you the push you need before and during a workout! Excellent product and great company! Can not recommend this enough!!!!!
Ian B. –
Havnt used this before but been reading about it, great product used it as instructed. Had it during 15mile jog/walk gave lots of much needed energy.
Jay H. –
Fantastic service, great supplement!
Sean S. –
Taste really good on its own but if you mix it with passion fruit water, even better
Chris I. –
Having taken supplements throughout the last 9 or 10 years, I was dubious buying something I’d not used before. Quick chat with the gents at Combat Fuel, a read of the info and now I’ll not train without it, haha. A must buy
Nikki B. –
Love, love ,love this product. Great taste
Fiona M. –
After w quick chat with the guys they suggested this would be beneficial for me. It’s been brilliant, tastes great and really gives me an interesting-workout boost.
Billy B. –
Currently training for the marines and live this stuff keeps u going through all my training needs
Mick H. –
As an endurance/ultra marathon runner fueling the body is so important. I’ve tried all the “runner specific” brands that specialise in this type of fueling and I’ve always been left disappointed. Combat fuel have genuinely hit the nail on the head here – tastes great, no bad effects on the stomach, no wierd caffeine jitters and it delivers plenty of carbs and energy. I use this as my only (non food) energy source, no gels or caffeine chews etc. 10/10.
Ryan M. –
Great product! Adds value to my training and tastes great
Rikki W. –
Never do a review on workout powders or stuff like this, but used the Combat Fuel cyclic dextrin before a 24k tab, and well I would normally get really tired but after getting home I was not tired or feeling drained at all.
Highly recommended for any kind of physical exercise, and when you need that something extra, more than pushing yourself that little extra.
Morgan B. –
Tastes amazing, it gives you that kick of energy when you really need it
Can’t fault it
10/10
John f. –
Stacked with EEA’s this is great for my boxing training it keeps my going
kevin a. –
Good supplement, works well. Good taste [great colour mixed], easy to mix.
Definitely makes a difference to my endurance when using for the gym or running.
stephen k. –
i was completely new to cyclic dextrine and a few guys recomended i try combat fuel, was a brilliant decision…gives you some great sustaineable energy without making your blood sugar shoot through the roof like the gels that cost a fortune etc
John f. –
Use this stack for boxing training it keeps me going far better than just water I take mist before about 15 mins then sip rest intra training. With the the amount of gravy i shed it’s important to replace the lost minerals
andrew m. –
Great tasting product love this flavour across all of combat fuel lines could drink it all day long
Steve M. –
Perfect to use during long workouts. Keeps the energy up.
