Description
GlucoBooster™ Sport Energy Gel is a fast-acting glucose gel developed specifically for training, sport and active lifestyles. Each compact sachet provides rapidly available dextrose alongside magnesium, sodium and vitamin C, making it an easy source of carbohydrate energy before, during or immediately after exercise.
Each serving provides 11.3g of carbohydrate, including 10.6g of sugars, together with 42mg of magnesium and 20mg of vitamin C. Magnesium contributes to normal muscle function, electrolyte balance and energy-yielding metabolism, while vitamin C contributes to reducing tiredness and fatigue. The caffeine-free formula is particularly useful when you want straightforward carbohydrate fuel without adding a stimulant.
The blueberry-flavoured gel requires no mixing or preparation and can be consumed straight from the sachet, making it convenient for running, cycling, gym sessions, HYROX, hiking and other active pursuits. It is suitable for vegans. Important: this product contains rapidly available glucose and should be accounted for carefully by anyone managing diabetes or blood glucose levels. For hypo management rather than sport, GlucoBooster Glucose Gel is the relevant product. Food supplements should not replace a varied, balanced diet; see the wider wellness essentials range for broader everyday support.
Per 27ml serving: Energy 45.4kcal, Carbohydrates 11.3g, of which Sugars 10.6g, Magnesium 42mg, Sodium 171mg and Vitamin C 20mg.
Contains no caffeine.
How it works
Tear open the sachet and consume the gel directly before, during or immediately after physical activity.
The manufacturer recommends 1–3 sachets at a time, depending on your individual energy needs and activity.
The gel can be taken on its own, although drinking a little water alongside it may be preferable during exercise.
Store at room temperature and keep out of reach of young children.

Customer Reviews
Overall rating: 5.0 / 5 from 8 reviews.
The energy gel tasted a lot nicer than other gels I’ve tried but I really liked the glucose gel as it had a bit of a fizz to it. I really liked them, did what it said on the tin ,and tasted lovely ! I will definitely use some for my training and if there’s any left, I will use them on my half marathon in November and my she ultra in April!!
I have used them and I’ve been pretty impressed. They do the job entirely and in fact the first tempo run I used them on turned out to be my best run in a while. I used three of them on my long run yesterday and I find them easy to take, no problems on my stomach and that they provide what I need. I would be more than happy to promote these to our running club.
The members and coaches who used the gels used it before and during running, high intensity circuits, road biking, mountain biking. Everyone fed back that they loved the taste and found the texture good. One of our coaches usually has some gastro discomfort when using gels but reported that with yours she was absolutely fine! They found it easy to use and would use it again.
Really enjoyed this product! It tastes great and gave me the boost I needed to get through my first running event. I'd definitely buy it again and would happily recommend it .
The gels were good, texture and taste was great and most members noticed an improved performance.
Some guys used it for Hyrox training and some for half marathon and marathons. Think it definitely suits the Hyrox/Hybrid training better though.
I use these energy gels about five minutes before my weekly Parkrun, and they give me the extra boost I need to get round the course. They taste nice and I've found them much easier to digest than other energy gels I've tried. I'll definitely be using them again.
