Science in Sport 60 ml Energy Gel Variety - Isotonic Endurance Boost

In this review of the Science in Sport 60 ml Energy Gel Variety pack, the bottom line is simple: these gels are aimed at endurance athletes who want rapid carbohydrate delivery without needing water. The reviewer found the gels especially useful for long training sessions and races where avoiding bloating and maintaining steady energy are priorities. The pack format of seven 60 ml sachets makes them convenient for a long run, race day or multi-hour ride, and the truly isotonic formulation is the single biggest reason to buy for athletes who value quick absorption and minimal stomach upset.

Key Features

• Isotonic formulation: Delivers carbohydrates in a truly isotonic form so the gel can be consumed without water for faster uptake and less gastrointestinal discomfort.
• 22 g carbohydrate per serving: Supplies a compact 22 g of carbs and 87 kcal to help maintain energy during sustained exercise.
• Low sugar and maltodextrin blend: Uses maltodextrin and added sodium to support electrolyte balance and steady carbohydrate release.
• Trusted by elites: Backed by sponsorship of professional cycling programs, indicating formulation used by competitive athletes.
• Gluten free: Suitable for athletes avoiding gluten while still needing a concentrated carbohydrate source on the move.

Who It's For

These gels are best for runners, cyclists and triathletes doing long sessions or events who want a quick, easily digestible carbohydrate top-up without carrying extra water. The isotonic format is especially useful for those who experience bloating when drinking while racing or training.

Athletes who prefer chewable solids, whole-food fuel or very sweet, flavoured gels may want to sample a single sachet before committing to a variety pack; some users report mixed opinions on taste and texture, so sensitivity to flavour matters.
