Science in Sport Isotonic Gels
Quick-hit fuel for endurance beasts. Each 60 ml pouch delivers 22 grams of fast-absorbing carbs (maltodextrin), around 90 calories, under 1 gram of sugar, and a hint of sodium—with no caffeine unless specifically labeled.
What makes them rock? These gels go down smooth—no extra water needed—so you skip bloating and the dreaded "sloshing" gut. The isotonic formula digests quickly, earning high marks from ultra runners and long-distance cyclists. They're vegan, gluten-free, nut-free, and certified by Informed-Sport, so no sketchy ingredients or doping concerns here.
Ideal for runners, cyclists, triathletes, and anyone pushing beyond 90-minute efforts. Gym-goers and HIIT junkies also love them for a quick, clean boost without heaviness.
Flavours like Orange, Lemon-Lime, Apple, Blackcurrant, and Tropical taste fresh and balanced—refreshing rather than overly sweet. Reviewers appreciate their authentic taste and gentle-on-the-tummy formulation. Note: The slightly larger pouch might require extra pocket space, but fans generally agree it's worth it.
Aim for 1–3 gels per hour (one every 20–30 minutes) to hit your carb targets during prolonged activities. No water chaser necessary.
Science in Sport GO Isotonic Gels are a sleek, gut-friendly choice for athletes needing steady, reliable fuel—without heaviness or crash. Whether you're pacing a marathon, crushing a century ride, or smashing intense training sessions, these gels fuel without fuss.
Add them to your stash if you want reliable carb power, easy digestion, and clean ingredients—all packed into a smooth, drinkable gel.
