Science In Sport GO Isotonic Energy Gel
Fast-acting energy gels built for endurance athletes — runners, cyclists, triathletes, swimmers, and team-sport players — who need a quick, easily digestible carbohydrate hit during exercise without the bloat or stomach distress that comes with most syrupy, non-isotonic competitor gels. Ideal for race day, long training sessions, and any effort sustained beyond an hour where carb depletion starts to impact pace.
What separates this from the rest of the gel category comes down to the genuinely isotonic formulation — and the credentials behind it. The GO Energy Isotonic Gel was the world's first true isotonic energy gel and a winner of the Queen's Award for Enterprise. Each 60ml sachet delivers 22g of fast-release carbohydrate at the same osmotic concentration as your body's fluids, which means it can be absorbed and converted to energy without first needing to be diluted with water in the stomach. That's the practical edge: most non-isotonic gels demand a chase of 100–200ml of water with every serving to avoid stomach distress, which isn't always realistic mid-race or mid-pool. The light, compact packaging fits in jersey pockets, race belts, swim deck bags, and trisuit pouches — replacing the bulk of sports bottles when you need to travel light.
Science In Sport is a UK-based brand publicly listed on the London Stock Exchange (AIM: SIS) and manufactured to GMP standards. The GO Isotonic Energy Gel is Informed-Sport registered with batch-level testing for WADA-banned substances, making it a credible choice for tested-pool athletes. The brand is the official supplier to multiple WorldTour cycling teams, Olympic federations, and Premier League clubs.
- 22g of fast-release carbohydrate per gel in a genuinely isotonic format — no water chase needed
- The world's first isotonic energy gel and Queen's Award for Enterprise winner — the original benchmark in the category
- Excellent as energy gels for swimmers during pool deck breaks and as energy gels for cycling in jersey pockets — practical packaging for any sport
- Vegan, vegetarian, gluten-free, lactose-free, nut-free, soya-free — the most allergen-friendly choice among the best energy gels for endurance athletes
- Informed-Sport registered — credible for tested-pool athletes and used by professional cycling teams
Pair it with electrolyte powder or carb snacks from our energy and hydration range to hit the 60–90g carb-per-hour target on long sessions.
