The maltodextrin in SiS GO gels provides that carbohydrate, and the isotonic consistency means the gel doesn't need extra fluid drawn into the stomach to dilute it — so it empties quickly and is less likely to cause bloating. A common guideline is roughly one gel every 20–30 minutes during sustained effort, but follow your own fuelling plan.\u003c\/p\u003e\n\u003ch2\u003eNutrition \u0026amp; ingredients\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePer 60 ml sachet:\u003c\/strong\u003e ~87 kcal, ~22 g carbohydrate, 0 g fat, 0 g protein\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbohydrate source:\u003c\/strong\u003e maltodextrin (from maize)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOther ingredients:\u003c\/strong\u003e water, gelling agents (gellan gum, xanthan gum), acidity regulators (citric acid, sodium citrate), natural flavouring, preservatives (sodium benzoate, potassium sorbate), sweetener (acesulfame K), sodium chloride, antioxidant (ascorbic acid)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree from:\u003c\/strong\u003e gluten; suitable for vegans\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eComparison\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eGel\u003c\/th\u003e\n\u003cth\u003eCarbs\u003c\/th\u003e\n\u003cth\u003eFormat\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSiS GO Isotonic Gel (60 ml)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~22 g\u003c\/td\u003e\n\u003ctd\u003eIsotonic, no water needed\u003c\/td\u003e\n\u003ctd\u003eCaffeine-free, gentle on stomach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca href=\"\/products\/prozis-energy-gel-1-gel-25g\"\u003eProzis Energy Gel (25 g)\u003c\/a\u003e\u003c\/td\u003e\n\u003ctd\u003eConcentrated carb gel\u003c\/td\u003e\n\u003ctd\u003eSmaller, more concentrated sachet\u003c\/td\u003e\n\u003ctd\u003eCompact fuel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003ePairs well with\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/electrolytes-sport-gels\"\u003eElectrolytes \u0026amp; sport gels\u003c\/a\u003e — hydration and fuel for long sessions\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/drinks\"\u003eDrinks\u003c\/a\u003e — fluids to sip alongside your fuelling\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/sis\"\u003eSiS collection\u003c\/a\u003e — more Science in Sport endurance products\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eGreat alternative to\u003c\/h2\u003e\n\u003cp\u003eIf a thick, water-dependent energy gel upsets your stomach mid-effort, the SiS isotonic gel targets the same goal — fast carbohydrate during endurance exercise — in a format you can take on its own without bloating.\u003c\/p\u003e\n\u003ch2\u003eWhy buy from Top Nutrition \u0026amp; Fitness\u003c\/h2\u003e\n\u003cp\u003eTop Nutrition \u0026amp; Fitness is a premium Montreal sports-nutrition retailer serving Canada since July 2016.
