What "isotonic" means in practice
Isotonic is a scientific term that indicates a liquid has the same concentration as the cells in your body. For an energy gel, this means the stomach does not need to draw in extra fluid to dilute the gel before passing it through. This is what happens with most classic gels, and sometimes causes a feeling of bloating. With an isotonic gel, the product leaves the stomach faster and carbohydrates are available more quickly. SiS introduced this principle in 2002, a world first for an energy gel. In 2015, the product won the Queen's Award for Enterprise.
22 grams of carbohydrates from maltodextrin
The energy source of this product is maltodextrin, derived from corn starch. Maltodextrin has a lower sweetening power than ordinary sugar, which makes the gel less sticky and less intense in taste. This is a deliberate choice. During prolonged efforts, taste fatigue is a real problem and a too-sweet gel then works against you. Per 60ml sachet, you get 22 grams of carbohydrates with only 0.6 grams of sugar. No significant amounts of fat or protein.
No water needed, and convenient
Since the gel is isotonic, you don't need to drink water with it. This makes the gel usable when a bottle or aid station is not within reach. You can open it during a sprint, in the middle of a climb, or during a race without having to adapt your pace. Take 1 to 3 gels per hour to reach the recommended 60 to 90 grams of carbohydrates per hour. For a 3h30 marathon, this represents 10 to 12 gels in total.
Informed Sport certified, gluten-free and aspartame-free
All SiS GO gels are batch-tested by Informed Sport for prohibited substances on the WADA list. Suitable for vegans and vegetarians, gluten-free and aspartame-free. Flavours are of natural origin. No artificial colours in most flavours, with the exception of the orange variant which contains beta-carotene.
The lemon and lime flavour is one of the most refreshing variants in the range, easy to combine with other flavours if you plan longer sessions with multiple gels per hour. The formula is identical in each flavour; only the aroma and any colouring differ.
