A 60 ml sachet, squeezed open during a race or training. SiS GO Isotonic Energy Gel Lemon and Lime provides 22 grams of carbohydrates per sachet based on maltodextrin, without the need to drink water with it. The taste is a fresh citrus flavor, light and not too sweet. Gluten- and aspartame-free, suitable for vegans, certified by Informed Sport.
Isotonic is a chemical term that means a liquid has the same concentration as body fluids. An isotonic gel has the same concentration as body fluids, so you do not need to drink water with it. SiS introduced this principle in 2002 as the first in the world in an energy gel. In 2015, the product won the Queen's Award for Enterprise.
The energy source in this product is maltodextrin, derived from corn starch. Maltodextrin has a lower sweetness than regular sugar, which makes the gel less sticky and less intense in flavor. That is a conscious choice. During longer exercise, taste fatigue is a real problem and a gel that is too sweet works against you. Per 60 ml sachet you get 22 grams of carbohydrates, of which 0.6 grams are sugars. No significant fats or proteins.
Because the gel is isotonic, you do not need to drink water with it. That makes the gel usable at times when a bidon or water station is not available. You can open it during a sprint, halfway up a climb, or in the middle of a race without having to adjust your pace. Take 1 to 3 gels per hour to reach the recommended 60 to 90 grams of carbohydrates per hour. For a 3.5-hour marathon, that comes out to 10 to 12 gels in total.
All SiS GO gels are screened per production batch by Informed Sport for banned substances from the WADA list. Suitable for vegans and vegetarians, gluten- and aspartame-free. The aromas are of natural origin. No artificial colors in most flavors, except for the orange variant which contains beta-carotene.
The lemon and lime flavor is one of the fresher variants in the line, easy to combine with other flavors if you plan longer sessions with multiple gels per hour. The formula is identical in every flavor, only the aroma and any colorant differ.
SiS introduced this gel in 2002 as the world's first isotonic energy gel. In 2015, the product won the Queen's Award for Enterprise. Isotonic means that the concentration of the gel is the same as that of body fluids.
Most energy gels require you to drink water with them. That is not necessary with this one, because the gel is isotonic.
Aim for 60 to 90 grams of carbohydrates per hour during prolonged exercise. That's 3 gels per hour with intensive use. Each gel provides 22 grams of carbohydrates based on maltodextrin, of which 0.6 grams are sugars. Can be combined with other SiS products in your nutrition plan.

Isotonic means that the gel has the same osmolality as body fluids. Therefore, you do not need to drink water with it.
Tear open the top of the sachet and squeeze the contents directly into your mouth. Start taking it during exercise lasting longer than 45 to 60 minutes. Take 1 to 3 gels per hour, depending on intensity and duration. In cold conditions, your needs may be higher. You do not need to drink water with it, although you may.
No, that's the point. The isotonic formula makes an extra sip of water unnecessary. This is useful if you don't want to stop at a water station every time during a race or if you don't have a water bottle with you. Of course, you should drink normally throughout the day, but the gel itself works without extra fluid.
When exercising for more than an hour, the guideline is 60 to 90 grams of carbohydrates per hour. That's 3 gels per hour at the higher end. For a 3.5-hour marathon, you would therefore end up with 10 to 12 gels in total. If you combine them with other food, the number of gels will adjust accordingly.
Maltodextrin is a carbohydrate derived from corn starch. It has a lower sweetness compared to regular sugar, making the gel less sticky and less intensely sweet than sugar-based gels. It is widely used in sports energy gels.
Regular gels are often concentrated and hypertonic. The SiS GO gel is isotonic, so you don't need to drink water with it.
