Pros & Cons
Pros & Cons
- The SiS gels are easily and quickly absorbed by the body due to their isotonic concentration.
- The SiS Go Isotonic Energy Gels can be taken without water or a sports drink. Ideal during intense exercise, when it's difficult to drink large amounts of water.
- Due to their light concentration, this gel is also suitable for cyclists with a sensitive stomach and intestines.
- Easy to tear open, so this energy gel is ideal to consume on the go.
- Energy gels are less suitable for meeting long-term energy demands due their high absorption rate.
- Texture can vary between gels, but fortunately this isn't an indication that the gel has expired.
- Please note: the gels have a shelf life until 30-04-2026!

The SiS Go Isotonic Energy Gel 7-pack is an ideal package for cyclists who want to try various gel flavours.
The SiS Isotonic Energy Gel is a flavourful energy gel rich in energy. With its unique formula, SiS has created an easily digestible gel. The SiS Go Isotonic Energy Gel was the world's first isotonic energy gel. The human body quickly and easily absorbs SiS gels due to their isotonic concentration. This provides the body with a rapid energy boost. The SiS Go gels are also exceptionally suited for consuming during exercise at fast heart rates, when it's harder to digest food.
Another upside is that you can consume the SiS Go Isotonic Energy Gels without any water or sports drinks. This makes the gels ideal during intense exertion when it's hard to drink large quantities of water. Due to the isotonic concentration, this gel is also suited for cyclists with a sensitive digestive tract.
It's for good reason that the SiS Go Isotonic Energy Gels were crowned the winner of the Queens Award: a prize for exceptional innovation. The Go Isotonic Energy Gels are often prominently present at pro sporting events and are consumed daily by thousands of endurance athletes all over the whole world.

Recommended Usage: Ideal for consumption during exercise. Tear the top off the sachet and drink! You can consume these gels without drinking water.
Recommended dosage: The most common cause of fatigue is the depletion of carbohydrate reserves during exercise. Replenishing carbohydrates before and during exertion can improve (cycling) performance. If the exertion lasts longer than 90 minutes, it's recommended to consume additional carbohydrates. It's recommended to take 1 to 3 energy gels per hour. Or combine the energy gels with other sports nutrition until an intake of 60 grams of carbohydrates per hour. A common strategy is to consume energy gels during the more intensive phases of exercise. Digesting energy gels requires less circulation compared to other sports nutrition.
Warning: A nutritional supplement is not a substitute for a varied diet. In addition to physical exercise, it's important to follow a varied and balanced diet and to lead a healthy lifestyle. Don't exceed the recommended dosage. If you're following a special diet or use medicine, it's always safe to ask your doctor for advice. Don't use this product structurally and long-term without medical advice.
