Pros & Cons
Pros & Cons
- Due to their isotonic concentration, the SiS gels are quickly and easily absorbed by the body.
- The SiS Go Isotonic Energy Gels can be taken without water or a sports drink. This makes them ideal during high-intensity workouts when it is difficult to drink large amounts of water.
- The low concentration makes this gel suitable for cyclists with a sensitive digestive tract.
- The tear-off strip makes the gel easy to consume while you're cycling.
- Because of the rapid absorption this gel is less suitable for efforts which require long-burning fuel.
- Texture can vary between gels, but fortunately this isn't an indication that the gel has expired.

The SiS Isotonic Energy Gel is a tasty gel that is rich in energy. With a 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 absorbs it quickly and easily due to the isotonic concentration, and gets a rapid energy boost. The SiS Go gels are, therefore, exceptionally suited for consuming during exercise at fast heart rates, when it's harder to digest food.
Easy to consume
Another plus is that you can consume the SiS Go Isotonic Energy Gels without any water or sports drinks. This makes the gels ideal during high-intensity efforts when it's hard to drink large quantities of water. The isotonic concentration also makes this gel suitable for cyclists with a sensitive digestive tract.
Proven performance
It's for good reason that the SiS Go Isotonic Energy Gels received the Queens Award, a prize for exceptional innovative performance. The Go Isotonic Energy Gels are often prominently present at pro sporting events, and are consumed every day by thousands of endurance athletes across the world.

Recommended use: Ideal for consumption during exercise. Tear off the top of the sachet and drink! These gels can be taken without water.
Recommended dosage: The most common cause of fatigue is the depletion of carbohydrate reserves during exercise. Replenishing carbohydrates before and during exercise can improve (cycling) performance. If the workout lasts longer than 90 minutes, it's recommended to consume additional carbohydrates. It's recommended to consume 1 to 3 energy gels per hour. Or to combine the energy gels with other sports nutrition up to an intake of 60 grams of carbohydrates per hour. A common strategy is to consume energy gels during the high-intensity phases of exercise. The digestion process of energy gels requires less blood circulation than that of other sports nutrition products.
Warning: A nutritional supplement is not a substitute for a varied diet. In addition to physical exercise, a varied and balanced diet and a healthy lifestyle are important. Do not exceed the recommended dosage. If you are following a special diet or use medication, it's safe and prudent to consult with your doctor.
