The available amount of carbohydrates in the body is a factor hat determines performance during long periods of physical exercise that lasts several hours. As such it is important that carbohydrates are replenished before and during this exercise. Carbohydrates will help to maintain the blood glucose level during exercise and replenish muscle glycogen(sugar stored in muscle). If no carbohydrates are consumed (from drinks, bars or gels) during this type of exercise, muscle glycogen will be depleted in about 90min. An athlete’s option includes the consumption of drinks, energy bars or gels.

How many carbohydrates should I take during exercise? 

    • Exercises < 1h: not necessary to consume carbohydrates during exercise .
    • Exercises 1-2h: 30g carbohydrates per hour
    • Exercises 2-3h: 60g carbohydrates per hour exercise.
    • Exercises >2.5-3h: up to 90g carbohydrates per hour exercise.

The benefit of an Energy Gel compared to a carbohydrate-rich drink is that a gel is a highly concentrated source of carbohydrates. In order to consume as many carbohydrates from an Isotonic drink or similar, you must consume half a litre of the drink, which can cause stomach ache. Compared to an Energy Bar, a gel will be absorbed much faster (absorbed after 10 minutes!) because it contains no protein or fat that slows emptying of the stomach.

The Isotonic Drink Energy Gel is  an isotonic gel, what means that the number of particles of the gel is equal to the number of particles in the blood. This leads to moisture, carbohydrates and minerals being optimally absorbed. The advantage of this gel is that it can be consumed without water. This makes it ideal for taking it with you, for example, if you are a runner dependent on taking your supply of energy with you. 

Who will benefit from the Isotonic Drink energy Gel?

These gels are suitable for all athletes who need to quickly replenish their energy during prolonged exercise:

  • DURING Endurance sports: cyclists, triathletes, duathletes, long-distance runners, long-distance  swimmers, etc.
  • BEFORE the start or DURING REST PERIODS for team sports.


1-3 gels per hour exercise, dependent of exercise intensity and duration.

Can be used without water.
