Frequently asked questions


Dextrose belongs to the carbohydrates group. Along with fats and proteins, these nutrients are important to humans. Dextrose is the most important “simple sugar” and is generally called “grape sugar” or in medicinal terms “glucose”. The different names all refer to the same molecule. Dextrose is a naturally-occurring sugar found in sweet fruits and honey, for example. However, dextrose is also obtained from starch, for example maize starch, which is broken down into its individual building blocks (dextrose / glucose) by enzymes.

If there are just not enough carbohydrates and the blood sugar level drops noticeably, it is advisable to supply the body with carbohydrates immediately. If they are needed quickly, then it is best to supply them directly in the form of dextrose/glucose. It is important to ensure that a large portion is not consumed in one go, but rather small amounts in short intervals. One tablet every 15 to 20 minutes is ideal. This recommended intake helps raise the blood sugar to normal levels; Furthermore, it prevents a further drop in blood sugar levels.

Sports Nutrition

The recommendation is to try sports nutrition during training. This is because it is important to train your food and drink consumption under physical stress and to find your own drinking rhythm. This facilitates the carbohydrate and fluid intake and thus provides safety and sets up a routine for the competition.

Before the sports event, it is important to fill up your carbohydrate store, hydrate properly, and take in minerals. To do this, drink 150-300 ml of fluid about 20 minutes before starting, for example. If you want to settle your stomach or fill up your carbohydrate store, you can have a carbohydrate-rich snack such as a carbohydrate bar (an Energy Bar for instance) just before you start. This way the carbohydrate store remains full for longer.

Depending on the duration and intensity of the training or competition, fluids and minerals must be replenished to ensure performance. The recommendations for hydration are to drink up to 0.75 litres per hour, depending on perspiration and, of course, environmental conditions. No more than a maximum of 0.8 – 1 litre of liquid should be consumed, as the body can hardly absorb more liquid and this would also put too much strain on the stomach.

For optimal recovery and to support the effectiveness of training, it is important to replenish the carbohydrate store within 60 minutes after exercising in order to rebalance fluid and mineral loss, and to counteract possible muscle breakdown by ingesting protein (e.g. by taking Recovery Drink).

It is recommended that a paediatrician be consulted for questions about its suitability for children.
