Each serving contains 100 mg of caffeine and provides 25 grams of carbohydrates.
Made with seven ingredients—without added colors, preservatives, or flavors.
The GEL 100 CAF 100 contains 100 mg of caffeine—equivalent to 1.5 espressos—or a cup of brewed coffee. That is a lot compared with many traditional gels. It delivers 25 grams of carbohydrates in a unique blend of fructose and glucose (0.8:1 ratio). It offers a high weight-to-energy ratio and contains no added flavors, preservatives, or colors. Like all our products, it is vegan.
Use the GEL 100 CAF 100 on its own for short durations or combine it with other Maurten products to ensure you have enough carbohydrates throughout your session.
WHY CAFFEINE? Caffeine has been shown to promote alertness and reduce perceived effort and pain. These properties can be beneficial for sports performance. The GEL 100 CAF 100 can be used to increase caffeine levels—on its own, in combination with other sources of caffeine, such as regular coffee—or to reach sufficient caffeine levels during physical activity.
AMOUNT OF CARBOHYDRATES It is well known that our bodies can use approximately 60 grams of ingested carbohydrates per hour in the form of glucose or maltodextrin (a glucose polymer). Using a combination of fructose and glucose/maltodextrin at a 0.5:1 ratio allows absorption of up to 90 grams per hour. More recent studies have shown that increasing the fructose content above 0.5:1 allows even greater absorption. The GEL 100 CAF 100 is based on a fructose/glucose ratio of 0.8:1. One serving contains 25 grams of carbohydrates.
Usage guidelines
Developing a nutrition strategy for races or key sessions is complex. Everyone is different, and the rate of caffeine absorption and metabolism varies from person to person.
Caffeine concentration generally peaks within 60 minutes, but normally takes 3 to 5 hours to reach half its level. It is important to consider two other important factors: 1) your body weight and 2) your caffeine intake. Science suggests an intake of 3 mg of caffeine per kilogram of body weight to improve performance. But again, this is highly individual.
Maurten has developed general guidelines for using the GEL 100 CAF 100, based on its own results and the scientific literature:
DURATION <1 HOUR
This strategy would require 1 serving of GEL 100 CAF 100.
BEFORE: A beneficial level of caffeine can be reached by consuming approximately 200 mg before the activity. To do this, consume, for example, a cup of coffee in the hours before the event and a GEL 100 CAF 100 during your warm-up.
DURING: No consumption is necessary.
DURATION <2 HOURS
This strategy would require 2 to 3 servings (depending on body weight) of GEL 100 CAF 100.
BEFORE: Aim to consume 200 mg of caffeine before the activity. This simply means consuming two GEL 100 CAF 100. For an event lasting approximately two hours, having a GEL 100 CAF 100 during your warm-up is a practical way to increase caffeine levels—and carbohydrate levels at the same time. Remember that one GEL 100 CAF 100 contains 25 grams of carbohydrates.
DURING: After approximately thirty minutes of activity, consume another GEL 100 CAF 100 to ensure that you maintain a sustained caffeine level. Do not forget to replenish carbohydrates. Try to consume 30 to 60 grams of carbohydrates per hour.
DURATION 2–6 HOURS
This strategy would require 2 to 4 servings (depending on duration and body weight) of GEL 100 CAF 100.
BEFORE: Consume 200 mg of caffeine during the hours preceding the event.
DURING: After approximately thirty minutes of activity, consume another GEL 100 CAF 100 to ensure that you maintain a sustained caffeine level. Try to consume one GEL 100 CAF 100 every two hours to maintain caffeine levels. Do not forget to replenish carbohydrates—either by using GEL 100, drinking Drink Mix 160, or Drink Mix 320. This is ambitious, but aim to consume approximately 60 to 90 grams of carbohydrates per hour.
IMPORTANT These guidelines are simplified and should only be used as a general guide. Caffeine is not for everyone. If you have any doubts or are pregnant, consult a doctor. And always keep in mind that there is no benefit to increasing your caffeine intake. You can never compensate for training, and consuming too much will not help you.

Mon meilleur partenaire pour une course ce gel Maurten !
De lemballage jusquau goût (assez neutre) cest tout simplement parfait.
A sortir pour les grandes occasions car assez onéreux mais résultats garantis !
Je ne suis pas prêt de changer.

Bonjour, lors de mon marathon sur lIronman à Emilia-Romagna, jai pris 1 gel sur 3/heure de 100CAF, et terminé celui-ci en 3h40 à 56ans. Super content des produits. Aucun reflux gastrique, goût relativement neutre
