What is the right glucose-fructose ratio? How can this improve your endurance performance?

During endurance sports, optimizing your energy intake is crucial to achieving peak performance. Previously, the 2:1 glucose-fructose ratio was often used, but now there is a new ratio that helps athletes perform better with less gastrointestinal distress. The 1:0.8 glucose-fructose ratio offers significant benefits, as proven by scientific research and real-world experience from countless athletes. This does not mean that the 2:1 ratio is not good; it still works well for many people and is still used in many of our products. However, the 1:0.8 ratio offers additional benefits, especially for efforts longer than three hours.

The importance of carbohydrates during endurance sports

During prolonged and intense exercise, carbohydrates are the main source of fuel. Traditionally it was recommended to consume about 80-90 grams of carbohydrates per hour, but recent research and practical experience show that intakes of up to 120 grams per hour are possible without stomach or intestinal discomfort. However, this is only achievable with the right carbohydrate ratio, which can be of great benefit especially during longer efforts.

Why 1:0.8 glucose-fructose ratio?

The right combination of carbohydrates can significantly increase the body's absorption capacity. Whereas a 2:1 glucose-fructose ratio allows up to 90 grams of carbohydrates per hour, the 1:0.8 ratio allows athletes to absorb up to 120 grams of carbohydrates per hour. This new ratio increases the efficiency of carbohydrate oxidation from 62% to 74% and reduces symptoms of gastric fullness and nausea. To fully absorb 120 grams of carbohydrates per hour, however, it is important to train for this.

Advantages of the new relationship

• Enhanced Oxidation: The 1:0.8 glucose-fructose ratio increases oxidation of ingested carbohydrates by 17% and 10%, depending on the study.
• Reduced Stomach Symptoms: This ratio reduces symptoms of gastric fullness and nausea, ideal for long and intense efforts.
• Increased Power: Research shows that this ratio increases average power during 10 maximal sprint efforts by 3% compared to the 2:1 ratio.

BYE! Nutrition products with 1:0.8 ratio

At Bye Nutrition, we now have two products with this ratio: our Endurance Booster and our new 40 Carbs Fruit Gel.

BYE! Endurance Booster

The BYE! Endurance Booster is specially designed for endurance athletes looking to achieve peak performance. This sports drink contains the innovative 1:0.8 glucose-fructose ratio, which increases carbohydrate oxidation and reduces stomach upset.

BYE! 40 Carbs Fruit Gel

The BYE! 40 Carbs Fruit Gel is a perfect energy solution for endurance athletes. With a natural smoothie flavor and 40 grams of carbohydrates per 60 ml, this gel provides fast and efficient energy. The 1:0.8 glucose-fructose ratio in this gel increases carbohydrate oxidation and reduces stomach upset, which is essential for prolonged performance. In addition, the gel contains magnesium citrate, which reduces fatigue and supports normal muscle function. Magnesium citrate is the best absorbable form of magnesium, making it ideal for athletes.

Training of stomach and intestines

To reap the benefits of high carbohydrate intakes, it is crucial to train your stomach and intestines. Start with lower amounts and gradually increase intake to get your body used to the high carbohydrate load. This process helps prevent gastrointestinal distress and ensures that you can perform optimally during races. Do the same if you want to build up to the 90 grams of carbohydrates.

Conclusion

Moving to a 1:0.8 glucose-fructose ratio offers numerous benefits for endurance athletes. With products such as the BYE! 40 Carbs Fruit Gel and the Endurance Booster, you can improve your performance while reducing gastrointestinal distress. Whether you're training for a marathon, a triathlon or a multi-day bike ride, the right carbohydrate ratio and proper gastrointestinal training are essential for success.

Experience for yourself the benefits of the 1:0.8 glucose-fructose ratio and optimize your energy intake with Bye Nutrition. Try our BYE! 40 Carbs Fruit Gel in combination with the Endurance Booster and feel the difference during your next effort!
