Product Overview - Sucrose and Fructose

NutriClimb Sucrose and Fructose

Welcome fellow climbers to our product overview blog series. This series is designed to help you understand each ingredient found in our Climber Pre-Workout +, why it was chosen, and how it benefits you as a climber. This will help you understand the importance of using a product designed for you and how much research goes into creating our Climber Pre-Workout +. Lets begin! 

Sucrose and Fructose 

Sucrose is most commonly found in cane sugar, fruits, or sugar beets. It is made up of two compounds, glucose and fructose.

Fructose is found most commonly in fruits and is a single compound. A mixture between the two allows the body to replenish it's glycogen storage and provides the optimal performance output.



  • Sucrose and fructose supplies the body with easy digesting carbohydrates, which is the primary source of fuel for the muscles and brain.
  • Increased endurance.
  • Combining different sources of sugar can help improve the rate of absorption.
  • In regulated amounts, these two ingredients can be one of the best endurance and energy boosters
  • Glucose (Sucrose molecule) is the sugar primarily used by the muscles and brain. All sugar molecules are eventually converted to Glucose in the body.
  • Fructose has to be broken down by the liver before it becomes glucose and is absorbed by the muscles and brain, this allows a more slow release effect and helps with sustained energy.  

Why sucrose and fructose and how does it help climbers?

Using sucrose and fructose allows our product to be made without artificial sweeteners or flavors, which has been shown to be worse for athletes. The right types of sugars consumed at the right time at the right amount has been shown to increase endurance, energy levels, and recovery in athletes. Our mixture between sucrose and fructose allows you to get the quick release energy benefits of the glucose molecule found in sucrose as well as the slow release lasting energy benefits of fructose. 

According to Eric Horsts "Training for Climbing" he talks about accelerating the recovery process. He explains that consuming the right carbohydrates at the right time can speed up recovery time. The gylcemic index shows how fast or slow a carbohydrate is absorbed in the blood stream. "In a stop-and-go sport like climbing, steady blood sugar is vital for maintaining steady concentration and steady energy. Therefore, consume only low and medium-GI foods while you are still engaged in physical activity." Fructose has a glycemic index of 23 (Table 9.2), which means it is excellent at maintaining steady concentration and energy. He also adds "Ingesting high GI foods immediately after exercise substantially increases the rate of muscle glycogen replacement." Glucose (molecule that makes up sucrose) has a glycemic index of 100 (Table 9.2). Concluding that glucose is the best option for quickly replenishing muscle glycogen levels after climbing or training.

We believe that the best products for a climber are the ones developed with a climber in mind. We don't create generic products and try to market to climbers like most companies. We only create products with ingredients specifically researched and tested to benefit you as a climber, nothing more or nothing less.
