Infinit Nutrition Australia introduces Premium Fuel: The perfect custom blended liquid nutrition designed for athletes wanting to 'UP' their carb game. 


What makes Premium Fuel stand out is its unique 2:1 blend of Maltodextrin to Fructose, allowing the body to absorb more carbohydrates during those extended training sessions. While typical sports nutrition products allow for an absorbtion rate of 60 grams per hour, Infinit's Premium Fuel increases your carb intake to 90 grams per hour - promoting improved athletic performance and facilitating optimal fluid delivery. 


What is Fructose? 

Fructose, often associated with high fructose corn syrup in processed foods, is the natural sugar food in fruit. Over the years it's gaining recognition in endurance nutrition for its potential to enhance athletic performance, power output and recovery.


So, lets break it down. What exactly is fructose?

Fructose is a naturally occuring simple carbohydrate. Like glucose, fructose is a monosaccharide - one of the most basic and simplest form of carbohydrates there is. However it is important to note that although glucose and fructose are both simple sugars they differ in a few ways. 


Glucose Vs. Fructose

1. Fructose is naturally found in fruits, vegetables, and honey. Where as glucose is found more commonly in starchy carbs like rice, bread, oats and pasta. 

In Sports Nutrition, fructose is usually found in the crystalline (granulated) form. Whereas, glucose is often found in the form of dextrose (powdered glucose) or maltodextrin (the long chain form of glucose structures). 


2. Sweetness

Fructose as you have probably heard us say if you have had a call with us is FAR sweeter than glucose. 

Pure fructose can be up to 2x sweeter than high fructose corn syrup and about 1.5x sweeter than cane sugar. This is often why you see fructose used in products marketed as low sugar as it creates a way higher level of sweetness. 


3. Impact on blood sugar

Consuming glucose has a larger effect on blood glucose than fructose does. 

Your glyceamic index (GI) is a measure of how carbohydrates affect blood glucose levels. To give you an idea of how this works, glucose has a high GI (100) because it is rapidly absorbed into the bloodstream, causing levels to increase quickly. High fructose corn syrup has a medium GI (65), similar to table sugar. Whereas Fructose has a low GI (19), meaning it does not cause rapid spikes or drops in blood sugar levels. 


4. Absroption and Metabolism 

The biggest key difference between glucose and fructose is how they are processed in the body. This difference in metabolism contributes to fructose's effectiveness as a fuel source, especially for athletes.


The absorption process in the gut further highlights the advantages of fructose. Glucose and fructose are absorbed using seperate transporters, fructose having its own (GLUT5). This unique pathway allows fructose to be absorbed and converted into energy even when the system is completely saturated with glucose-based carbs, providing a significant boost in fuel intake. 



What does this mean for you and your Performance?

 Research shows that consuming both carbohydrate sources (Glucose and Fructose) can help athletes take in more fuel, and in turn produce more energy to enhance their performance. Hence why with INFINIT we can get you up to 90g PER HOUR. 


Since glucose is absorbed using one type of transporter in the gut (SGLT1), the system can become overused and thus oversaturated limiting the amount of energy that can be generated. Fructose, with its independant transporter, becomes a game changer in maximising fuel absorbtion and utilisation for optimal athletic performance.
