The Nrgy Unit System is designed to simplify energy intake calculations before and during your workout. At its heart is the Nrgy Unit, a measuring unit Nduranz created for their fueling products. 

With 45 grams of carbohydrate per Nrgy Unit, you can easily and precisely measure your energy intake without excessive calculations. 

At the same time, all products within the Nrgy Unit System are based on the same carbohydrate ratio, making it easy to combine products without worrying about digestive issues.

    Easy to Use

    Nrgy Unit was created to make your life easy

    Gone are the days when you had to calculate every gram of carbohydrate. With the Nrgy Unit System, all you need to do is add 1+1, while the science behind it is taken care of.

    One Nrgy Unit equals 45 grams of carbohydrates or 180 calories. Adjust the amount of Nrgy Units per hour to the length and intensity of your exercise.

    Optimal Fuel

    Carbohydrates are the main fuel for endurance activities, but not all sources are equal. Absorption rates differ heavily, and low absorption generally leads to digestive issues. 

    The main goal of products inside the Nrgy Unit System was to create the optimal fuel that would allow you to absorb up to 90 grams of carbohydrates per hour without digestive issues.

    Science is clear. You must to combine two carbohydrate sources (glucose and fructose) to achieve that. But just consuming two carb sources is not enough, you need to consume them in the right ratio. Research shows that is a 1:0.8 glucose-to-fructose ratio.

    Nrgy Unit System products contain carbohydrates in the optimal ratio, allowing you to absorb up to 90 grams per hour without worrying about digestive issues common at higher carbohydrate intake.
