Gel is the most effective energy.
We finished it.

Gel is the most efficient energy the body can get during endurance performance. That's why we designed it to work on the body's terms: carbohydrates in a 1:0.8 ratio and low-osmolarity DE10 maltodextrin are absorbed efficiently and leave the stomach undisturbed — energy flows freely when you need it most. And you dose it according to what your body demands right now — not according to a predetermined serving size.

The recipe is not based on trends but on research-backed knowledge of absorption.

SISU ENERGY GEL combines maltodextrin DE10 and crystalline fructose, which use two different transport proteins—SGLT1 and GLUT5—simultaneously for maximum absorption.
