Endurance for the adventurous.

We believe the world's most incredible adventures require more than just fuel and hydration. That's why we created a system that unlocks endurance by optimising how your body converts energy.

Three formulas to build, boost and recover endurance.

OLEUS supports every stage of your endurance journey, by unlocking endurance at it's source, the mitochondria.

Endurance unlocked at it's source, the mitochondria

OLEUS targets the organelles that convert fuel, water, and oxygen into energy. The result? Higher energy efficiency for lasting endurance.

Science born in Switzerland

OLEUS began in 2017 when two researchers studied natural polyphenols that activate mitochdonria function. Their work laid the foundation for meaningful discoveries on endurance, with multiple patents and publications in highly regarded, peer reviewed journals.

Tested by a Pro-Cycling team

OLEUS partnered with a World Tour Pro Cycling team in a placebo-controlled trial. 28 riders took part in a multi-day endurance test, confirming OLEUS’s ability to unlock endurance.
