PRODUCT

Endurance energy isn’t something you take, it’s something you make. Energy bars, gels, and chews are all great. But they’re just fuel. The energy your muscles need to move you, is made by your cells. They take the raw fuel from food and turn it into the ATP energy your muscles need to perform. 

OLEUS has created a complete system designed to support your cell energy metabolism² through every performance stage. Like a turbocharger improving the performance of a car engine, our patented nutrient complex enhances the cell's ability to deliver more of what our muscles need to keep firing on all cylinders³.

OLEUS was developed by a team of research scientists from the University of Lausanne specializing in mitochondrial function.

OLEUS is made for serious and amateur endurance athletes who compete or train 1-5 times per week with at least one session over 2 hours.

OLEUS headquarters are in Belgium, and we are currently producing in Italy at a facility that is GMP Certificated for Manufacturing and Packaging of Food Supplements according to the Code of Federal Regulation Title 21 - FDA.

Take one shot an hour before your next race or workout. Limit to one shot per day.

Take one OLEUS Post-Activity Shot right after your training session or competition.

Take your OLEUS Daily Shot every morning to maintain healthy cell function⁷.

This depends on the type of OLEUS shot you’re taking:

OLEUS Pre-Activity Shots should be taken 30-60 minutes before your training session or competition. For extended activities, you can take another Pre-Activity Shot mid-training if needed.

OLEUS Post-Activity Shots should only be taken after your training sessions.

OLEUS Daily Shots should be taken once a day.

OLEUS offers a complete system designed to support your cellular energy metabolism² at every stage of performance. For optimal results, we recommend using all three OLEUS shots.However, each shot provides unique benefits and can be used individually, so you can choose the one that best fits your needs.
