OLEUS Pre-Activity 2.0 primes your mitochondria for improved endurance during training and races. Take it one hour before your next session to sustain performance and delay fatigue.

Oleuropein: to prime mitochondrial function.

L-Carnitine: to delay fatigue.

L-Citrulline: to lower lactate levels and support blood flow.

Magnesium: for electrolyte balance.

Vitamins B6 and C¹⁶⁴: to support energy metabolism.

Caffeine from Guarana: to boost energy and endurance.

Delayed fatigue: Our patented ingredient Oleuropein provides mitochondrial priming, helping you push further¹.

Endurance performance: Caffeine from Guarana keeps you going stronger for longer.

Improved blood flow: Enhances oxygen uptake, delivering more energy to your muscles for better performance¹⁰.

ATP support: L-Citrulline helps maintain ATP levels, supporting faster muscle recovery and reduced fatigue.

Neutral flavour with a hint of blueberry and a mild bitter taste from the active ingredient, olive leaf extract. Best served chilled.

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

Trusted by 10,000+ endurance athletes to power every adventure.

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

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 Recovery 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.

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.

Yes OLEUS products are doping free. We are committed to clean sports. All of our product are tested regularly for selected doping substances.

More information on the testings can be found here.

Not a gel. Endurance powered by your mitochondria.

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

Science born in Switzerland

OLEUS was born in 2017, when two Lausanne-based researchers set out to understand how different molecules support mitochondrial function. Their search led to Oleuropein, a natural compound found in olive leaves. Their work became the foundation for OLEUS, created to boost endurance at its source: your mitochondria.
