Pre-Activity Shot
Prime your mitochondria to boost endurance in training and races, while also optimising blood flow, alertness, and oxidative balance. Our enhanced 2.0 formula was clinically tested with a World Tour Pro Cycling team.
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.
Clinically tested with a World Tour Pro Cycling team
Performance gains of 25% more power and 38% lower fatigue were verified in a placebo-controlled trial with 28 elite riders from a Switzerland-based World Tour Pro Cycling team.

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.
