Shipping from 1st October, 2025
The Marathon Collection is designed to support your final two weeks of preparation and race day, from final long runs and tapering runs to race day performance. Each shot works to optimise your mitochondria, helping to reduce fatigue, provide lasting energy, and support faster recovery.
The pack combines potent ingredients like Oleuropein¹⁴, a powerful antioxidant known for enhancing cellular energy production, Magnesium³ and Vitamins B6 & C¹⁶ to reduce fatigue and optimize performance. BCAAs⁸ aid in muscle recovery, while Guarana¹³ delivers an extra energy boost, and Acerola⁹ provides antioxidants to combat oxidative stress.
Pre-Activity Shot: Enhances endurance, delays fatigue, and fuels performance with Caffeine and Guarana¹³.
Recovery Shot: Promotes muscle repair with BCAAs and Whey Protein⁶, while antioxidants like Acerola help speed recovery⁹.
Daily Shot: Supports steady energy and cognitive function through Magnesium, Vitamins B6 & C, and Siberian Ginseng⁵.

Your Marathon Toolkit
OLEUS shots target the mitochondria, sustaining your energy at the cellular level so you can focus on the adventure, not the limitations.
Empowering 5,000+ endurance athletes on their adventures
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 began in 2017, when two Lausanne researchers studied Oleuropein, a natural compound in olive leaves, alongside other molecules to support mitochondrial function. Their work laid the foundation for OLEUS, created to enhance endurance at its source: your mitochdonria.
