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.
