    • OLE improves antioxidant activity in the brain, protecting neurons from oxidative stress.
    • Two main compounds, oleanolic acid and oleuropein, boosted fat breakdown and mitochondrial function.
    • Mice given OLE showed better endurance and exercise capacity, even without regular training.
    • Benefits likely come from OLE’s ability to enhance mitochondrial health and fight oxidative damage.
