The Evidence for Olive Leaf’s Cardiovascular Benefits Just Got Bigger.
Though less famous than olives and olive oil, olive leaves contain way more of the beneficial phenolic compounds and may be even better for your heart.
Studies have shown that olive leaf extract improves cholesterol (Eur J Nutr 2017;56(4):1421-1432) and, especially, blood pressure (Phytother Res. May 2025;39(6):2863-74). One study has even suggested that olive leaf extract is as effectively as the drug captopril for lowering high blood pressure.
A new systematic review and meta-analysis has now added to the evidence for olive leaf extract as an important heart herb.
30 controlled studies were included in the analysis. The meta-analysis demonstrated that olive leaf extract significantly reduced total cholesterol, the damaging LDL cholesterol, oxidized LDL cholesterol and triglycerides. Apolipoprotein A1, the major protein in the heart healthy HDL cholesterol rose significantly. Higher levels of apolipoprotein A1 mean lower risk of heart disease.
Olive leaf extract also continued its impressive record for blood pressure, significantly reducing both systolic and diastolic blood pressure.
And here’s a bonus for you and your heart. Olive leaf extract also significantly reduced body mass index and weight.
This carefully designed study adds to the growing body of evidence suggesting that olive extract is an important herb for heart health.
