KEY FINDINGS:
Cardiovascular Health
- Olive leaf extract (OLE) supplementation significantly reduced daytime and 24-hour systolic and diastolic blood pressure in pre-hypertensive males.
- The study involved 60 pre-hypertensive males who consumed OLE (136 mg oleuropein; 6 mg hydroxytyrosol) daily for 6 weeks in a randomized, double-blind, controlled, crossover trial.

Postmenopausal Symptoms
- Twelve weeks of daily OLE supplementation improved postmenopausal symptoms and bone mineral density in the right arm of postmenopausal women.
- The randomized, double-blind, placebo-controlled parallel study included 60 healthy postmenopausal women aged 47-70 years who received either 250 mg/day of OLE or placebo for 12 weeks.

RESEARCH QUALITY ASSESSMENT:
- The studies were well-designed, employing randomized, double-blind, placebo-controlled methodologies, enhancing the reliability of the findings.
- Sample sizes varied, with some studies involving a relatively small number of participants, which may limit the generalizability of the results.
- The duration of interventions ranged from single acute doses to 12 weeks, providing insights into both short-term and longer-term effects of OLE.
- Further research with larger sample sizes and diverse populations is needed to confirm these findings and elucidate the mechanisms underlying the observed effects.
