Olive Leaf
Extract
Olive leaf extract, rich in oleuropein, is used for cardiovascular support, immune health, and antioxidant benefits.
Derived from the leaves of the olive tree (Olea europaea), olive leaf extract contains compounds like oleuropein and hydroxytyrosol, which are credited with its health-promoting properties. It is commonly used as a dietary supplement in the Mediterranean region and beyond, primarily for cardiovascular, immune, and antioxidant support.
There is moderate evidence from randomized controlled trials and preclinical studies for cardiovascular and antioxidant benefits, and emerging evidence for antimicrobial effects.
Cardiovascular Support
ModerateOlive leaf extract may help lower blood pressure and improve certain cardiovascular risk factors, particularly in people with borderline or mild hypertension.
Antimicrobial and Immune Support
LimitedOleuropein and related compounds show antimicrobial and antiviral activity in vitro, suggesting a potential role in supporting immune defenses.
Antioxidant and Anti-inflammatory Effects
ModerateOlive leaf extract acts as an antioxidant and may modestly reduce markers of inflammation and oxidative stress in humans and animal models.
