Product Overview

Olive Leaf Extract is a phytochemical-rich botanical ingredient derived from the leaves of the olive tree (Olea europaea), standardized primarily for its key bioactive compound, oleuropein, along with hydroxytyrosol and other polyphenolic constituents . 

Produced through advanced aqueous or ethanol-based extraction and purification technologies, it delivers a concentrated source of potent antioxidants and anti-inflammatory agents . 

In nutraceutical and functional food applications, it is widely utilized to support cardiovascular health by helping to maintain healthy blood pressure and lipid profiles, to promote healthy blood sugar metabolism, and to strengthen immune function through its broad-spectrum antimicrobial and antiviral properties . Its powerful free-radical scavenging activity also makes it a valuable ingredient in anti-aging and skin health formulations, protecting against oxidative stress and supporting overall cellular wellness.
