Pure Olive Leaf Extract

 

Olive Leaf Extract is derived from the leaves of the olive tree (Olea europaea), harvested primarily during the annual pruning cycle. Its functional activity centers on oleuropein, a secoiridoid glycoside present at concentrations far higher in the leaf than in olive oil or olive fruit, along with related compounds like hydroxytyrosol and flavonoids such as luteolin and quercetin. Oleuropein content is the key specification to compare across suppliers - a product labeled simply "500mg olive leaf extract" tells a formulator very little without knowing the standardization percentage behind it.

Sheerherb's Pure Olive Leaf Extract is extracted from Olea europaea leaves and standardized to oleuropein content, with HPLC verification confirmed on every batch. We supply supplement manufacturers, functional food producers, and cosmetic formulators sourcing olive leaf raw material for cardiovascular, immune, and antioxidant-support product lines.
