The Active Ingredient Is: Olive Leaf Extract (Oleuropein-rich)

Olive leaf extract is a plant-derived supplement component recognised for its antioxidant and immune-modulating properties.

This liquid extract is standardised to 18 per cent oleuropein and is supplied as an alcohol-free glycerite from olive leaves, with glycerin and water as the solvent matrix.

What Does Olive Leaf Extract Do?

Olive leaf extract participates in normal antioxidant defences and supports immune function in line with EFSA guidance on polyphenol activity.

Oleuropein, the main polyphenol, helps maintain oxidative balance and supports the body’s natural immune resilience through its antioxidant actions.
