Oleuropein is a plant-based phenolic compound with antioxidant activity and is the main active polyphenol in olive leaf extract. This form is derived from olive leaf and is standardised for oleuropein content, providing a plant-based ingredient option for normal body functions.

The extract is plant-based and supplied in a form consistent with olive leaf material, offering a natural source of oleuropein within a well-characterised extract.

The Active Ingredient Is: Oleuropein (in Olive Leaf Extract)

Oleuropein plays a role in antioxidant protection and may support immune function, with additional effects described on cardiovascular function such as supporting blood vessel performance and cholesterol management in research contexts.
