Introduction
Olive leaves have been used as a traditional medicine across the Mediterranean for centuries for fever, infection, and what would now be described as blood pressure regulation. Modern commercial development of standardized Olive Leaf Extract emerged in the 1990s following research on the antimicrobial and cardiovascular activities of oleuropein.
Industrial production proceeds by hot-water and ethanol extraction of dried Olive leaves, followed by purification and standardization to defined oleuropein content. The leaves are typically a co-product of olive oil production.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide. The European Medicines Agency has issued draft monographs supporting traditional use for relief of mild urinary symptoms.
Oleuropein is hydrolyzed in the gastrointestinal tract to hydroxytyrosol, the small phenolic molecule that accounts for many of the documented biological activities of olive products. Clinical evidence supports modest blood-pressure reduction and LDL-cholesterol effects at appropriate doses.
Strategic positioning targets the cardiovascular-support and Mediterranean-diet supplement segments, where the natural-origin and Mediterranean-positioning narratives support premium pricing.
