Description
A high-purity Hydroxytyrosol extract isolated from Olive leaf and olive mill wastewater (Olea europaea). Hydroxytyrosol is the principal phenolic antioxidant of olive oil and is among the most-studied dietary antioxidants in the cardiovascular and Mediterranean-diet research literature.
Light yellow to brown free-flowing powder or viscous liquid. Highly water-soluble.
We supply food-grade Olive Leaf Hydroxytyrosol Pure from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Companion market grades include 20 percent Hydroxytyrosol (the cost-effective baseline), 40 percent Hydroxytyrosol (standard supplement grade), 60 percent Hydroxytyrosol (premium grade), and Pure Hydroxytyrosol 98 percent or higher (the high-end pharmaceutical-feedstock grade documented here).
Bulk and reduced-MOQ shipments. Batch-level COA covering hydroxytyrosol content (HPLC), tyrosol content, oleuropein content, residual solvents, heavy metals, and microbiology.
Introduction
Hydroxytyrosol was identified as the principal phenolic antioxidant of olive oil in the 1990s and has subsequently emerged as the most-studied compound in the Mediterranean-diet research literature. Industrial production proceeds by extraction from olive leaves (the highest natural source) or by purification from olive mill wastewater (the polyphenol-rich co-product of olive oil production).
Recognized as a permitted food ingredient by the U.S. FDA (GRAS), the European Food Safety Authority, and equivalent regulators worldwide.
The EU authorizes a specific health claim for olive oil polyphenols regarding protection of blood lipids from oxidative stress, requiring a minimum 5 mg per day intake of hydroxytyrosol and its derivatives. This regulated health claim has supported substantial growth of hydroxytyrosol-standardized supplements meeting the specification.
Clinical evidence supports applications in cardiovascular endpoints (LDL oxidation, endothelial function), inflammation markers, and metabolic syndrome at supplement doses. The compound shows exceptional bioavailability among dietary polyphenols.
Strategic positioning targets premium cardiovascular and antioxidant supplements specifically, with the EU health claim supporting differentiated regulatory positioning over competing olive leaf extracts standardized only to oleuropein.
