What Makes Our Hydroxytyrosol Extract Superior?
Hydroxytyrosol is the metabolically active shape of oleuropein. It's far a concentrated component that allows you make vital components choices. Not like raw olive leaf powders, which don't usually work, our 20% standardized extract works the equal manner each time.
This small-molecule polyphenol easily gets through biological barriers like the lipid layer on the skin and the blood-brain barrier. That means your finished goods will have real bioactivity, whether you're making supplements for heart health or skin care that fights aging.
We only use water and ethanol in our extraction process, so there are no dangerous solvents left over. As a result, there is a clean-label ingredient that appeals to today's health-conscious consumers and has great water solubility for a wide range of formulation choices.

Diverse Application Scenarios for Your Business
Supplements for Cardiovascular Health
Your customers want heart health solutions that work. Our extract stops the oxidation of LDL cholesterol and helps keep blood pressure in a safe range. Even after being compressed under high pressure, it keeps its bioactivity. This makes it perfect for capsules, tablets, and soft gels.
Nutricosmetics and Premium Skincare
The extract increases the production of glutathione and shields melanocytes from damage caused by UV light. At pH 3.5 to 5.5, it stays stable and can be added to anti-aging serums, beauty shots, and topical formulations. This will give your customers results they can see.
Functional Foods and Beverages
Add quick cold-water solubility to your heart-healthy energy drinks, functional waters, and nutrition bars to make them better. Up to 120°C, our Olive Leaf Extract 20% Hydroxytyrosol is thermally stable, meaning it can withstand normal pasteurization without losing any of its potency or flavour.
Health Product Formulations
Whether you're making immune support formulas or all-around wellness blends, this extract has strong free-radical scavenging activity at low inclusion rates. This will make your product work better while keeping costs down.
Rigorous Quality Control You Can Trust
We know that inconsistent quality makes it hard to meet your production goals and hurts the reputation of your business. That's why HPLC quantification is done on each batch to check the real hydroxytyrosol content, not just the total polyphenols.
Full microbial panels that include Total Plate Count, Yeast/Mold, E.coli, and Salmonella are part of our thorough testing. To make sure we follow the strict EU and USDA organic rules, we do multi-residue pesticide research.
All of our products have not been irradiated, and we test their stability in Zone IVB. This makes sure that the 20% standardization stays the same over the 24-month shelf life, even though the substance is naturally sensitive to light and water.
You can follow our whole supply chain, from our integrated planting bases all the way to your door. We allow testing by a third-party lab and offer free samples before shipping so you can check the quality before placing a big order.

FAQ
Q: What's the difference between Hydroxytyrosol and Oleuropein?
A: Hydroxytyrosol is a byproduct of metabolism that is a more bioactive form of oleuropein. It has a lot more antioxidant power and much better absorption by cells, which makes your products work better.
Q: Is this extract safe to use in food processing when it gets hot?
A: It is thermally stable up to 120°C for short periods of time. Because of this, it can go through normal pasteurization and extrusion processes without losing a lot of its potency.
Q: Why does the colour change a little from batch to batch?
A: As a natural botanical extract, the colour can vary slightly depending on when the plants were harvested and how the land was. Our HPLC standardization, on the other hand, makes sure that the 20% hydroxytyrosol potency stays the same chemically, even if it looks different.
Q: How well does this ingredient mix with water?
A: Our 20% grade is processed in a way that makes it very water-soluble, so it doesn't leave much sediment in liquid uses. This makes it easier to make drinks and other products that are water-based.
Q: What's the best way to store things so they don't bunch up?
A: Because it absorbs water, keep it in a cool, dry place below 25°C. Use sealed containers with double-lined PE bags inside fibre drums to keep powder from absorbing water and keep it flowing easily.
