From Olive Leaf to Oleuropein Powder

The process is simple but carefully controlled.
• First, we source quality Olea europaea L. leaves.
• Next, the leaves undergo water-alcohol extraction to release the actives.
• Then, the extract is purified, concentrated, and spray-dried into a fine powder.
• Finally, it is standardized to a stable oleuropein powder for batch-to-batch consistency.
Moreover, the resulting powder flows well, dissolves easily, and blends smoothly into capsules, tablets, and drink mixes.

Benefits

Oleuropein is one of the most studied polyphenols from olive leaves. Its key benefits include:
• Cardiovascular health — supports normal blood pressure and healthy circulation.
• Antioxidant protection — helps protect cells from oxidative stress.
• Immune support — contributes to a healthy immune system.
• Healthy aging — a natural polyphenol for long-term wellness.
Furthermore, olive polyphenols carry a recognized EU health claim on protecting blood lipids from oxidative stress. This gives your formula a credible, science-backed story to tell consumers.

Applications of Olea Europaea L. Leaf Extract Powder

This versatile ingredient fits a wide range of finished products:
• Dietary supplements (capsules, tablets, and powders)
• Heart health and immune formulas
• Functional foods and beverages
• Skincare and personal care products
Beyond supplements, it is also used in functional drinks, where its water-soluble powder is easy to formulate.

FAQ

What botanical extracts do you offer?

Our portfolio spans standardized botanical extracts and naturally derived active compounds at every scale. That includes branded ingredients with proven bioavailability, and tailored OEM/ODM solutions — think custom premixes, stick-pack blends, and ready-to-mix solid beverages.

We’re a manufacturer. Our extraction and formulation facility occupies 4 hectares (60 Mu) in Shaanxi’s Yangling Agricultural Demonstration Zone, operating under ISO 9001 quality management with Kosher and Halal certification. Every batch is produced, tested, and released on-site — we don’t outsource production or skip release testing.We prioritize locally sourced raw materials and partner exclusively with GACP-compliant growers. This gives us full traceability from field to finished product and supports biodiversity conservation. Every batch is identity-verified, purity-tested, and checked for batch-to-batch consistency before release.

Yes. We know that in-house validation is a critical step in your R&D process. We typically supply 30 g of product at no charge for evaluation purposes. While the sample itself is free, we ask that you cover the international shipping cost — which is fully creditable against your first bulk purchase order.
