Olive Leaf Extract Powder

Premium Olive Leaf Extract Powder - Standardized Oleuropein & Hydroxytyrosol for Nutraceutical & Functional Food Applications

Xi'an Jiayuan Bio-tech Co., Ltd. delivers pharmaceutical-grade Olive Leaf Extract Powder standardized to Oleuropein (10-80% HPLC) and Hydroxytyrosol (3-20% HPLC), sourced from Mediterranean Olea europaea L. leaves. Since 2002, our GMP-certified factory has been providing botanical solutions high in antioxidants to worldwide makers of nutritional supplements and functional foods. Our extract has a total phenolic content of up to 1289.95 mg GAE/L and antioxidant capacity of up to 19.02 mmol Fe 2 + /L, which translates into better cardiovascular, neuroprotective and metabolic health advantages. ISO22000 HALAL KOSHER FDA compliant. We support MOQ from 1kg with customised specification.

What Is Olive Leaf Extract Powder?

For the extraction from Olea europaea L. leaves, optimised water or ethanol extraction and spray drying are employed to get the concentrated bioactive component. Crushed leaf powder is devoid of oleuropein (60-90 mg/g dry weight) and its metabolite hydroxytyrosol.

It eliminates indigestible plant fibre in the extraction process and normalises active markers to uniform specifications. This addresses key formulation difficulties like bioavailability improvement and dose predictability that raw ingredients cannot overcome.

For B2B procurement teams, our powder solves three main pain points: First, it provides quantitative bioactivity based on HPLC-verified oleuropein concentration rather than nebulous ratios. Secondly, the fine particle structure (≥80 mesh) provides excellent dissolving in capsules, tablets and beverage systems. Third, the shelf life is prolonged to 24 months in stable powder form under optimal storage conditions, which reduces inventory waste.

Functional beverages, encapsulated supplements, and food fortification using clean-label plant-based antioxidants may use this brown-yellow to greenish powder with good water solubility.

Core Functions & Health Benefits

Support Cardiovascular System

There is clinical evidence that phenolic compounds may influence healthy blood pressure levels and adequate coronary blood flow. The extract reduces LDL cholesterol oxidation and helps in regulating the cardiovascular rhythm.

Enhanced Antioxidant Defence

Optimised extracts with total phenolic content over 1289 mg GAE/L were shown to have high free radical scavenging activity of the powder. This helps preserve cellular frameworks from damage by oxidative stress and promotes healthy ageing processes.

Neuroprotective Properties

Oleuropein and Hydroxytyrosol Cross the Blood Brain Barrier to Provide Targeted Neuroprotection Research has shown these compounds reduce brain inflammation, boost the mitochondria and may help to remove amyloid-beta plaques associated with cognitive decline.

Metabolic Health Management

These bioactive compounds enhance glucose metabolism and insulin sensitivity and are therefore a superb metabolic health solution for blood sugar management.

Natural Antimicrobial Activity

The extract has a wide antibacterial capability against bacteria and fungus, making it applicable in immune-support supplements and natural food preservation systems.

Application Fields

Industry Sector	Specific Applications
Dietary Supplements	Cardiovascular capsules, antioxidant tablets, cognitive health softgels, immune support sachets
Functional Beverages	Ready-to-drink wellness shots, sports hydration drinks, functional teas, anti-aging beauty beverages
Food Fortification	Functional bars, healthy snacks, dairy alternatives, salad dressings with natural preservation
Cosmeceuticals	Anti-aging serums, skin protection creams, hair care formulations (ingredient stability requires evaluation)
Animal Nutrition	Pet supplements, livestock feed additives for oxidative stress management

The powder's microencapsulation compatibility with maltodextrin or gum arabic carriers enhances handling properties for tablet compression and beverage clouding applications.
