What Makes Our Olive Leaf Extract Powder Stand Out?

Our product provides strong antioxidant support with a high level of Oleuropein. You'll appreciate the delicate balance of strength and purity we achieve in every run of manufacturing.

This substance is suitable for dietary supplements, immunological support formulations and cardiovascular health products. Its tiny particle size ensures a smooth blend into capsules, pills, powders and functional beverages. You may count on consistent solubility in both water and ethanol solutions.

We control all important quality parameters. Total heavy metals are below 10 ppm. Pesticide residues are controlled in accordance with EC 396/2005. Without irradiation, you'll still have low microbial levels, preserving the natural integrity you expect.

Health Benefits & Applications You Can Leverage

Powerful Antioxidant Protection

Oleuropein is known to scavenge free radicals and exhibit antioxidant effects. Your consumers will enjoy better cellular health and protection against environmental damage. Our product has an ORAC value that is high and thus better than many synthetic antioxidants.

Support for the Immune System

This extract can support the body's natural defenses. It's especially potent in seasonal wellness formulas where immunological resilience is most important. You can safely add it to your health-maintenance products you use everyday.

Cardiovascular Health Support

Our extract supports healthy blood pressure levels and vascular function. It's a good choice for enhancing overall heart health, which makes it an important part of cardiovascular health formulae. Oleuropein and Hydroxytyrosol work synergistically to provide full assistance.

Natural Antimicrobial and Antiviral Activity

The extract has inherent antibacterial properties. It helps your formulas defend themselves against dangerous germs. This makes it a good fit for immune boosting and general wellness products.

Versatile Application Options

You can easily incorporate this powder into multiple product formats:

Dietary Supplements: Capsules, tablets, and powder blends
Functional Beverages: Wellness drinks and liquid shots
Cardiovascular Formulas: Heart health support products
Immune Boosters: Seasonal wellness formulations
Antioxidant Products: Anti-aging and cellular health supplements

Rigorous Quality Control & Compliance Standards

Rigorous Testing Procedure

Your QA team will love how thorough our testing process is. Each batch is tested for:

Active Marker Quantification: HPLC assay shows Oleuropein concentration is exactly as stated in your Certificate of Analysis.

Contaminant Screening: We test for heavy metals with ICP-MS technology. Lead < 3.0 ppm, Arsenic < 1.0 ppm, Mercury < 0.1 ppm. Pesticide residues are screened by GC-MS/LC-MS methods.

Solvent Residue Analysis: Ethanol and Methanol are determined by USP <467> standards, ensuring the clean extraction profile your clients have come to expect.

Microbiological Control: Total Plate Count less than 1,000 cfu/g. Yeast and mold are below 100 cfu/g. We guarantee the complete absence of Salmonella and E. coli according to USP <61> and <62> procedures.

Third Party Verification

We work with globally recognized testing laboratories such as Eurofins, SGS, Alkemist Labs, and NSF. This independent verification provides you with more trust in our quality claims.

Traceability of Batch

Traceability along the entire process, from raw material source to finished product. You obtain full documentation for regulatory compliance in China, the European Union and the United States.

Physical & Chemical Properties Explained

Our Olive Leaf Extract Powder is a free flowing fine substance. The color varies from brown-yellow to pale green based on the Oleuropein content. The stronger extracts tend to be deeper brown.

The particle size of 80-100 mesh is the best for mixing in your production equipment. Bulk density is in the range of 0.40–0.60 g/ml which gives a great flowability for capsule filling and powder mixing operations.

This extract is flexible due to its solubility qualities. It is mildly soluble in water and highly soluble in aqueous ethanol solutions. This flexibility allows for both liquid and solid dosing forms.

Very good thermal stability. The powder is stable after short-term pasteurization up to 90°C. It is better than many thermally labile vitamins and synthetic antioxidants.

The complete spectrum matrix has complementary flavonoids like luteolin and apigenin. These generate synergistic benefits that frequently outperform isolated synthetic Oleuropein in therapeutic applications.

FAQ

Q: What Oleuropein concentration do you recommend for immune support formulas?

A: Many products in immune support use 20-30% Oleuropein extracts. This concentration is balanced between efficacy and cost-effectiveness. The higher concentrations (90%) are suited for premium formulations when the greatest strength per serving is desired.

Q: How do you control methanol residual below 10ppm?

A: Our approach involves the use of improved ethanol-water extraction and the careful recovery of solvents. GC testing is performed on each batch before release to ensure conformance to USP <467>.

Q: Can this extract blend well with other botanical ingredients?

A: Of course. The 80-100 mesh particle size allows for homogeneous dispersion in multi-ingredient recipes. It plays well with vitamin complexes, other anti-oxidants and herbal combinations.

Q: How long do they last?

A: In cool, dry conditions away from direct sunlight, our extract is stable for 24 months at less than 25°C. When properly packaged in sealed containers, it remains potent over that duration.

Q: Can we test samples before placing bulk orders?

A: Yes, we offer free samples for evaluation. Sample preparation is roughly 7 working days. This helps your quality team to verify specs before you buy greater volumes.

Q: What certificates are accepted for export to Europe and North America?

A: We are certified for FDA registration, ISO 9001, FSSC 22000, Kosher and Halal. These are the important international markets. We also offer third party testing reports from Eurofins and SGS on request.

Q: What is the cost for the different Oleuropein concentrations?

A: We price based on concentration because of processing needs. We offer competitive rates on all specifications and transparent quotations depending on your volume requirements.

Q: What is your method of pesticide residue testing?

A: GC-MS/LC-MS analysis in accordance with EC 396/2005 norms. The tests include more than 500 pesticide chemicals. For those customers wanting NOP or EU Organic compliance, we do have organic-certified raw materials available.
