Oleuropein Olive Leaf Extract

 

While standard Olive Leaf Extract is typically standardized to 20%–40% oleuropein alongside a broader spectrum of leaf compounds, Oleuropein Olive Leaf Extract refers to a further-purified version isolating oleuropein itself at significantly higher concentration - up to 90%+ purity. This distinction matters for formulators who need precise, high-dose oleuropein delivery within a small fill weight, or who are building products where oleuropein itself - rather than the broader leaf phytochemical complex - is the primary label claim.

Sheerherb's Oleuropein Olive Leaf Extract is further purified from standard olive leaf extract through additional isolation processing, with oleuropein content verified by HPLC on every batch. We supply premium supplement brands, research-application buyers, and contract manufacturers sourcing high-purity oleuropein raw material where concentrated, precisely dosed delivery is the priority.

Oleuropein Olive Leaf Extract is valued mainly for its concentrated single-compound purity, which underpins its positioning as a premium raw material:

1. High-Potency Cardiovascular & Antioxidant Formulations

Concentrated oleuropein allows formulators to hit meaningful dosing targets with a smaller fill weight than standard-grade olive leaf extract.

2. Precise, Standardized Dosing

Isolated at high purity, it offers formulators exact, batch-consistent oleuropein dosing rather than the wider compositional range typical of whole-leaf extracts.

3. Premium Single-Compound Label Claims

Its high purity supports brands building formulas around oleuropein specifically as the headline active, rather than a broader "olive leaf extract" claim.

4. Research & Specialty Formulation Applications

Higher-purity grades (90%+) are commonly used in research settings and specialty formulations requiring a well-characterized, single-compound input.

 

Premium Dietary Supplements

High-purity, concentrated oleuropein supports capsule formulations targeting a specific, standardized dose within a compact fill weight.

Research & Specialty Formulation

90%+ purity grades suit research applications and specialty product development requiring a well-characterized single compound.

Cosmeceuticals

Concentrated antioxidant activity supports inclusion in premium anti-aging serums and treatment products at low, precisely dosed inclusion rates.

 

Sheerherb produces Oleuropein Olive Leaf Extract at high purity and is certified to ISO 9001, ISO 22000, HALAL, Kosher, and GMP standards. As a supplier serving premium supplement and research-application buyers worldwide, we keep pricing competitive without compromising on purity - every batch is HPLC-verified with a full chromatogram provided.

We operate our own purification facility and R&D team, which means custom purity targeting, documentation, and sample requests are handled in-house rather than passed through a third party - giving you faster turnaround and more control over the final spec.
