Description
OLIVE POLYPHENOL
Oleuropein Powder 70%
Oleuropein is the principal secoiridoid glycoside of olive leaf, and the compound most olive leaf extracts are standardised against. It is supplied here as a purified powder at 70% content for further processing.

Buyer Decision Guide
The first decision is how the extract is described. An olive leaf extract standardised to a declared oleuropein content and a purified 70% oleuropein powder are different inputs, even though they answer to the same word on a brief.
The second decision is taste. Oleuropein is intensely bitter, and bitterness becomes the limiting factor long before the label claim does. If the dose is going into a capsule the point is academic; in a beverage it is the whole decision.
The third decision is the rest of the polyphenol picture. Oleuropein is not the only active in olive leaf, so a buyer who needs the full phenolic profile should be looking at an extract, not a purified compound.
Application Areas
- Olive leaf standardised formulations
- Antioxidant supplement blends
- Functional food and beverage
- Research and reference material

Frequently Asked Questions
How does this differ from olive leaf extract?
This is a purified compound at 70% oleuropein. An olive leaf extract carries the broader phenolic profile at a lower declared marker content.
What content is supplied?
The offered grade is 70% oleuropein, confirmed on the batch-specific certificate of analysis together with the analytical method.
Is oleuropein bitter?
Yes, markedly. Bitterness usually limits the dose in beverage applications well before the label claim does, so taste trials are worth running early.
Do you also supply hydroxytyrosol?
Yes. Hydroxytyrosol is listed separately, so the olive polyphenol range can be quoted together.
What is the minimum order quantity?
The regular MOQ is typically 1 kg, with a small evaluation sample available before a formal order subject to stock.
