Hydroxytyrosol is currently believed to be one of the strongest free-radical scavenging polyphenols in use. Hydroxytyrosol is produced by olive, normally the olives used in the production of olive oil. The majority of extracted hydroxytyrosol can be found in the byproduct water produced during the pressing process. The most of the polyphenol can be recovered to process extracts for preventative and medicinal use. Hydroxytyrosol is the main polyphenol, along with other less potent polyphenols, found in olives.
