Hydroxytyrosol is believed to be the antioxidant with the highest free radical scavenging capacity: double that of quercetin and more than 3 times that of epicatechin. The wastewaters generated during olive processing contain a high levels hydroxytyrosol, most of which can be recovered to produce hidroxytyrosol extracts. Studies by Visioli et al (2000) showed that a low dose of hydroxytyrosol reduces the consequences of sidestream smoke-induced oxidative stress in rats.

Health Benefits of Hydroxytyrosol
Hydroxytyrosol has the same health promoting properties than other polyphenols: prevention of atherosclerosis, promotion of intestinal and respiratory health and prevention of cancer. Hydroxytyrosol also reduces the oxidative stress caused by smoking.
