Oleuropein, an excellent cardiovascular protector

by 12,922 Comments

We, at Deretil Nature, also offer our customers NaturOlive OE, a standarized olive leaf extract with high purity in Oleuropein. Oleuropein is another treasure of the Mediterranean diet that is recognized because of its valuable beneficial properties in preventing cardiovascular diseases.

Oleuropein is the major antioxidant component of green olive pulp and olive leaves, which grants EVOO its particular bitter taste and important healthful properties.

The beneficial effects of olive polyphenols, such as Oleuropein, have been recognized by the EU Risk Assessment Body for Food and Feed Safety (EFSA Journal 2011; 9 (4):2033). This scientific statement, with more than 2.500 articles and entries among research studies and patents, support the healthful properties that Oleuropein provides to our health. Apart from highlighting its high antioxidant and antimicrobial activity, it has also important therapeutic properties as cardioprotective, anti-inflammatory, lowering blood pressure and anti-cancer remedy.

Main biological benefits for cardiovascular health:

Prevention of cardiovascular diseases: It contributes with antioxidant benefits to prevent the oxidation of cholesterol LDL (“bad” cholesterol), being able to favor a good coronary function. LDL oxidation causes development of atherosclerotic injuries and formation of atheromatous plaques.

Reduction of blood pressure and vascular system protection: Different studies prove that Oleuropein, administered intravenously, reduces blood pressure and dilates coronary arteries. In fact, Oleuropein can inhibit the oxidation of cholesterol carried by low density lipoprotein (LDL), which results into a potential effect of Oleuropein to prevent heart diseases.

Anti-inflammatory activity: Oleuropein is responsible for the beneficial effects against inflammation and platelet aggregation. Scientific studies show that Oleuropein increases nitric oxide production in macrophages stimulated by lipo-polysaccharides. In addition, Oleuropein has got an anti-inflammatory effect because of the inhibition of lipoxygenase activity and leukotriene B4 production.

A daily dose of 50 – 100 mg contributes to all the aforementioned functionalities, while improving and maintaining our cardiovascular system.
