RD Health Ingredients is specilized in Olive leaf extract production and refining the producting technology, to get more pure olive leaf extract, and to make it contains more active ingredients. Recently, a study published in the British Journal of Nutrition states that consuming olive leaf extract products may have a positive effect on measures associated with cardiovascular disease (CVD) [June 8, 2015].
Olive leaf extract is mainly getting from the dried leaf of Oleo euripeal L. As the leaves of the olive plant are rich in polyphenols, of which oleuropein and hydroxytyrosol (HT) are most characteristic. Such polyphenols have been shown to have a positive impact on cardiovascular risk factors, and have been widely used as dietary supplement, and also for the cosmetics use.
Here is the research data about this study, to emphasis the function of olive leaf extract on human study.
The researchers conducted a randomized, double blind, placebo-controlled, crossover, acute intervention trial with 18 healthy volunteers, who consumed either Olive leaf extract (51 mg oleuropein; 10 mg HT), or a matched control (separated by a four-week wash out) on a single occasion.
The researchers found a single recommended dose of Olive leaf extract improved blood vessel function and lowered the inflammatory market in the blood compared to participants in the placebo group. These results provide the first evidence that Olive leaf extract positively modulates vascular function and IL-8 production in vivo, adding to growing evidence that olive phenolics could be beneficial for health.
Olive leaf extract may be a beneficial inclusion in heart-healthy bars and other foods aimed at cardiovascular health. But on the larger scale, olives in their many forms, provide wellness benefits–from olive oil for salad dressings to olive oil in Mediterranean foods and dips such as hummus.
