New clinical trial shows Olive Leaf Extract may help reduce blood pressure and cholesterol

New clinical trial shows Olive Leaf Extract may help reduce blood pressure and cholesterol

Another new and exciting study has been completed and released by the University of Reading to show the effects of Olive Leaf Extract on both blood pressure and cholesterol, demonstrating the positive effects on the risk factors of cardiovascular disease, according to a paper published this week in the European Journal of Nutrition1.The research is particularly exciting for us at Comvita, as it provides a natural approach to helping manage cardiovascular risk factors and overall health.

The study results showed that average blood pressure, plasma total and LDL-cholesterol and triglycerides were significantly lower after six weeks of Olive Leaf Extract intake compared to those taking a placebo treatment.

The 60 person study featured pre-hypertensive participants who consumed Olive Leaf Extract or a placebo daily for six weeks, and then crossed over to the other treatment arm for a further six weeks. Reduction in diastolic blood pressure is associated with a 6-7% reduction in cardiovascular disease risk and a 10-15% reduction in stroke and heart attack**. The effect of the Olive Leaf Extract on blood pressure may be associated with a 9-14% reduction in cardiovascular disease risk, making it a useful addition to a healthy diet and lifestyle. 

Professor Ian Rowland from the University of Reading said that,

“The results are promising and support a natural approach to helping manage cardiovascular risk factors and overall health. We think this is a significant finding. Cardiovascular disease is the major cause of premature death worldwide, with clear evidence that reducing risk factors like elevated blood pressure and cholesterol can help prevent this disease.”

Researchers have previously shown Olive Leaf Extract has a positive short term impact on cardiovascular risk factors4 but this is the first research to show the beneficial effects are retained over a longer timeframe (six weeks).

The study was conducted using Comvita Olive Leaf Extract, with a dose of 136mg of Olive Leaf extract, the effects of  which can be attained by taking 2 link.
