The Effect of Olive Leaf Extract

Olive leaf extract due to its high content of polyphenols can help people with hypertension lower their systolic and diastolic blood pressure.

Hypertension

Research done in animal models in 2002 showed that olive leaf extract can quickly and consistently lower blood pressure. The extract potentially affects compounds that regulate the diameter of the arterial walls. (1)

Another similar study in 2012 showed the hypotensive effects of olive leaf extract on animal models. (2)

A double-blind clinical trial conducted in 2011 with patients who had first-line hypertension found that the olive leaf extract was as effective as a commonly used antihypertensive drug. After 8 weeks of daily intake of 500mg of olive leaf extract, systolic blood pressure had fallen by approximately 11.5 mmHg and diastolic by 4.8 mmHg. (3)

In 2017 another study was conducted that also found the antihypertensive effect of olive leaf extract. In a randomized, double-blind trial, taking olive leaf extract with 136 mg of oleuropein and 6 mg of hydroxytyrosol helped to lower blood pressure and inflammation. (4)

Chain Benefits

Along with the decrease in blood pressure, a decrease in triglyceride levels was observed. These two factors, in turn, help reduce the risk of atherosclerosis, heart attack, stroke and heart disease. (3)

By making the extract part of a healthy diet and lifestyle, eating it daily can lead to a moderate but significant reduction in many cardiovascular risks.

Interactions

Despite the many benefits we should be reminded of the following.

For people with low blood pressure the extract may lower it even further.

The extract may also interact competitively or cooperatively with medication taken to lower blood pressure or control diabetes. Patients should therefore always consult their physician to avoid or regulate interactions.
