Olive leaf extract comes from the leaves of the olive tree. It contains an active ingredient called oleuropein. Research suggests that this nutrient contributes anti-inflammatory and antioxidant properties, and that extracts of olive leaves reduce cardiovascular risk, lower blood pressure and eliminate free radicals.

Debene carries CHO-LEVEL a food supplement that offers a natural way to control risks caused by high blood cholesterol. We also carry TENSO-LEVEL, a food supplement based on the patented EFLA-943 molecule, which has been shown to reduce hypertension. Both are based on olive leaf extract.

According to Healthline, the benefits of olive leaf extract are:


Improved Heart Rate

Researchers believe that olive leaf extract can have positive effects on atherosclerosis, or narrowing of the arteries, which is the highest risk factor for heart disease. High levels of LDL, or “bad” cholesterol, and total cholesterol are risk factors for developing this disease.


Lower Blood Pressure

Olive leaf extract may help lower systolic and diastolic blood pressure. A 2017 study found that olive leaf extract successfully lowered blood pressure. A lower blood pressure can reduce your risk of stroke and heart attack.


Better Weight Management

Along with heart-healthy benefits, olive leaf extract could also help with weight loss. A 2014 study researched the effect of olive leaf extract in preventing high-fat, diet-induced obesity. It’s thought that olive leaf extract prevents obesity by regulating the expression of genes that affect weight gain. It may also aid in reducing food intake.


Reduced Cancer Risk

In one cell study, olive leaf extracts were shown to stop cancerous cell growth. Researchers suggest that the extract has strong antioxidant properties, but this is also one of the first studies on olive leaf extracts and their anticancer effects. More research is needed to prove this benefit.


Protection against Alzheimer’s and Parkinson’s

Oleuropein is shown to provide protection against Alzheimer’s disease. Research suggests that the antioxidant effects of olive leaf extract may also help with preventing damage or loss of dopamine neurons that’s associated with Parkinson’s disease.”
