Health Benefits
Although there is currently a lack of clinical trials testing the health effects of olive leaf extract, some preliminary studies have given support to some of the benefits listed above. Here’s a look at some key findings from the available research:
Diabetes
Olive leaf extract may aid in diabetes control, according to a small study published in the Journal of Medicinal Food. For the study, 79 adults with type 2 diabetes took either a supplement containing olive leaf extract or a placebo every day for 14 weeks. By the study’s end, participants given olive leaf extract showed a significantly greater decrease in blood sugar levels compared to members of the control group.
While this study sample size is small, it replicates earlier animal studies and shows promise in the treatment of type 2 diabetes.
High Blood Pressure
Olive leaf extract shows promise in the treatment of hypertension, as is supported by a 2017 study published in the European Journal of Nutrition which found that phenolic-rich olive leaf extract reduces blood pressure.
Researchers gave 60 prehypertensive subjects either olive leaf extract—136 milligrams (mg) oleuropein; 6 mg hydroxytyrosol—or a placebo for six weeks while monitoring blood pressure and found clinically significant reductions in blood pressure, total cholesterol, LDL cholesterol, and inflammatory markers in the treatment group.
While this was a small study, it replicated previous human research and animal studies and shows promise for olive leaf extract as a treatment for high blood pressure.3
Viruses
Olive leaf extract has antiviral properties and is used in holistic medicine to treat certain viruses. In laboratory testing, olive leaf extract was shown to effectively fight herpes, mononucleosis, and rotavirus, and it may also be useful against influenza and HIV.4
While the research is limited to cell cultures and olive leaf extract’s benefits have not been proven human studies, strong anecdotal evidence suggests it can effectively treat cold sores.
Dosage and Preparation
Olive leaves come in capsules, soft gels, and tinctures. There is no recommended daily allowance for olive leaf extract. The standard dose ranges from 500 mg to 1,000 mg daily. Most supplement labels recommend splitting the dose, taking 250 mg to 500 mg two to four times a day with food.

Olive leaf has been shown to improve insulin sensitivity and pancreatic beta-cell function, although the mechanism by which it does so is not fully elucidated. Its effects on lipids and blood pressure are less clear and further research is required to substantiate these claims.
Due to the limited research, it’s too soon to recommend olive leaf extract as a treatment for any condition. It’s also important to note that self-treating a condition and avoiding or delaying standard care may have serious consequences. If you’re considering using olive leaf extract for any health purpose, make sure to consult your physician first.
Therefore, it should not be consumed as an alternative for medicine but as a dietary substitute for extra health benefits.
