Olive leaf extract is a natural source of health with therapeutic properties that:
- gastroprotective (protects the digestive system)
- neuroprotective (protects the central nervous system)
- antimicrobial (inhibits the growth of microorganisms)
- anticancer (reduces the risk of cancer)
- anti-inflammatory (reduces the risk of inflammation)
- antinociceptive (reduces pain stimulants)
- antioxidant (prevents oxidation or cell damage)
These properties mean that olive leaf extract can help to lose weight, heart health and herpes break. Read on to find out how olive leaf extract can benefit you, your dosage information, and more.

How will olive leaf extract benefit you?
Olive leaf extract comes from the leaves of an olive plant. It contains an active substance called. This nutrient is thought to contribute to the anti-inflammatory and antioxidant properties of the olive leaf extract.
You may have heard how the Mediterranean diet is linked to a decline in chronic diseases, especially cardiovascular disease. This is thought to be due to the focus on olive oil, leaves and fruits in the diet. It has been used as a traditional medicine for centuries in countries such as Greece, Morocco and Tunisia.
Here are researches about the greatest reported benefits of olive leaf extract.
To treat cold sores with olive leaf extract, drip 1-2 drops onto the cotton ball and place on the throat. One study found that the antiviral and antimicrobial factors of olive leaf extract reduce the ability to invade cells around the herpes virus.
Protects the brain against Alzheimer’s and Parkinson’s
Oleuropein has also been shown to provide protection against Alzheimer’s disease. The antioxidant effects of olive leaf extract can also help prevent damage or loss of dopamine neurons that accompany Parkinson’s disease.
Improves heart health
Researchers believe that olive leaf extract can have positive effects on the narrowing of the arteries, the highest risk factor for atherosclerosis or heart disease. High levels of LDL or “bad” cholesterol and total cholesterol are risk factors for the development of this disease. In an animal study conducted in 2015, the effects of olive leaf extract on cholesterol levels were evaluated. Rats receiving extract for eight weeks significantly reduced their cholesterol levels.
Lowers blood pressure
Olive leaf extract can help lower systolic and diastolic blood pressure. A 2017 study found that olive leaf extract successfully reduces blood pressure. Low blood pressure can reduce the risk of stroke and heart attack.
Treatment of type 2 diabetes
One review found that olive leaf extract and type 2 diabetes can help improve insulin secretion in these olive leaf oil extract cells. Animal studies have shown that olive leaf extract can:
- reduce hyperglycemia
- reduce hyperinsulinemia (too much insulin in the blood)
- Reduces blood sugar, plasma malondialdehyde and other signs of oxidative stress (imbalance of free radicals that can harm the body)
- reduce cholesterol
- reduce serum glucose
- increase serum insulin
However, further studies are needed to test olive leaf extract in humans. A human study found that people taking olive leaf extract tablets lower their average blood sugar levels and fasting plasma insulin levels. However, insulin levels after meals were not significantly affected.
Supports weight management
In addition to cardiovascular health benefits and type 2 diabetes protection, it means that olive leaf extract can help in weight loss. An animal study conducted in 2014 investigated the effect of olive leaf extract on preventing high-fat, dietary-induced obesity. Olive leaf extract is thought to prevent obesity by regulating the expression of genes affecting weight gain. It can also help in reducing food intake.
Reduces cancer risk
A cell study in which olive leaf extracts have been shown to inhibit cancer cell growth. Researchers argue that the extract has strong antioxidant properties, but this is also one of the first studies on olive leaf extracts and their anticancer effects. Further research is needed to prove this benefit.
