What is Olive Leaf Extract?

Olive leaves and olives come from the olive tree (Olea europaea L.), which grows mainly in the Mediterranean area and warm climates.

Olive leaves are silvery green and grow up to 10 cm (3.9 in) in length. Olive leaves are harvested and dried before being crushed into powder or soaked to extract their medicinal compounds.

Olive leaf extract contains many polyphenolic compounds that have an antioxidant effect. The main phenolic antioxidants in olive leaf extract are hydroxytyrosol, oleuropein and luteolin-glucoside.

Researchers have found that using hot water or ethanol brings out a compound called hydroxytyrosol which has antioxidant and anti-inflammatory properties. Oleuropein is the main active component from olive leaf extract. Scientific research has also revealed that oleuropein and hydroxytyrosol are easily absorbed in the body.

Olive leaf extract vs. olive oil

Interestingly, olive leaf extract has more antioxidant potential than olive oil. Studies have shown that the phenolic compounds in olive leaf extract are more potent and in higher concentration than olive oil.

In fact, olive leaf extract can be added to virgin olive oil to increase the antioxidant properties in olive oil.

Benefits of Olive Leaf Extract

The benefits of olive leaf extract are mainly due to its antioxidant compounds like oleuropein, apigenin-7-glucoside, luteolin-7-glucoside, and hydroxytyrosol. Let’s look in more detail how these chemicals make olive leaf good for lowering risk of cardiovascular disease and many more ailments.

Olive leaves have traditionally been used to enhance the functioning of the immune system and enhance the body’s efforts to fight invading organisms.

Because of its antiviral properties, some people use olive leaf extract to treat viral diseases such as the cold or flu.

Olive Leaf Extract Helps to Lower Blood Pressure

Taking olive leaf supplements can help to lower blood pressure due to the high content of polyphenols.

Research carried out in 2017 found that olive leaf extract has an antihypertensive effect. In one randomized, double-blind trial, taking olive leaf supplements with 136 mg oleuropein and 6 mg hydroxytyrosol helped to reduce blood pressure and inflammation.

In another trial, taking 500 mg olive leaf extract for high blood pressure was just as effective as Captopril. This is a popular drug to treat hypertension (high blood pressure). After 8 weeks of olive leaf extract therapy, systolic blood pressure had dropped by around 11.5 mmHg and diastolic by 4.8 mmHg.

Compounds in Olive Leaf Extract Boost Heart Health

Research has shown that the therapeutic effect of oleuropein and hydroxytyrosol (found in olive leaf extract) has a protective effect on the heart. This strengthens the heart muscle to keep the heart healthy.

Oleuropein in olive extracts also increases the amount of nitric oxide. Nitric oxide helps to increase blood flow and reduce blood pressure. It was found that the effect of olive leaf extracts has an anti-inflammatory effect on the cardiovascular system.

A review of studies reported that the oleuropein in olive leaf extract has cardio protective properties.

Olive Leaf Extracts Help Kill Off Parasites

Olive leaf extracts help to fight certain parasitic diseases naturally.

The high number of phenolic compounds in olive leaf extract have a toxic effect on some parasites like the Leishmania major. This parasitic infection causes leishmaniasis that can result in skin ulcers and infections.

One study in 2017 found that olive leaf extracts have an antiparasitic effect. After 4 weeks of treatment, signs of leishmaniasis were gone. The researchers reported that the phenolic compounds in olive leaf extract have a remarkable effect in treating L. major infections.

Researchers also noticed that in an 8-week period of olive leaf supplementation, blood glucose levels stabilized and lipid blood levels were reduced.

Extracts from Olive Leaves Can Help You Lose Weight

Olive leaf extract could help weight loss because it helps to boost your body’s metabolism and break down blood fat.

Olive leaf extract can also reduce the negative effect that obesity has on the body.

In a study on humans using liquid olive leaf extract, scientists found that olive extract improves insulin sensitivity and reduce blood pressure in overweight adults. Participants took 20mL olive leaf extract daily. At the end of the trial, it was noted that inflammatory markers related to obesity were reduced.

Another study found that taking a natural product containing citrus fruit extract and olive leaf extract helped to improve fat metabolism.

Research on mice found that supplementing their diet with olive leaf extracts had an anti-obesity effect. Two groups of mice were fed a high-fat diet. The mice that were fed olive leaf extract experienced less weight gain than the mice who didn’t have the leaf extract.

Olive Leaf Extract Positively Affects Brain Function

The ability of compounds in the olive leaf extract to kill off free radicals means that you can take olive leaf supplements to boost cognitive power.

A review of the medicinal benefits of olive leaf extracts found that oleuropein has a neuroprotective effect. Many studies have shown that the antioxidant properties of oleuropein can help prevent or slow down cognitive disorders like Alzheimer’s disease and dementia.

Olive Leaf Extract Can Strengthen Bones

Polyphenols in olive leaf extracts can help to prevent osteoporosis and help reduce pain and inflammation in joints.

Research has uncovered that compounds in olive leaf extract like hydroxytyrosol, tyrosol, and oleuropein have an anti-inflammatory effect. In one clinical trial, olive extracts helped to prevent the decline of bone density. The anti-inflammatory effect of olive extracts helped to increase calcium absorption. Other studies have shown that oleuropein helps to preserve bone marrow.

The researchers mentioned that supplementing the diet with olive oil or olive leaf extract can help to prevent osteoporosis in menopausal women.

Antioxidant Effect of Olive Leaf Extract Can Help Prevent Cancer

Taking olive leaf supplements can provide plenty of antioxidants that can help prevent the development of certain cancers.

A review of studies into the use of olive leaf extracts in treating cancer has shown positive results. For example, because olive leaf extracts have a higher concentration of polyphenols, they could have a great potential in cancer therapy. Researchers also found that olive leaf extracts contain anticancer compounds (luteolin and apigenin) which are not found in olive oil.

Clinical trials have demonstrated that the strong antioxidant effect of olive leaf extracts could prevent or reduce cancers such as pancreatic cancer, breast cancer, prostate cancer, colorectal cancer, and leukaemia.

Of course, more research has to be done on ways to use olive leaf extracts to treat cancer. However, many studies point to the fact that extracts from olive leaves contain powerful antioxidants that have anticancer properties.

How to Select the Best Olive Leaf Extract

When looking to buy the best olive leaf extract supplement, it is important to look for high-quality products.

The best supplements containing extracts of olive leaves should state the amount of oleuropein in each capsule. Some super-strength olive leaf extracts contain up to 25% oleuropein. Good olive leaf supplements also state the amount of hydroxytyrosol.

You should also make sure that there are no cheap fillers or other unnecessary ingredients in the olive leaf supplement.

Olive leaf can be purchased as an extract in health stores or online. You can purchase olive leaf extract in a liquid form like this one or as a dried powder in capsules like this one. Always make sure the extract was made from organic olive leaves to make sure it’s pesticide free.
