Olive Leaf Extract – What is it?

Olive trees, scientifically known as Olea europaea, have been used since centuries for its fruits, oils and leaves. The various parts of these trees are used in traditional medicine as it has numerous therapeutic properties. Olive leaf extract (OLE) is obtained from the leaves of olive trees that has been under extensive scientific research and studies. In the article below, we will discuss the scientifically proven health benefits and uses of olive leaf extract.

What is the composition of Olive Leaf Extract?

The primary active constituents of olive leaf extract are polyphenols. The polyphenols in olive leaf extract include oleuropein and hydroxytyrosol that are the main compounds involved in giving the promised health benefits.

Oleuropein is the most abundant compound in the leaves of olive trees that gives most of the benefits attributed to olive leaf extract. Olive leaf extract also contains flavonoids and triterpenes that acts as antioxidants and alleviate the oxidative stress from the body.

What are the Health Benefits of Olive Leaf Extract?

Olive leaf extract is a concentrated source of essential nutrients, antioxidant, anti-inflammatory and antimicrobial chemical constituents. These attributes of olive leaf extracts grant many health benefits to individuals consuming it in routine. Enlisted below are the health benefits of olive leaf extracts (OLE).

1. Antioxidant Properties

It is one of the most well-known and documented benefit of olive leaf extract. Antioxidants are chemical compounds that relieves the oxidative stress by combatting against the toxic free radicals released by the metabolic reactions at the cellular level. Free radicals are unstable ions that the body’s metabolic reactions produce in response to pressures, such as those by environmental influences. Free radicals contribute to inflammation, aging and chronic diseases.

Various research has shown that the polyphenols in olive leaf extract can exert significant antioxidant effects. These antioxidants, such as oleuropein and hydroxytyrosol reduces the risk of oxidative damages and resultant chronic diseases by inhibiting the production and accumulation of toxic free radicals.

To achieve antioxidant effects of olive leaf extract, ensure regular intake of Olive Leaf Extract supplements.

2. Anti-inflammatory Properties

Chronic underlying inflammation is the main contributor to serious health conditions such as arthritis, heart diseases, cancers and neurodegenerative disorders. The anti-inflammatory properties in the constituents of olive leaf extract provides remarkable benefits against chronic inflammatory states. Various research can confirm this by suggesting that oleuropein is the main constituent in olive leaf extract that inhibits the production of pro-inflammatory cytokines and enzymes to reduce the inflammation in the body.  

A study article published in the Life Sciences journal demonstrated the role of oleuropein in reducing inflammation in a rat model with arthritis. This research demonstrated and suggested the likely possibility of olive leaf extract to manage and relieve chronic 0inflammations in human subjects as well.

3. Cardiovascular Support

Cardiovascular disorders are currently the leading causes of deaths all over the world. Olive leaf extract has been proven by various research and studies that it may have beneficial effects on the cardiovascular health of an individual. The antioxidant and anti-inflammatory properties of the olive leaf extract protects the heart health from potential damages and exhaustion.

Studies have shown that olive leaf extract reduces the blood pressure by improving the arterial function and lowers the blood cholesterol levels as well. A study article published in the Phytotherapy Research journal discovered and discussed that olive leaf extract supplementation have the potential to reduce both systolic and diastolic blood pressures in patients with Stage I hypertension.

Moreover, oleuropein in the olive leaf extract has shown benefits in terms of lowering the blood cholesterol levels by promoting the oxidation of low-density lipoproteins (LDL – the bad cholesterol). As the levels of LDL drops in the blood, the risk of atherosclerosis and cardiovascular ailments decreases as well.

4. Antimicrobial Properties

Olive leaf extract contains potent antimicrobial chemical constituents that makes it an effective natural supplement against harmful pathogens that often finds a way to enter the body. Olive leaf extract can protect against pathogens such as bacteria, viruses and fungi that cause multiple infections and illnesses in the body.

Various studies report that oleuropein in olive leaf extract can inhibit the growth and invasion of harmful pathogens (bacteria and fungi) that often cause severe infections, including Staphylococcus aureus, Escherichia coli and Candida albicans. Moreover, other research articles also suggests that the antiviral properties of olive leaf extract inhibit the replication of viruses as well such as H. influenza and herpes simplex viruses (HSV).

5. Controls Blood Sugar Levels

Diabetes mellitus is a chronic health condition tat occurs due to deteriorated metabolism and reduced insulin intake by the end organs. Diabetic individuals experience high blood sugar levels that damage the end organs and cause its dysfunction with the passage of time. Olive leaf extract has certain chemical constituents that promises the management of both diabetes and its chronic complications. The polyphenols in olive leaf extract mediates the glucose metabolism and increases the insulin sensitivity.

A study article published in the Journal of Medicinal Foods demonstrated the significant role of olive leaf extract in regulating the blood sugar levels of diabetic rats, along with enhancing their insulin sensitivity. Research involving human participants have also shown positive outcomes such as a randomized controlled clinical trial published in the journal Phytotherapy Research have shown increased insulin sensitivity in middle-aged overweight men.

6. Neuroprotective Properties

Neuronal cells are often prone to oxidation and exhaustion that leads to neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease. The antioxidant and anti-inflammatory properties of olive leaf extract provides neuroprotective benefits that improve memory and prevent cognitive decline.

Various research has demonstrated that the polyphenols in olive leaf extract, particularly oleuropein, provides protection to the neuronal cells from oxidative damage, formation and deposition of amyloid plaques in the neuronal cells and tissues. Moreover, experiments involving animal models have shown that olive leaf extract increases memory and concentration. Similar effects are highly likely for humans as well to improve cognition and protect from neurodegenerative disorders.  

7. Better Skin

Olive leaf extract is often used in skincare products for its antioxidant, anti-inflammatory and antimicrobial properties. These attributes help in skin protection and guarding from various external damages, underlying inflammation and skin infections.

A study article published in the Pharmaceutical Biology journal highlighted the role of oleuropein and hydroxytyrosol in wound healing and reducing inflammation in a mouse model. Moreover, the antioxidants in olive leaf extract ensures skin protection against the ultraviolet rays (UV radiations) that reduces the risk of sunburns, premature aging and skin cancer.
