2024's Top 9 Olive Leaf Supplements

Find out what to look for in a quality Olive Leaf supplement and what to watch out for

What is Olive Leaf?

Olive leaf extract is just what it says on the tin. Whereas olive oil is taken from the olive itself, olive leaf extract is taken from the leaves of the olive tree. Olive leaf extract contains many of the same chemical properties as olive oil and delivers many of the same benefits.

Olive derivatives have been a staple of Mediterranean cultures for thousands of years. Olive oil is a crucial component of the Mediterranean diet, and traditional medicines in this region often include the use of olive leaves.

Is it any coincidence that people from Mediterranean cultures exhibit lower rates of heart disease and cancer than people from other parts of the world? The Mediterranean way of life is so beneficial that the Mediterranean diet is one of only 3 diets on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.

Read on to find out more about what olive leaf extract can do for you.

Olive Leaf Extract Is Nutrient Rich

Olive leaf extract contains high levels of the polyphenol, oleuropein. Oleuropein is thought to be the cause of many health benefits associated with olive oil consumption, but not many people know that olive leaf extract actually contains higher concentrations of oleuropein than even extra virgin olive oil.

Oleuropein is a powerful antioxidant, and it also possesses well-documented antimicrobial and antiviral properties. As far as natural molecules are concerned, oleuropein is as good as it gets.

Olive leaf extract also contains high levels of important phytonutrients such as flavonoids and catechins which raise its antioxidant capacity above that of other popular supplements such as vitamin C and green tea extract.

Benefits of Olive Leaf Extract

  • Decreased inflammation

Flavonoids and phenols like the ones found in olive leaf extract have been shown to have anti-inflammatory properties, likely due to their antioxidant properties.

  • Reduced risk of heart disease

Olive leaf extract’s high concentration of oleuropein lends it the ability to dilate the blood vessels, lowering blood pressure and improving circulation. Research also suggests that oleuropein may reduce blood clotting.

  • Antibacterial and antiviral activity

Wild olive trees produce oleuropein as a way to fight bacteria and mold, and research suggests those same properties are passed along to you when you take olive leaf extract. Olive leaf extract may even provide a useful treatment for cold sores from herpes.

  • Improved immunity

One study involving athletes found that over the course of the study, participants given regular doses of olive leaf extract saw a 28% reduction in sick days compared to those given a placebo.

This study primarily focused on symptoms of upper respiratory illnesses such as sore throat, coughing, sneezing, and the common cold.

  • Protection against neural degradation

Recent research has shown that there is reason to believe that olive leaf extract may possess neuroprotective properties. By bonding with a certain molecule, oleuropein may be able to slow the progression of neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

Potential Side Effects

Olive leaf extract is generally considered to be safe, however you may want to check with your doctor if you take any medication for blood pressure or if you have diabetes.
