Supporting the Immune System

Perhaps one of the most well-known benefits of olive leaf extract is its ability to support the immune system. Olive leaf extract is a common ingredient in many immunity boosters on the market, and for good reason. 

It’s anti-inflammatory properties help to modulate the immune response and support normal immune response pathways, while its antioxidant properties (thanks to its polyphenols) are able to combat the effects of oxidative stress and free radicals.

Olive leaf extract can support your metabolism by providing some semblance of appetite control. This could also lead to weight management and weight loss support when paired with diet and exercise. 

Supporting Heart Health

Olive leaf extract has been researched and studied to show a significant improvement in LDL cholesterol levels. It does seem that a fairly high dosage of olive leaf extract is needed to be most effective in these circumstances. 

Olive leaf extract is used in some blood pressure medications that require a prescription. There are direct benefits to lowering systolic and diastolic blood pressure. 

With the support it provides in maintaining healthy cholesterol and blood pressure, olive leaf extract supports overall heart health.

While there is substantial research that shows a lot of positive qualities of the use of olive leaf extract, keep in mind that clinical studies are limited. Most of the health benefits are primarily related to immune support, heart health, and anti-inflammatory benefits.

It may take some work to determine an appropriate dosage if you’re not taking it as an ingredient in a multi-herbal supplement. 

Olive Leaf Extract Side Effects

  • Nausea
  • Stomach pain
  • Respiratory allergic reactions from pollen triggers

The notated respiratory allergic reactions are primarily related to allergies to pollen from plants within the same family as the olive plant. This includes ash trees, lilac, jasmine, privets, and forsythia. 

If you experience any discomfort or side effects when using olive leaf extract, it is best to stop usage and consult with your medical provider. 


In conclusion, olive leaf extract has a myriad of health benefits that can help in many positive ways. The benefits of this supplement can maintain immune support but it also has other possible benefits for your heart and overall health. which widens the benefit margin overall.
