How Olive Helps Improve Immune Health

How Olive Helps Improve Immune Health

Olive leaf is the leaf from the olive tree (Olea europaea) that is native to the area around the Mediterranean.

Oleuropein from olive leaf extract has antimicrobial and antiviral properties.1

In a 2010 study published in the Journal of Pharmacy and Pharmacology, researchers found that hydroxytyrosol and oleuropein both have broad antimicrobial activity against several different strains of bacteria. They claim olive is a potential source of promising antimicrobial agents for the treatment of respiratory tract infections.2

In a 2019 clinical trial on olive leaf extract and upper respiratory illness, researchers found that olive leaf decreased the average duration of illness and decreased sick days in the participants.3

Another study found that olive leaf extract is able to modulate human immune response and increase numbers of immune cells such as natural killer and T helper cells.4


Olive leaf can help benefit immunity through modulating the immune system in addition to exerting antimicrobial and antiviral activity.

In addition to olive leaf, there are several other nutrients and herbs which have been shown to positively affect immune health and function. We combined them into one simple formula called Immune Support by Beyond Vita®.*
