Olive Leaf Extract

Olive leaf extract comes from the leaves of the olive tree. Olive trees are native to hotter climates including Asia, Africa and the Mediterranean.

One of the main bioactive compounds in olive leaf is Oleuropein, an antioxidant which is used for its therapeutic support as an antibacterial[1], antifungal[2] antiviral[3] and also for cognitive health too. Its use around the health of our immune system is not a new concept and dating back to the 1800s, it was used in a tea format as it was thought to be anti-malarial!

Olive leaf extract is commonly used in the treatment of overgrowth of yeasts such as candida albicans, a fungus that can over-grow in immunocompromised patients and can cause symptoms such as digestive issues and thrush. As an antiviral support, olive leaf extract has shown efficacy against some viruses such as hemorrhagic septicemia rhabdovirus (VHSV), hepatitis B virus (HBV) and human immunodeficiency virus (HIV)[4]. Most commonly as a supplement, it is used for its activity in relation to upper respiratory infection where is has been shown to reduce the duration of infection[5]. Recently, more studies are being conducted to look at oleuropein and its effect on cancer cells as it has been reported to modulate several oncogenic signaling pathways[6] and shows promise in reducing tumors.

Olive leaf extract has also shown to be effective in supporting some cardiovascular biomarkers such as lowering blood pressure and blood lipid levels[7] due to its antioxidant properties.

To receive its immune boosting and cardioprotective support you can find olive leaf extract in a variety of formats but it is commonly taken as a capsule or powdered form supplement.
