Olive Leaf Extract liquid supplements have been used for centuries as a natural supplement

Olive Leaf Extract, Olea europaea, the olive tree, is native to the Mediterranean and has been known for general health and immune support since ancient times

The Egyptians used Olive Leaf Extract for their royalty

Ancient Egyptians used olive leaf extract medicinally and in the process of mummifying royalty, and other cultures including the Greeks employed olive leaf extract as a folk remedy for fever.

Natural Olive Leaf Extract supplements are mentioned in ancient religious texts

Olive Leaf is the first botanical noted in the Bible, where it is described in Ezekiel 47:12, “The fruit thereof shall be for meat, and the leaf thereof for medicine.” Its is also noted in the Koran.

In the 1800s Olive Leaf Extract was used to treat fever and malaria

The first mention of Olive Leaf Extract's medicinal use in modern times was in 1843 when Daniel Hanbury of England reported a bitter substance from olive leaf tea was the agent responsible for successful immune support - healing malaria and associated fevers.

These Olive Leaf Extract findings were reported in 1854 in the Pharmaceutical Journal, along with dosing instructions and a recipe for making the curative tea. In 1898, a strong decoction of olive leaves forming olive leaf extract was cited in King’s American Dispensatory as helpful in regulating body temperature. These were possibly the first formally recorded modern olive leaf liquid supplement recipes.

More recent research points to olive leaf extract immune supplements being antimicrobial, hypoglycemic and having cardiovascular benefits

The Alternative Medicine Review Volume 14, Number 1 2009 reports that in the last century, olive leaf extracts have been studied in both animals and humans and have been found to exhibit strong antimicrobial properties against viruses, bacteria, yeast, and parasites, therefore improving immune support. Olive leaf extract immune supplements also have numerous cardiovascular benefits, some hypoglycemic activity, and possesses antioxidant activity.

So what’s in olive leaf extract that makes it such a great immune supplement and why is the leaf so important?

It's all about the active polyphenols in olive leaf extract that are believed to be responsible for many of the therapeutic properties and are at the core of the healthy Mediterranean diet

The primary olive leaf extract constituents are:

    • mainly secoiridoids (oleuropein and its derivatives)
    • hydroxytyrosol,
    • polyphenols (verbascoside, apigenin-7-glucoside, and luteolin-7-glucoside)
    • triterpenes including oleanolic acid
    • flavonoids (rutin and diosmin).

These constituents afford the tree and its fruits and leaves resistance to damage from pathogens and insects. The primary constituent, oleuropein, first isolated in 1908, is believed to be responsible for many of the therapeutic and natural wellness properties of olive leaf extracts.

But it's the leaf that’s really important relative to other parts of the tree, having up to 40 times more phenolic compounds than olive oil and none of the fats:

Although the active polyphenols are present in the olive fruit and oil, content in the leaf used to make OVIO Olive Leaf Extract is significantly higher than in other parts of the tree.

Of all olive products extra-virgin (acidity <1%) olive oil and olive leaf extract are considered superior sources of phenols and antioxidants. When comparing olive oil and olive leaf extract it is the olive leaf extract that contains far greater concentrations of phenolic compounds – up to 40 times more according to recent research. On top of this, olive leaf extract has the advantage of providing greater antioxidant levels without the high fat content of extra-virgin olive oil.

So Olive Leaf Extract is really amazing, that’s why OVIO has Olive Leaf Extract as the basis of its products

Olive Oil health claims are approved

What can we say about Olive Leaf Extract? European Food Safety Agency (EFSA) has approved Olive Oil health claims

The EFSA has refused hundreds if not thousands of herbal and medicinal claims on health foods.

However in the EFSA Journal 2011;9(4):2033  the agency approved certain claims relating to the olive oil key active ingredients Hydroxytyrosol and Oleuropein (which are found in olive leaf extract):

"it protects body cells and Low Density Lipoproteins (LDL) from oxidative damages"

When referring to protecting low-density lipoproteins (LDL) particles from oxidative damage it noted that 5 mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) in olive oil should be consumed daily.

These amounts, if provided by moderate amounts of olive oil can be consumed in the context of a balanced diet.

Olive Leaf Extract is another excellent source of these protective actives. That's why OVIO uses organic olive leaf as the basis of its products.

It’s the overwhelming combination of centuries of history, approved claims and positive independent research findings that convinced OVIO that Olive Leaf Extract is an incredible ingredient for natural supplements. We are bringing this lesser known ingredient to you through our products.
