Scientists have discovered a unique molecule known as oleuropein, which is found in abundance in the leaves of the olive tree.

Olive leaf extract looks set to become a worldwide, super-star food supplement – and there are a number of good reasons why.

OLE is quite well known for its ability to lower blood pressure.

A human study in 2011 by E Susalit shows OLE actually outperformed catopril, a standard blood pressure medication.

Both oleuropein and catopril decrease the tension and help widen the walls of blood vessels, thus reducing blood pressure.

Hardening of the arteries, called atherosclerosis, occurs when plaques build up in the arterial walls. This can eventually block blood flow and trigger a heart attack or strokes.

OLE appears to reduce the risk of this happening. Found to lower blood sugar, it slows the digestion of starches into simple sugars and studies have shown daily doses of 500mg result in a significant reduction of haemoglobin A1c levels, which is a key blood sugar test.

This causes a significant decrease in insulin-resistance similar to the drug metformin. This is highly significant for anyone with type 2 diabetes or heading in that direction.

Studies show OLE's antioxidant properties help to reduce cancer formation at its earliest stages. They help prevent inflammation, which is a major promoter of tumour growth.

In breast cancer cells, it helps to reduce malignant cells' ability to respond to estrogen, the female hormone many breast cancer cells depend on for their survival.

Arthritis sufferers also appear to gain some benefits from OLE supplementation.

Another key benefit is oleuropein is found in far higher concentrations than in olive oil, so even small doses OLE can be effective.

There are also many positive stories about people outside these studies reporting that they have fewer cold and flu symptoms and other health benefits after using OLE.

Although there appears to be only positive benefits from taking OLE, this comes with a warning you should consult your health professional before making any changes to current prescribed medications.
