In Mediterranean countries, oil production plays a special role and is an important part of the culture. Olives from the olive tree are essential for the production of oil, but they are not the only ones that are such valuable raw materials. Equally valuable are the olive leaves with their characteristic grey-green colour. The leaves and the extracts extracted from them are used in the production of dietary supplements. A product worth checking out is Swanson Olive Leaf Extract, 750mg in swallowable capsules. It contains olive leaf extract (standardised to 20% oleuropein content).

Oleuropein - the main component of olive leaf extract

Oleuropein, which belongs to the polyphenol group, is considered to be one of the most important active compounds found in olive leaf extract. It is attributed with numerous interesting properties. It is worth remembering that high-quality olive oil can also become a source of polyphenols in the daily diet - the polyphenols in olive oil help protect blood lipids from oxidative stress.
