What is Olive Leaf Extract?

You have heard of it and you most likely know someone who swears by it, but what exactly is Olive Leaf Extract?

Olive Leaf Extract is a supplement produced from olive leaves and no, it is not the same as olive oil!  Olive Leaf Extract contains the healthy compounds found within an olive leaf – and it is used as a traditional herbal remedy for general health and wellbeing. Olive oil on the other hand, comes from the olive fruit itself. Olive oil is the fresh juice of the olive fruit and is a commonly used fat or oil in the diet.

A quality olive leaf extract will be made from fresh olive leaves that have been well looked after in the perfect, Mediterranean style climate. Did you know that Victoria, Australia has a similar climate to parts of the Mediterranean?



Like any herbal supplement you buy, it’s the quality and source of the natural ingredient that really matters. The type of leaves used to make olive leaf extract can either be fresh or dry. Using fresh leaves, that means leaves taken straight from the olive tree with no further drying, will result in an olive leaf extract with a unique antioxidant profile that is highly representative of the natural profile found in the olive leaf. Wellgrove Olive Leaf Extract uses only fresh olive leaves sourced from Cobram Estate’s olive groves. The leaves are processed within 6 hours of being picked from the olive trees, without the use of chemicals, alcohol solvents or excessive heat. Some olive leaf extract products are made from dry leaves (check the front of the label to find out). Dry leaf products typically contain lower levels of overall antioxidant.1



The wide variety of healthy antioxidants found in olive leaf extract is a good reason why you should take it. Our bodies need antioxidants to help reduce and remove potentially harmful toxins. Antioxidants are well known to help support our bodies immune and cardiovascular system.2,3 Olive leaf extracts will contain varying amounts of antioxidants.

Traditional evidence shows that olive leaf extract may help relieve symptoms of common colds and flu and overall help support immune health*. At a higher strength of antioxidants (oleuropein and hydroxytyrosol), olive leaf extract helps support cardiovascular health.
