Polyphenol extract with antimicrobial and cardiovascular supporting properties
We rank Olive Leaf Extract by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Olive Leaf Extract is a supplement made from the leaves of the olive tree. It contains polyphenols, which are natural compounds found in plants that act as antioxidants to protect cells from damage.
It is primarily used for two main reasons:
The process begins by harvesting olive leaves, which are then dried and crushed. A solvent is used to pull the active polyphenols out of the plant material. This liquid is then concentrated and dried into a powder, which is either put into capsules or mixed into other supplements.
This ingredient is generally mid-range in price. This is because the extraction process requires specific equipment to isolate the polyphenols, and the cost of sourcing high-quality olive leaves varies depending on the region and harvest.
