This claim can only be used for olive oils which contain at least 5 mg of hydroxytyrosol and its derivatives (eg oleuropein and tyrosol complex) per 20 g of olive oil. Olive oil phenols help protect blood lipids from oxidative stress and to achieve this beneficial effect the consumer should consume daily 20 grams (2-3 tablespoons) of high phenolic olive oil.
These olive oils are considered a dietary supplement and due to their high content of phenols, they have a more bitter and spicy taste than all the others. It is recommended to consume them raw.
