The term “high-phenolic” should be used for olive oils with phenolic content > 500 mg/kg. Using the measured average loss rate, we conclude that an olive oil with phenolic content > 500 mg/kg will retain the health claim limit (250 mg/kg) for at least 12 months after bottling. The term exceptionally high phenolic olive oil should be used for olive oil with phenolic content > 1200 mg/kg (top 5%).

High Phenolic Olive Oils are those Olive Oils that contain a high percentage of phenolic compounds and are directly related to the health benefits of olive oil. According to the EU Health Claim Labeling Regulation (432/2012), the claim may be used only for olive oil which contains at least 5mg of hydroxytyrosol and its derivatives (e.g. oleuropein complex and tyrosol) per 20g of olive oil.
The beneficial effect for the consumers is obtained with a daily intake of 20g of olive oil (2-3tbs). This daily intake of high phenolic olive oil contributes to the protection of blood lipids from oxidative stress. UC Davis, Harvard University, and many other research centers in the world embrace this idea and have backed it up with many kinds of research over the last ten years.
