150–500 mg/day of olive extract standardized to polyphenols. EFSA health claim requires 5 mg/day hydroxytyrosol (or equivalent from olive products). RCTs for blood pressure used 500–1000 mg/day leaf extract.
About Olive Polyphenols
Contains hydroxytyrosol, oleuropein, and tyrosol as key bioactives. Hydroxytyrosol has a unique distinction: EFSA approved a health claim that 5 mg/day from olive products protects blood lipids from oxidative damage (Regulation EU 432/2012). Multiple RCTs show olive leaf extract (500–1000 mg/day) modestly reduces blood pressure in pre-hypertensive subjects. Oleuropein has anti-inflammatory and antimicrobial properties demonstrated in vitro and small human trials. Fruit and leaf extracts differ in polyphenol profiles — leaf is richer in oleuropein, fruit is richer in hydroxytyrosol.
