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.
What Olive Polyphenols supports
- EFSA-approved claim: protects blood lipids from oxidative damage (5mg/day hydroxytyrosol)
- RCTs show modest blood pressure reduction with leaf extract
How much Olive Polyphenols to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
150–500
mg
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.
Clinical evidence
Moderate clinical evidence. EFSA-approved health claim for hydroxytyrosol at 5mg/day; multiple RCTs for blood pressure with leaf extract — stronger evidence base than most herbal extracts
