Olive oil extract (hydroxytyrosol)

Tier 2 — promising · Cardiovascular · Antioxidant

Hydroxytyrosol is the main antioxidant in extra virgin olive oil and one of the most potent natural antioxidants studied. EFSA approved a health claim for olive oil polyphenols protecting blood lipids from oxidation. Supplement evidence is more limited than dietary olive oil evidence. Simply using extra virgin olive oil in cooking may be equally effective.

Dose: 5–20 mg/day hydroxytyrosol; EFSA claim requires 5 mg/day from olive oil or extracts
