Benefits
Cardiovascular support
Olive polyphenols such as oleuropein and hydroxytyrosol are studied for supporting healthy blood pressure and blood-vessel function.
Antioxidant defense
Hydroxytyrosol and oleuropein are powerful antioxidants that protect cells and LDL cholesterol from oxidation.
Metabolic support
Olive polyphenols are studied for supporting healthy blood-sugar and lipid markers.
Mechanism of action
Olive polyphenol action
Oleuropein and hydroxytyrosol support nitric-oxide-mediated blood-vessel relaxation and antioxidant defense.
Anti-inflammatory action
Olive polyphenols calm oxidative and inflammatory stress in blood vessels and tissues.
Clinical trials
