Benefits
Cardiovascular support
In a randomized placebo-controlled trial, olive leaf extract supported improvements in cardiovascular health markers, consistent with its heart-health positioning.
Healthy blood pressure
Olive leaf polyphenols are studied for supporting blood pressure already within a healthy range.
Antioxidant and metabolic support
Oleuropein is a strong antioxidant that also supports healthy blood-sugar and lipid markers.
Mechanism of action
Oleuropein activity
Oleuropein and its metabolite hydroxytyrosol support healthy blood-vessel function and antioxidant defense, mechanisms tied to blood-pressure and vascular health.
Nitric-oxide support
Olive polyphenols help maintain the nitric-oxide signaling that keeps blood vessels relaxed and flexible.
Clinical trials
