Benefits
Protects LDL cholesterol
Olive polyphenols at about 5 mg of hydroxytyrosol per day help protect LDL (bad) cholesterol from oxidative damage, the basis of the approved EFSA olive-polyphenol health claim.
Cardiovascular support
By protecting blood lipids and supporting blood-vessel health, olive polyphenols support cardiovascular wellness.
Antioxidant defense
Hydroxytyrosol is a well-studied olive polyphenol antioxidant that helps protect cells from oxidative stress.
Mechanism of action
Lipid protection
Hydroxytyrosol embeds with LDL particles and shields their fats from oxidation, a key step in keeping arteries healthy.
Free-radical scavenging
Hydroxytyrosol's structure makes it an effective scavenger of free radicals in laboratory studies.
Clinical trials
Randomized placebo-controlled trial of olive LEAF extract — standardized to oleuropein, a different polyphenol than the hydroxytyrosol in elaVida — on cardiovascular health markers. (Stevens et al. 2021, European Journal of Nutrition)
Adults.
This trial tested olive leaf extract (oleuropein), a different polyphenol than the hydroxytyrosol in elaVida. The regulatory basis for elaVida's LDL claim is the approved EFSA olive-polyphenol health claim (5 mg hydroxytyrosol per day helps protect blood lipids from oxidative stress), not this study.
