WHAT IT DOES
The Mediterranean diet's MVP, now in your supplement capsule. Provides healthy fats plus bonus polyphenols.
🏆
2
DOES IT WORK?
Excellent oil, but in capsule amounts you won't get the full Mediterranean diet benefits. EVOO contains oleic acid, hydroxytyrosol, and oleocanthal with real anti-inflammatory properties. As a carrier oil in supplements, it helps absorb fat-soluble nutrients and adds some polyphenol bonus. But a tablespoon on your salad does more.
