Studies show that people who eat a diet rich in polyphenols — who consume more than 650 milligrams per day — have a lower risk of death than those who consume less than 500 milligrams per day.
There is currently no recommended daily dose. Several sources recommend 500 to 1000mg of polyphenols per day.
Olive oil, 60mg polyphenols per 100g 
Brussels sprouts, 257mg polyphenols per 100g 
Black Elderberry, 1300mg polyphenols per 100g 
Olive leaf, 10 800mg polyphenols per 100g
