Callebaut suggests 8 grams of the Anticoa chocolate per day provides 100% of the daily recommended values of antioxidants. It's vegan-friendly as well. I haven't tried it yet but since the chocolate is over 60%, it is a bittersweet chocolate with a nice snap. And would probably make an easy and sweet way to take an antioxidant supplement each day.
