Acai is a Brazilian superberry reknowned for it's incredible antioxidant properties and for being the berry of choice of Oprah Winfrey. Why? because apparantly it also has special 'weight-loss' powers. We love to enrich our dark chocolate with acai as we know how much goodness is in there. The whole bar contains four times the amount of antioxidants many nutritionists believe we should get in a day!
