The label says the bar has soy lecithin, so it's not quite so simple as most simplicity bars. But it had that distinctive single origin/simplicity taste I complained about last week, particularly the lingering bitterness. But for some reason, this bar really worked for me more than most of the others. Maybe that "some reason" is my otherwise chocolate-free existence in this caffeine free month. Or maybe soy lecithin is the one additive you should put in your simplicity bar to make me happy.
