We wanted to keep it simple for our patients to get "complete nutrition," yet we also wanted to satisfy different opinions about what "tastes amazing!" We also wanted vegan options for those who are dairy-free. So we came up with six very distinctive Zing bars that give the most choice in just a few flavors. Half are dairy free (vegan) and half use whey protein (the "gold standard" for muscle building). Two are coated in organic dark chocolate, two are soft chocolate chip cookie dough flavors and two are fruit and nut butter flavors. For all their differences, they all have a virtually identical balance of complete nutrition. A whole lot of choice in just a few bars!
