Many Luna Bars are vegan. An offshoot of Clif Bar, Luna is a vegan friendly energy bar. They have fewer calories than their “bigger brother,” the Clif Bar. The Luna Bar website does a nice job of identifying their ingredients and sources. Both Nutz Over Chocolate and Caramel Brownie appear vegan based on the ingredient list. FYI: The Peanut Honey Pretzel bars contain honey.
