Answer: almost all of them are vegan!
Clif Bars are a god send to any vegan who plays hard or travels a lot. These bars pack a ton of calories and protein, and taste excellent too. Just what you’d expect from something that started in someone’s garage. Into it.
As far as which ones are vegan, Clif Bar has a handy-dandy display on their website. There’s a checkbox for “vegan.” Easy as that. From what I can see, the only two original style bars that are NOT vegan are the mini blueberry crisp and the mini chocolate chip peanut butter (not sure why the mini ones are not vegan, the regular sized ones are …). Check it out for yourself, it’s fun.
And for those concerned about the use of “palm oil,” check this response from a ClifBar rep. Thumbs up.
