I finally tried these ThinkThin bars after scoffing at them whenever I saw them in the supermarkets. (Plus, they went on sale.)
With a gimmicky name that uses the word "thin," I was skeptical. Also, since the bar wasn't vegan, I was doubly dubious.
On the upside, this bar contains 20 grams of protein and no sugar, so it's actually not a bad meal-on-the-go (part of that meal, anyway, if your appetite is like mine).
The downside is that I didn't like the taste of this bar. Eating it reminded me why I stopped eating whey protein (which contains little lactose and is generally OK for my intolerant self). It is not nearly as delicious as Clif Builder bars, so I think it's unlikely that I will bother with them again.
Bottom line, if you are not vegan and don't mind the whey taste, I'd say it's not a bad energy bar.
