These are another one of my running essentials! They’re some of my favorite post workout/post race snacks. It’s the perfect size for me because it’s not like an entire meal like some other bars but I’m still getting all the protein I need. Plus, it tasted like it could be a candy bar.

Luna bars are one of my favorite solutions to protein in a rush. These bars are easy to find at most grocery stores so you don’t have to make a special trip to get them. The low glycemic index means that i don’t ride the roller coaster of a sugar high. Plus the flavor is great!

Review for: LUNA® Protein Chocolate Peanut Butter Bars 7 ct Box more...
This product tastes great! It’s full of protein and has a nice taste which is good. The only downside is that there are only 7 bars in the box and it is pricey. However, it is a competitive price to other protein bars that are also expensive.

I buy these for my son that isn’t much of a eater. It gets him the protein he needs and helps him gain weight. They are a great product. We have bought most of the flavors they make. I would recommend and you can buy at Walmart.

I love these peanut butter chocolate Luna Bars! They are fairly healthy. I am not supposed to have much sugar, which they do have sugar in them but they are worth it! I purchase from Walmart, about $5-6 a box for a pack of six.

Sometimes it hard for me to get protein in my system, but these bars make it easy! They are loaded with protein and put two of my favorite things together, chocolate and peanut butter. If anyone is looking for a meal bar, I would recommend these !

I didn’t really like this bar. I usually am a huge fan of Luna bars and I usually think they taste super duper good but for some reason I thought this bar was weird and kinda chalky wich was strange to me

These bars taste fair and definitely keep me filled. The chocolate is good but the peanut butter tastes a little off. They aren’t my favorite protein bars, but I still buy them every once in a while.

Not my favorite protein bar but its not my least favorite either. Really can’t go wrong with chocolate and peanut butter. Not the cheapest option either so it’s not the one I normally reach for.

I find these a good post-workout snack or if I’m running late to class I can grab this bar and eat it in the way. I don’t feel the urge to eat until my next meal. I love all the flavors and have yet to experience a bad one
