I’m pretty sure I only survived college because of these. LUNA bars have the perfect blend of textures—you get creamy, crunchy, and gooey all in one bite. The lemon zest cuts through the sweetness of the rest of the bar, so the flavor doesn’t become too dense (which is the problem I face with pretty much any other protein bar.) They are a little pricey, but they really do function as a meal replacement and are perfect for when you’re on the go.

Luna Lemonzest Nutrition Bar I’m fully convinced I used to live off of these snack bars in high school.. needless to say, they are nutritional and hunger satisfying! The lemon is my favorite flavor but I do like to indulge in the peppermint around the holidays! I’ve gone vegan since I last had a Luna bar so I’m interested in finding out if they still have options available for my new dietary restrictions.

Hiii I have revisited these bars (am also no longer vegan) and I remember why I love them so much. They literally encompass the yummy lemon-zesty flavor that I constantly crave. They are coated with a lemon “creme” on the bottom and it’s so delicious.

I am completely hooked on these! Definitely one of my favorite snacks whether I’m at home or on the go. After discovering these I have tried multiple flavors of Luna bars - while any have yet to disappoint, these ones are still my go-to. I also love the quotes/sayings on each wrapper as well as the fact that they are gluten-free and non-gmo. Not to mention they are super yummy!

This is my favorite quick snack to stave off hunger when I'm busy. I always have one in my purse. They really do fill you up until you have time to eat a real meal, lowering your chances of binging on junk out of desperation. They also give you a boost of protein and vitamins.

These bars are so good! They're my all-time favorite healthy bars ever. I stumbled upon them at my college campus about 3 years ago and they've become my first choice when I'm feeling like I wanna splurge on my groceries. I'm a college student so I am on a budget and these are too expensive to buy a whole box of (the only downside is the super high price). They taste so good I almost feel like I am having a junk food bar haha these are so great! This flavor is my favorite too- I've never even bought a different flavor because this one is so tasty.

I love these! They have a great lemon flavor and all the nutrition that comes along with a Luna bar. I pack these for any trips I will be on where I don’t know where I will be eating meals. Perfect snack to hold me over until I am able to find something more nutritious.

I seriously eat these luna lemon bars every single day. They are so delicious and perfect for when you’re on the go! I keep these in my work and gym bag. I always have to have these for road trips and pretty much anytime I leave my house. You could say I’m addicted 😋

This is my favorite Kuna bar flavor. It keeps me full for a while. It is very delicious. The ogre diners all seem to be natural and it is not highly processed. Not too much sugar is added and it has a good amount of protein.

Usually my go to granola bar strictly for the fact that they’re so damn good. It doesn’t really taste like I’m eating a healthy snack but I am. I never thought in a million years that the lemon would be good but it’s honestly my favorite one and I’m a chocoholic.
