These are my go-to protein bars. Most protein bars make my throat hurt for whatever reason, but these do not do that at all. They satisfy my sweet tooth without making me feel too guilty about indulging. The only negative about them is that the lemon on the bottom of the granola will melt, so you can't leave them in your gym bag in the car while you are at work or whatever. They can get messy if you do that.

I love Luna bars! Especially this flavor. It doesn't taste artificial, like other brands often do.

I love lemon. The combination of icing on the bottom and oats in top really leaves me feeling full.

Here’s the deal, I’m enough of an adult to know that this granola bar is closer to a candy bar than actual fruit but I still dig it. It tastes great and gives me a bit of extra energy when I need a quick boost.

My favorite granola bar. I love the taste, and they do just enough to keep me not hungry and focused on the task at hand. The one downside is that they're kind of pricey (around $1 a bar), but sometimes I find they're worth it. LOVE!

One of my favorite lemon bars! I'm not a fan of chocolate flavored bars, and this is the perfect alternative! Sweet but slightly sour, and good all around! I do recommend this to others, especially people who don't like chocolate!

The Lemon Zest is my favorite flavor of the Luna Bars. I love how light, yet satisfying the flavor is and it keeps me full for an extended amount of time. I often times grab one of these in the morning as my substitute breakfast if I'm in a big rush.

This is my favorite flavor of Luna bar and I definitely think the flavor/texture has improved from when I first started eating them maybe a decade ago. It's like a rice crispy treat minus the gelatin and plus lemon and nutrients! I could eat a million of these.
