Out of all the Luna bars the lemon zest is by far my favorite since I tried it years ago it is just such a great flavor that you don’t find where the other nutrition bars it’s great for in the mornings but it’s also great for an afternoon pick me up and they store while and you can throw one in your purse and just go and it will be great later on in rush I cannot recommend this Luna bar enough and I have told all my friends about him I buy them by the box and bulk

These are great! I love nutrition bars for snacks and during college I basically lived off of various bars. So I really had to find something that had some substance to it. Luna bars were good for this. They are thick and filling and the Lemon flavor made it a little more refreshing. They can be a bit chalky at times which is not uncommon for nutrition bars.

This is the best bar. The macros are not the best, but it always is not about that. I love the flavor on these. They keep me full for a long time. They have such a good texture. Not crunchy, but not like taffy like RX bars.

These are surprisingly good. I love lemon flavor everything and these are a decent flavor of lemon. They're sort of dry but not chalk and cardboard dry. They work great as a mid morning snack or even a between meal pick me up.

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.

Oh my gosh I love Luna bars! The lemon is one of my favorites. Great refreshing taste, tangy drizzle on top, feels like a dessert but is actually really good for you?! Score!!

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.
