Everything You Need to Know About the Protein Bar That's All Over Instagram

Reaching for greasy, carb-loaded, and sugary snacks is almost too easy when you're on the go. We've all been there. But since these foods can leave you feeling groggy and bloated, health-conscious gals have made it their goal to hunt down clean and tasty bites.

While this may seem like a difficult feat, the search is actually quite simple. The answer has been in your Instagram feed all along. RXBARs are the highly photogenic protein bars that fitness influencers (and probably even your closest friends) can't get enough of. We're sharing every important thing you need to know about these clean snacks that seem to be everywhere.

When "mindful" is your life motto, whole ingredients are basically your clean-eating BFF. Part of what makes these aesthetically pleasing bars so intriguing are their labels. Each reveals the core ingredients — 3 Egg Whites. Nuts. 2 Dates. No B.S. — that help eliminate midday stomach growls and hangry outbursts while filling the bar with 100 percent whole goodness. To stay true to the brand's whole-ingredient promise, the additions that flavor each bar are also totally clean, like 100 percent cacao and sea salt in their popular Chocolate Sea Salt flavor.

What's a protein bar without the protein? While countless bars sneak in a surprising amount of suspicious ingredients, these go the wholesome route by using egg whites for a nutritional boost. Unlike all those false or mysterious claims on most bars, this protein source is fresh, natural, and cholesterol-free.

RXBARs come in so many tasty flavors that even the pickiest of eaters will find one they like. Even better, the brand is constantly releasing new and seasonal options, so there's always a new way to treat your taste buds. Among our must trys? Chocolate Sea Salt for that perfect balance of sweet and savory, Blueberry when you're in the mood for fresh flavors, and Peanut Butter Chocolate for a delicious snack. Shop a sample pack of the top RXBAR flavors here ($27 for a pack of 12). Bonus: if you're already dying to try them, enter discount code POPSUGAR at checkout for 25 percent off.

Gluten- and dairy-free eaters, rejoice! Finding a tasty snack that fits into a strict diet can be difficult — and leave you excluded from enjoying countless snacks — but these bars are all about inclusivity. Need more proof? They're also free of unnatural added sugar and soy.

In this case, "No B.S." means exactly that. These bars are seriously tasty, seriously clean, and seriously good for you. They're filling enough to help you power through the afternoon slump, sweet enough to curb your dessert obsession, and versatile enough to enjoy for breakfast or a post-workout snack. Regardless of which flavor you try, you'll never have to worry about snacking on artificial flavors, preservatives, or ingredients you can't pronounce again.
