What's in the Berry Burst TREK bar?

Think trail snack first, protein bar second: dates and raisins form the base, gluten-free oats add chew, and freeze-dried raspberries bring that tart pop.

Protein comes via crisp soy pieces—light and crunchy instead of dense—while additives stay minimal, with a little tapioca starch to hold the crisps and rice starch plus natural flavorings to keep the berry notes consistent.

Macros lean toward quick energy: higher carbs and sugars, very low fat, and modest protein. The sweetness comes entirely from fruit, including apple, pear, and grape juice concentrates—flavors your tongue reads as fruit, but sugars your body absorbs quickly.

What are people saying?

Main praise: Reviewers love the clean, fruit-led flavor and crunchy soy texture—no artificial aftertaste, easy to grab-and-go, and reliably tasty on the move.

Main criticism: The macro math turns some shoppers off: roughly 10g of protein alongside about 25g of sugar feels more like an energy bar, with occasional notes about dryness and value.

Bottom Line

Best for pre-run or mid-hike fuel, or anyone who prefers plant-based, fruit-derived sweetness and a light, crunchy texture without sugar alcohols. Less ideal if you’re chasing 20g of protein or minimizing sugar.

What's in the Lemon Meringue Pie No Cow bar?

Vegan and dairy-free, this bar squeezes 22g of pea-and-brown-rice protein into 190 calories, with its lemon-meringue character built from natural flavors and a pinch of citric acid rather than actual lemon pieces.

Texture comes from almond bits and pea-protein crisps, so it doesn’t eat like a taffy slab.

It uses five modern helper ingredients—soluble corn fiber and glycerin for bulk and softness, plus a sweetener blend of erythritol (a zero-calorie sugar alcohol), stevia, and monk fruit—to keep sugar low without ditching sweetness.

Most of the 25g carbs are fiber or low-calorie sweeteners, so energy tends to land steadier than a syrupy bar, and fat stays modest at 4g.

What are people saying?

Main praise: It’s an efficiency play: 22g of dairy-free protein for 190 calories with steady-feeling energy and a lemony break from endless chocolate, earning best-in-class nods for vegan macros.

Main criticism: Taste and texture divide people—some find it dry or chalky with a stevia/erythritol aftertaste and occasional GI rumbling, with batch-to-batch consistency a question mark.

Bottom Line

Best for macro-first snackers and dairy-free eaters who want a big protein bump in a small-calorie package—and who do fine with sugar alcohols.

What's in the Cherries + Berries MacroBar GoMacro bar?

GoMacro’s Cherries + Berries MacroBar reads more like an oat-and-fruit square than a classic protein bar. Organic dried cherries and cranberries (sweetened with apple juice concentrate) and raisins are folded into gluten-free rolled oats, then bound with brown rice syrup and a touch of almond butter.

It’s fully plant-based and organic, with fats coming mostly from almonds and a little sunflower oil, and protein that’s naturally occurring rather than added from isolates. The fruit pieces are lightly oiled so they don’t clump, and a hint of natural flavor rounds out the cherry–berry profile.

Short list, recognizable ingredients, no sugar alcohols or artificial sweeteners—expect quick energy more than muscle-focused macros.

What are people saying?

Main praise: Fans love the clean, organic ingredient list, the tart cherry–cranberry flavor, and the substantial chew—especially with no whey or sugar alcohols to upset sensitive stomachs.

Main criticism: With just 4g of protein and 14g of sugar, some find it too sweet and too sticky for a “protein bar,” and a few report digestive discomfort from the concentrated sugars, especially given the price.

Bottom Line

Best as a pre-walk or mid‑afternoon pick‑me‑up for vegan and gluten‑free eaters who want simple ingredients and quick carbs without whey or sugar alcohols.

What's in the Blueberries & Cream Promix Nutrition bar?

Promix Nutrition’s Blueberries & Cream leans into an airy marshmallow-meets-cereal build anchored by whey protein puffs, with a small assist from egg whites. That combo delivers 15g of complete, fast-digesting protein while keeping calories to 150 and fat to 4g, thanks to a puffed structure and minimal oils.

Carbs land at 16g, largely from tapioca syrup and a bit of starch for quick lift, balanced by soluble fibers—tapioca fiber (a resistant dextrin) and inulin from Jerusalem artichoke—that take the edge off the spike.

The blueberry is not just flavoring: blueberries, currants, and blueberry extractives bring real fruit, and the sweetness comes without artificial sweeteners.

What are people saying?

Main praise: Reviewers love the rice-crispy crunch with real blueberry pops and clean sweetness—no sugar alcohol aftertaste—and outlets like SELF, EatingWell, and Health have called it out as a satisfying, easy-to-digest pre-workout snack.

Main criticism: Expect a drier, slightly crumbly crunch rather than gooey marshmallow, a whisper of coconut, and potential inulin-related stomach grumbles—plus it’s a snack, not a meal.

Bottom Line

Reach for it as a pre‑workout or light afternoon snack when you want something crisp, not heavy. Also a fit if you prefer gluten‑free bars with no peanuts in the ingredients and a moderate 5g of sugar.

What's in the S'mores Orgain bar?

Orgain’s S’mores Protein Bar stays plant-based, using an organic blend of brown rice protein, pea crisps, and a little chia, then leans on real chocolate chunks for the campfire flavor. At 150 calories with 5 grams of fat and 6 grams of sugar, it reads more snack than meal replacement.

Its 16-ingredient recipe relies on refined binders—tapioca syrup and a starch-derived IMO—plus erythritol (a sugar alcohol) to keep sweetness up while listed sugars stay modest, and it uses four functional add-ins to keep the texture soft and stable.

Fats come mostly from almonds and chia, with a touch of cocoa butter, so you’re looking at a mostly unsaturated fat profile. If you prefer oat- or date-based bars, note this formula is more engineered to control sugars and texture.

What are people saying?

Main praise: Taste is the headline: it eats like a treat without being cloying, and at 150 calories with 10 grams of plant protein, it nails the snack brief.

Main criticism: Lighter protein and fiber, plus the erythritol/IMO sweetness and slightly gritty chew, won’t suit every stomach or every appetite.

Bottom Line

Reach for it when you want a sweet, plant-based pick‑me‑up or a pre‑walk nibble without dairy or soy. Skip it if you need 20 grams of protein or prefer bars built from oats, dates, and nuts only.

What's in the Chocolate Brownie PROBAR bar?

Chocolate Brownie doesn’t fake the chocolate—there’s real cocoa, unsweetened chocolate, and a touch of alkalized cocoa for a deeper, brownie-like profile. The protein backbone is soy protein isolate, which keeps the bar fully vegan.

Energy leans carb-forward: tapioca syrup and cane sugar provide the lift, and a refined cassava fiber helps smooth the sweetness. Fat stays low at 5 grams, so the bar eats light and works well as pre-activity fuel.

To hold that soft, cohesive texture, it relies on a few helpers (about three additives): glycerin to lock in moisture, that soluble fiber as a binder, and lecithin to keep things mixed.

What are people saying?

Main praise: Reviewers love the candy-bar-level chocolate and smooth consistency, calling it one of the best-tasting vegan bars with 20 grams of complete protein—and it often sits well thanks to the lack of sugar alcohols.

Main criticism: The sweetness is heavy for some, texture can come off chalky or dry, and the soy base rules it out if you avoid soy.

Bottom Line

Best for pre‑workout or long days when quick energy plus protein makes sense, and for chocolate lovers who prefer real sugar over sugar alcohols. Not ideal if you’re avoiding soy or seeking a low‑sugar, slow‑burn snack.

What's in the Lemon Coconut SimplyProtein bar?

Bright lemon meets toasty coconut in a plant-based bar built on soy protein crisps. Those crisps—soy protein isolate lightly bound with tapioca—deliver complete vegan protein while keeping the texture light and snappy.

Energy comes from oats and brown‑rice crisps, steadied by chicory root fiber, with fats kept modest via cashew butter, sunflower oil, and a sprinkle of coconut. Sweetness leans on a small amount of cane sugar, rounded out by vegetable glycerin (a plant‑derived syrup that keeps bars moist) and natural flavors.

The result is a gluten‑free, dairy‑free bar with mid‑pack protein and very low sugar—more crisp snack than candy‑bar clone.

What are people saying?

Main praise: Fans love the crisp, airy texture and the restraint—13g of vegan protein, very low sugar, and no stevia or sucralose—with a bright lemon‑coconut flavor that plays well with coffee.

Main criticism: Detractors call it dry or powdery and find the lemon coconut flavor polarizing, and a few sensitive stomachs don’t love the chicory root fiber and glycerin.

Bottom Line

Choose it if you want a light, crunchy, plant-based snack between meals or a gentle post‑workout bite with a citrus twist—and you prefer low sugar without high‑intensity sweeteners. Skip it if you avoid soy or tree nuts, or if you want a dense, brownie-like protein bar.

What's in the Milk & Cookies Oatein bar?

Milk & Cookies, reimagined for the gym bag: Oatein builds this bar on milk protein isolate and whey protein isolate, then adds a milk‑chocolate coating and a soft caramel layer for a true dessert bite.

The cookie notes come from oat flour and crunchy soy crisps.

Macros land in a friendly place—about 18g of protein, modest fat, mid‑pack carbs, and only a small amount of sugar—because most of the sweetness comes from maltitol (a sugar alcohol made from starch) and refined soluble fibers that add bulk without as many calories.

These sweeteners are typically gentler on blood sugar than table sugar, though they’re not zero‑impact. It’s a deliberately engineered recipe, more processed than nut‑and‑date bars, in service of that candy‑bar chew.

What are people saying?

Main praise: Taste and texture win: a fudgy, milk‑chocolate‑and‑caramel bar that many reviewers say they’d happily reorder.

Main criticism: The low‑sugar magic relies on maltitol and other functional ingredients, which can bother sensitive stomachs and, paired with dairy/soy/wheat, rule it out for keto, gluten‑free, or vegan eaters.

Bottom Line

pick‑me‑up for people who want solid protein without a heavy, nutty bar—and who tolerate sugar alcohols and aren’t avoiding gluten, soy, or dairy.

What's in the Blueberry RXBAR bar?

RXBAR Blueberry keeps it simple: dates, egg whites, almonds, cashews, blueberries, and a touch of natural flavor. The protein base is egg whites—a complete source—with most of the energy coming from fruit carbs.

Compared with many protein bars, it runs higher in carbs and sugar and lower in calories and fat, so it eats light yet sweet. Additives are minimal—no sugar alcohols, emulsifiers, or thickeners—just natural flavors to keep the blueberry note consistent.

Main criticism: The texture divides the room: a dense, sticky chew that can cling to teeth, paired with a modest 12g of protein.

Bottom Line

Pre‑workout or mid‑morning snacking when you want fruit‑forward energy with 12g of complete protein and you don’t mind a chewy, date‑and‑nut texture.

What's in the Cookie Dough Misfits bar?

Built on a trio of plant proteins (soy, pea, and fava), Misfits Cookie Dough chases cookie‑dough nostalgia with cocoa, unsweetened chocolate, and cocoa butter for that creamy melt. Rice flour and a touch of tapioca shape the doughy bite, while glycerin keeps it soft.

The macros are modern: 15g protein, 190 calories, and very low sugar, with most carbs coming from refined fibers and a sugar alcohol designed to tame spikes versus regular sugar. Fat stays modest at 6.

4g from cocoa butter and sunflower oil. Expect a contemporary low‑sugar build—18 ingredients, 5 functional additives—crafted to deliver a candy‑bar feel without the sugar rush.

What are people saying?

Main praise: Reviewers love the fudgy, chewy, candy‑bar taste that actually hides the chalkiness common in plant‑protein bars.

Main criticism: Texture and sweetness divide the crowd—some find it gummy with a stevia‑forward aftertaste, and the maltitol/fiber blend can be rough on sensitive stomachs.

Bottom Line

Great for dairy‑free snackers who want a dessert‑leaning protein hit after lunch or post‑workout without a sugar rush. Best if you enjoy soft, fudgy textures and tolerate sugar alcohols.
