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 Pumpkin Pie No Cow bar?

No Cow’s Pumpkin Pie leans modern: big plant protein, low sugar, and a texture engineered to stay soft, with four functional add-ins keeping things sweet and pliable.

The 22g of protein come from a pea-and-brown-rice blend, while most of the 25g of carbs are built from soluble corn fiber (a refined fiber from corn starch that adds bulk and can help avoid sharp sugar swings for most people), glycerin (a plant-derived moisture keeper with a gentler glycemic effect), and the starch in pea-protein crisps instead of cane sugar.

Fat stays modest and mostly from almonds, with small amounts of palm oil and cocoa butter to hold the bar together. Sweetness comes from erythritol plus stevia and monk fruit, keeping sugar to 1g.

The pumpkin-pie moment is mostly warm spices via natural flavors rather than actual pumpkin purée.

What are people saying?

Main praise: Reviewers love the macro math—a rare 22g of vegan protein under 200 calories with a softer chew—and outlets like BarBend and SELF routinely call it a practical, filling pick.

Main criticism: The flashpoint is taste and texture: some flavors read dry or chalky with a stevia/sugar-alcohol aftertaste, batches can vary, and the fiber/sugar-alcohol blend bothers a few stomachs.

Bottom Line

Macro‑first snackers and dairy‑free athletes who want a lean, high‑protein bar and don’t mind (or even like) stevia/erythritol sweetness. Great after training or as a fiber‑rich tide‑you‑over between meals.

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 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.

What's in the Birthday good! snacks bar?

Meet good! snacks’ Birthday Protein Bar: a vegan, gluten‑free slice of cake nostalgia built on a plant protein duo of fava bean and brown rice.

The macros read like quick fuel—15g of protein with carb‑leaning energy from tapioca syrup and cane sugar, cushioned a bit by soluble tapioca fiber. Fat stays modest at 6g from almond and peanut butters and high‑oleic sunflower oil, with a little palm kernel oil to hold everything together.

No vitamin fortification here; the party comes from sprinkles bound with gum arabic and colored with plants like spirulina, red cabbage, turmeric, and radish, plus natural flavors.

Bottom Line

Reach for it when you want a sweet, dairy‑free protein boost with quick energy—before a workout, between meetings, or as a treat‑ish snack that isn’t artificially sweetened.

What's in the Peanut Butter & Jelly Skout Organic bar?

Skout Organic’s Peanut Butter & Jelly Protein Bar sticks to the classics: organic dates bind the bar, peanut flour and peanut butter supply the plant protein, and real strawberries bring the jammy nostalgia, lifted by a hint of strawberry essence.

This is more fruit-and-nut energy than protein juggernaut, with 10g of peanut-based protein. Carbs and sweetness come from whole fruit rather than syrups or sugar alcohols, and fat stays modest and mostly unsaturated thanks to peanuts.

At 200 calories, it reads like a lunchbox throwback—just with better ingredients.

What are people saying?

Main praise: Fans love the super-short, organic ingredient list, the real-fruit PB&J flavor, and a chewy texture that satisfies without sugar alcohol side effects.

Main criticism: Texture can feel dense (especially cold), protein is modest for a “protein bar,” and the fruit sugar—and price—read high to some shoppers.

Bottom Line

Best for plant-based eaters, kids, and anyone who wants real-food PB&J flavor and steady energy in a tidy 200-calorie bar; less ideal if you need 20g protein or keep carbs very low.
