What's in the Peanut Butter Chocolate SimplyProtein bar?

SimplyProtein’s Peanut Butter Chocolate builds flavor from real peanuts and unsweetened chocolate, then holds it together with soy protein crisps—soy protein isolate puffed into crunchy bits.

The label stays tight: seven core ingredients by our count, plus three functional add-ins that lean on chicory-root inulin and acacia (plant fibers) and a touch of plant-derived glycerin (a syrup that keeps the bar soft) to keep sweetness gentle without artificial sweeteners.

Fats come mostly from peanuts, with small amounts of peanut and sunflower oils; carbs come from brown rice crisps and a little cane sugar, with those fibers adding body and mild sweetness.

It’s vegan and gluten-free, and it eats like a light, crisp snack rather than a dense meal replacement.

What are people saying?

Main praise: People love the deliberate cereal-like crunch and crowd-pleasing peanut-butter–chocolate flavor, plus 13 grams of plant protein with very little sugar—and no stevia or sucralose.

Main criticism: For some, the crisp reads as dry or chalky with a faint aftertaste, and 13 grams of protein won’t satisfy anyone chasing a 20-plus-gram bar.

Bottom Line

Choose this if you want a lighter, dairy‑free protein snack with an actual crunch and restrained sweetness. Great between meals, with coffee, or after a light workout when you want something tidy and not cloying.

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 White Chocolate Cinnamon Almond KIND bar?

Think roasted almonds and peanuts dressed in warm cinnamon with a white‑chocolate–style drizzle. KIND builds the protein on soy protein isolate—a complete plant protein—supported by those nuts and a touch of milk powder to land at 12g.

It’s a rich, staying-power snack thanks to fats from the nuts, cocoa butter, and palm kernel oil. Sweetness comes from pantry staples—sugar, honey, and glucose syrup (a starch‑derived syrup that binds and sweetens)—balanced by chicory root fiber to help slow the rise.

The ingredient list is short with minimal additives (just one by our count), and soy lecithin keeps the coating smooth.

What are people saying?

Main praise: Taste and texture lead the applause: a real roasted‑nut crunch with cinnamon‑white‑chocolate vibes, no chalk, no sugar alcohols—just 12g of protein and meaningful fiber in a bar people actually want to eat.

Main criticism: Skeptics call 12g more “snack” than “protein bar,” some report chicory root fiber discomfort, the drizzle bumps saturated fat, and honey plus milk powder mean it isn’t vegan.

Bottom Line

A satisfying afternoon pick‑me‑up for people who want a crunchy, dessert‑leaning bar without sugar alcohols and don’t need a 20‑gram protein bomb. Great for gluten‑free, vegetarian eaters who like warm spice and real‑nut texture.

What's in the Mint Chocolate PROBAR bar?

PROBAR’s Mint Chocolate Protein Bar is plant‑powered and unapologetically dessert‑leaning: 20g of soy protein isolate wrapped in cocoa and a cool mint finish.

It runs higher in carbs for a protein bar, mostly from tapioca syrup (a quick‑absorbing cassava‑based sweetener), table sugar, and tapioca starch, with soluble tapioca fiber added to bring some fiber and that soft‑chewy texture.

Fats sit in the middle—palm kernel oil gives the chocolate its snap while safflower oil brings unsaturated fats—and the whole thing lands at 270 calories, closer to a small meal than a wispy snack.

The ingredient list stays concise (16 total) with three functional add‑ins—vegetable glycerin, soluble tapioca fiber, and lecithins—there for moisture, binding, and smoothness.

What are people saying?

Main praise: Fans say it tastes like a mint‑chocolate dessert without sugar‑alcohol aftertastes—and the 20g of complete soy protein actually keeps you full.

Main criticism: Critics flag the 270 calories and 12g of sugar, a sometimes‑dry texture, and the soy base as deal‑breakers for some.

Bottom Line

Pick it for post‑workout refuel, long hikes, or anytime you want a plant‑based protein hit that doubles as a chocolate‑mint treat. Skip it if you’re avoiding soy or chasing ultra‑low‑calorie snacks.

What's in the Chocolate Mint CLIF bar?

Chocolate mint fans, meet a plant-powered heavy hitter: CLIF’s Chocolate Mint Protein Bar uses soy protein isolate and concentrate to hit 20g of complete protein. For sweetness and structure it leans on cane sugar and brown rice syrup—fast-burning carbs—plus a palm-kernel-oil chocolate coating that stays crisp in a backpack.

It’s vegan and gluten-free, with its mint-chocolate flavor coming from cocoa, unsweetened chocolate, and a touch of natural mint. You also pick up meaningful iron and phosphorus from the soy and cocoa, and a couple of standard bar additives keep the texture stable and the coating smooth.

The tradeoff is higher sugar and carbs than many bars, so think fast fuel plus protein rather than a slow, all-afternoon nibble.

What are people saying?

Main praise: Taste leads the applause: a mint-chocolate shell with a substantial chew that people actually enjoy, backed by a real 20g of dairy-free protein.

Main criticism: The drawbacks are clear—280 calories and 17g added sugar, a palm-oil coating higher in saturated fat, and a texture some find dense, especially when cold.

Bottom Line

Best for pre‑ or post‑workout fuel, or a purposeful between‑meal bridge when you want a tasty, dairy‑free 20g protein hit. Less ideal if you’re minimizing added sugar or avoiding soy.
