When to choose think! Peanut Butter Chocolate Chunk
Post‑workout or hold‑you‑over snacks when you want very low sugar and real satiety, and you’re comfortable with milk‑based protein and sugar alcohols.
What's in the think! bar?
think!
Peanut Butter Chocolate Chunk comes in with a dairy-powered core—milk protein isolate plus whey protein isolate—packing 20 grams of complete protein into a bar that tastes like peanut butter studded with chocolate.
The flavor is built from real peanut butter and peanuts, unsweetened chocolate, cocoa butter, and cocoa powder, while the very low sugar is achieved with fiber and non‑sugar sweeteners rather than fruit.
Macros land in interesting places: protein is top‑tier, carbs are mid‑range but largely from polydextrose fiber, glycerin, and sugar alcohols, and fats sit slightly above average thanks to nuts and cocoa butter.
If you’re after steady energy without a sugar surge—and you’re fine with refined sweeteners—this bar fits the brief.

Protein
2015HIGHMost of the 20 grams of protein come from a dairy duo: milk protein isolate (a casein‑plus‑whey blend) and fast‑digesting whey protein isolate. That means complete amino acids with relatively low lactose and a mix of slow and quick digestion—useful for satiety and recovery—though it is a refined, milk‑based protein if you avoid dairy.
Fat
119MIDThe 11 grams of fat are driven by peanuts/peanut butter and almond butter (mostly monounsaturated fats), plus cocoa butter and a bit of peanut oil. You get a mix of heart‑friendly unsaturated fats with some saturated fat—largely stearic acid from cocoa butter—and an overall fat level that’s slightly above average among bars. If you’re watching omega‑6, note the inclusion of refined peanut oil, though the total here is modest.
Carbs
2020MIDThese 20 grams of carbs skew toward formulation carbs rather than sugar: polydextrose (a low‑calorie soluble fiber) and vegetable glycerin supply bulk and softness, while erythritol and a touch of maltitol syrup add sweetness. The result should be gentler on blood sugar than a sugar‑based bar, though sugar alcohols can bother sensitive stomachs, especially if eaten quickly or alongside other polyols.
Sugar
14LOWSugar is kept to 1 gram because sweetness is supplied by sugar alcohols (mostly erythritol, with a small amount of maltitol), a little glycerin, and high‑intensity sweeteners (sucralose and stevia). That keeps sugars low without fruit, but it does rely on highly refined sweeteners; if you’re sensitive to polyols, consider how this fits with the rest of your day.
Calories
220210MIDAt 220 calories, this bar lands just above the category average—unsurprising given the 20 grams of protein and 11 grams of fat. A meaningful slice of the listed carbs comes from low‑calorie fiber and erythritol, so more of the calories actually come from protein and the nut/cocoa fats, which can help with fullness.
Vitamins & Minerals
No standout micronutrients here—nothing tops 10% of Daily Value. You’ll pick up small amounts of calcium from the milk proteins and a bit of iron and magnesium from cocoa and nuts, but not enough to make this a vitamin/mineral play.
Additives
To deliver a soft, low‑sugar bar, this recipe leans on modern helpers: polydextrose (a synthetic soluble fiber) and vegetable glycerin for moisture and body; sugar alcohols for bulked sweetness; sunflower lecithin to help fats and water play nicely; and sucralose plus stevia to sharpen sweetness. They work as intended, but it’s not a minimal‑ingredient approach—more “engineered low‑sugar” than whole‑food sweet.

What are people saying?

Range
“I am eating think protein bars. Decent amount of protein (20g). Dont repulse me like so many out there”
“the Think high protein brownie crunch bar is honestly good if you want a different flavor, I found the one on the top to be pretty decent but defo think the brownie one is better”
“Chocolate brownie one was AMAZING!”
Main Praise
The big win here is taste and satisfaction.
Across Reddit and editorial reviews, flavors like Brownie Crunch and Lemon Delight get called out as legitimately good—more candy‑bar nostalgia than “gym chalk,” with a dense, chewy texture that feels like a real snack.
SELF’s editors even named the line a runner‑up overall for flavor and fullness, and BarBend echoed that “candy‑like” appeal while still delivering 20 grams of protein. Amazon reviewers frequently note that a bar keeps them full for hours; one even uses half before a long bike ride and feels energized the whole way.
For people who’ve cycled through a dozen bars and found most of them repulsive, several Redditors said think! is one they can actually enjoy.
In short: high protein, low sugar, and a taste that converts skeptics.
Main Criticism
The tradeoff is the sweetening strategy. These bars rely on sugar alcohols (mainly erythritol, with a bit of maltitol) and high‑intensity sweeteners, and some people report bloating, gas, or a sharp aftertaste.
A few reviewers describe the occasional off‑note—“sour” or overly sweet—especially if you’re sensitive to sucralose or stevia. If you want a minimalist ingredient list or sweetness from dates or fruit, this isn’t that lane.
Calorie‑chasers also point out that at roughly 220 calories, it’s not a “diet mini bar,” though that’s partly why it’s more filling. Finally, ingredient nuances vary by flavor and product line, and a handful of users with soy allergies have flagged issues—so labels matter.
The Middle Ground
So which story wins: the “actually tasty and filling” bar, or the “my stomach said no” bar? Both, depending on your physiology and expectations.
On the plus side, the protein is a smart mix of milk protein isolate and whey isolate—complete amino acids, relatively low lactose, and a slow‑plus‑fast digestion profile that’s great for satiety and recovery.
That, paired with nut and cocoa fats, explains why many folks like Amazon’s Small Town Girl report hours of fullness. But sugar alcohol tolerance is personal: Men’s Health notes around 13 grams in certain flavors, which some stomachs dislike.
Redditor Unavailable called the chocolate brownie flavor “AMAZING,” while another simply said, “did not like it LOL”—two ends of the same spectrum. If you’re polyol‑sensitive, start with half a bar and some water, and don’t stack it with other sugar‑alcohol foods in the same meal.
If you’re not sensitive, you’ll likely get candy‑adjacent flavor, 20 grams of protein, and steady energy without a sugar crash.
What's the bottom line?
think! High Protein Bars, especially Peanut Butter Chocolate Chunk, deliver what many bars promise and few nail: 20 grams of complete protein, a genuinely satisfying chew, and dessert‑leaning flavor with just 1 gram of sugar. It’s more engineered than minimalist—fiber, sugar alcohols, and modern sweeteners do the heavy lifting—so the fit depends on your preference and your gut.
If you tolerate sugar alcohols, this is an easy, reliable grab for post‑workout or a late‑afternoon hold‑over. If you want fruit‑sweetened, short‑list ingredients or you’re highly sensitive to polyols, look elsewhere. Practical take: check your flavor (they’re not identical), sip water, and see how half a bar sits before making it your daily driver.
For many, the payoff—a bar that actually tastes good and keeps you full—is absolutely worth it. Condensed listicle version: Dessert‑leaning, low‑sugar bar with 20 grams of complete dairy protein and a dense, satisfying chew. Great post‑workout or as a steady energy snack if you tolerate sugar alcohols; less ideal for minimal‑ingredient purists or polyol‑sensitive stomachs.
