FITCRUNCH
Peanut Butter
TL:DR
In 2 Sentences
A chef‑designed, six‑layer, candy‑bar‑style protein bar that still delivers a massive 30g of whey‑based protein per full‑size bar—rare at this taste level.
When to choose FITCRUNCH Peanut Butter
Choose it when you need a quick, satisfying mini‑meal—post‑lift, between meetings, or on the road—and want dessert‑level flavor without mixing a shake.
What's in the FITCRUNCH bar?
FITCRUNCH’s Peanut Butter bar comes out swinging with 30g of whey‑forward protein—top‑tier for a bar—and a calorie count that nudges it into mini‑meal territory.
The protein backbone blends whey isolate/concentrate with soy protein isolate (plus a little sodium caseinate and gelatin for texture), while the peanut‑butter vibe is built from real peanuts, a touch of cocoa and vanilla, and a pinch of salt.
Carbs skew more processed—think sugar alcohols and syrups—while fats are a mix of nut oils and palm‑based structure, so expect big fullness and a rich, candy‑bar‑like bite alongside that muscle‑friendly protein.

Protein
3015HIGHMost of the 30g of protein comes from whey protein isolate and concentrate, with soy protein isolate and a bit of sodium caseinate rounding out the blend. That combo delivers a complete, highly digestible amino acid profile and a creamy texture; the small amount of gelatin helps bind but isn’t a complete protein. It’s an effective, if refined, mix—great for muscle repair, but not for those avoiding dairy or soy.
Fat
169HIGHFats here are a blend: peanuts and a little sunflower oil supply mostly unsaturated fats, while palm and palm‑kernel oils provide the firm, confection‑style structure. The palm‑based fats raise the saturated share compared with nut‑only bars, though you’ll also get a bit of natural vitamin E from the nuts and sunflower oil. If you watch saturated fat, this is one to note.
Carbs
2720HIGHThese are more ‘factory’ than ‘farm’ carbs. Sugar alcohols (like maltitol and sorbitol) and glycerin drive much of the sweetness and chew, with quick‑hitting sugars and refined starches (corn syrup/dextrose, maltodextrin, tapioca) filling in; a small amount of brown rice flour adds whole‑grain starch. Expect a mix of rapid and steadier energy rather than a slow, whole‑food burn—polyols can bother sensitive stomachs at higher intakes.
Sugar
64MIDOnly 6g of sugar appear on the label because most sweetness comes from sugar alcohols and glycerin, plus a tiny dose of an artificial sweetener (sucralose). That approach generally softens blood‑sugar spikes compared with straight table sugar, but maltitol still contributes carbohydrate calories and can upset sensitive guts in larger portions. A little dextrose/corn syrup adds some quick sweetness up front.
Calories
380210HIGHAt 380 calories, this eats like a light meal. Calories come from all three macros—roughly 120 from protein, 140‑plus from fats, and the balance from carbohydrates and sweeteners—so it’s built for staying power rather than a tiny tide‑me‑over. Great when you need heft; a lot for a casual snack.
Vitamins & Minerals
No standout fortification—nothing clearly tops 10% DV. Iron lands around 10% (likely from soy protein, cocoa, and nuts), with a modest calcium bump from the dairy proteins. Mixed tocopherols are added mainly to protect fats, and peanuts/sunflower oil add a small touch of vitamin E naturally.
Additives
To nail that soft‑yet‑structured bite, the bar leans on humectants, sugar alcohols, multiple emulsifiers, a preservative, anti‑caking agents, colors, and natural flavors. They keep it moist, uniform, and shelf‑stable—but they’re highly refined. If you prefer short, kitchen‑style labels, this one reads longer and more technical.

Range
“Just gotta toss a shout out for the Robert Irvine Fit Crunch bars. I just had a PB&J one for breakfast. Each bar has 30g of Protein. They taste really really good.”
“The Fit Crunch bars are great if you want something that tastes like a candy bar, but almost has the macros of a legit protein bar 190cals, 16g protein, 8g fat, 14g carbs”
“The Robert Irvine’s fit crunch bars. Just found these at Costco, they don’t spike me, and almost reminds me of Reese’s.”
Main Praise
Taste is the headline.
Across Reddit and Amazon, people keep calling FITCRUNCH the protein bar that actually tastes good—often “like a candy bar,” with a few Peanut Butter fans saying it reminds them of a certain famous cup.
That matters: enjoyment makes consistency easier, and a bar you look forward to tends to win out over chalky options.
The 30g of protein in the full‑size Peanut Butter version is another big draw, offering a complete amino profile from whey with backup from soy and casein, which is great for muscle repair.
Many reviewers also find it genuinely filling—more like a mini meal than a snack—so it can bridge a long morning or cover a post‑workout window without immediate hunger. Texture earns applause too: crisp coating, soft center, and peanutty bits that keep each bite interesting.
Main Criticism
Calorie density is the recurring complaint. At around 380 calories for the full‑size bar, several folks (like Redditor Various‑Traffic‑1786) call it “delicious but really high in calories,” which can undermine a casual snack strategy.
The sweetness system relies heavily on sugar alcohols (especially maltitol) and glycerin—fine for some, but a gut deal‑breaker for others. Multiple commenters mention GI distress, and one even framed it as “abusing the sugar alcohol loophole.
” The ingredient list is long and includes palm‑based oils, so the saturated fat is higher than nut‑only bars. A minority of Amazon buyers say the filling can taste a bit artificial, and the chocolate coating can get messy if you’re eating in warm conditions.
The Middle Ground
So, is FITCRUNCH a treat dressed up as a protein bar or a protein bar that tastes like a treat? Both can be true.
If you use it as a small meal or a post‑training refuel, the 380 calories and 30g of protein make sense; if you want a dainty hold‑you‑over snack, it’s overkill. On sweeteners: some people (shout‑out to Redditor casualibrarian) say it doesn’t spike their blood sugar and love the taste; others (Pixieflower and friends) don’t tolerate sugar alcohols at all.
That’s not a “loophole” so much as a labeling approach that reduces added sugar while still contributing carbs—and sometimes stomach rumbling.
One reviewer elsewhere argued only about 12g of the protein “counts,” but that doesn’t line up with how protein digestibility is typically measured; whey remains one of the most digestible proteins we have.
The real trade‑off is clear: incredible flavor and big protein, balanced against higher calories, a long label, more saturated fat, and sweeteners that may or may not love you back.
What's the bottom line?
FITCRUNCH’s Peanut Butter bar is the rare high‑protein option that genuinely eats like dessert. It packs 30g of whey‑forward protein into a layered, candy‑bar‑style bite and keeps most people full for hours. If your goal is to replace a quick meal or refuel after training and you prioritize taste, it’s a winning pick.
Know the compromises: the full‑size bar is calorie‑dense, leans on sugar alcohols, and brings more saturated fat than nut‑only bars. If you’re sensitive to polyols or prefer short, whole‑food labels, look elsewhere. But if you want big protein without a blender—and a flavor that makes you actually want to eat your protein—this is one of the most enjoyable ways to do it.
