FITCRUNCH
Peanut Butter & Jelly
TL:DR
In 2 Sentences
A true candy-bar experience—layers, crunch, jammy streaks—paired with top-tier protein (30 grams) in the full-size PB&J, making it one of the most indulgent yet high-protein options on the shelf.
When to choose FITCRUNCH Peanut Butter & Jelly
Best for taste-first protein seekers who want a mini meal after training or a satisfying, high-protein dessert swap. Less ideal if you avoid sugar alcohols or prefer short, whole-food ingredient lists.
What's in the FITCRUNCH bar?
FITCRUNCH’s Peanut Butter & Jelly bar reads like a high‑protein candy bar: 30g of protein (99th percentile) from a whey isolate/concentrate blend plus soy protein isolate, all draped in a peanut‑butter base with a jammy look created using natural colors (beet, spirulina, grape juice) and a sweet, chewy matrix.
The flip side of that dessert‑like texture is 22g fat—largely from palm and palm kernel oils—pushing calories to 400 (also near the top of the category), while carbs sit mid‑pack but lean on engineered sweeteners rather than fruit.
In short: massive whey‑led protein, classic PB flavor, and a very processed ingredient list that delivers indulgence and staying power more than minimalist, whole‑food simplicity.

Protein
3015HIGHProtein here is driven primarily by whey protein isolate and concentrate, backed by soy protein isolate and smaller contributions from sodium caseinate, peanut flour, and gelatin. Whey is a complete, highly digestible dairy protein; pairing it with soy (also complete, though slightly lower in amino‑acid quality) gives a robust blend that digests at different speeds. The result is a top‑tier 30g of protein with both dairy and soy clearly in the mix.
Fat
229HIGHMost of the 22g fat comes from palm kernel oil and palm oil that create the bar’s firm, candy‑bar bite, with added fats from peanuts/peanut butter and small amounts of soybean and sunflower oils. Palm fats skew saturated (firm and shelf‑stable), while the peanut and seed oils bring mostly unsaturated fats—the overall profile leans saturated. If you watch saturated fat, know this is one of the richer bars in the aisle.
Carbs
2320MIDCarbs are built from highly processed sweeteners and binders: maltitol and sorbitol (sugar alcohols) and glycerin provide bulk and sweetness, while glucose syrup, dextrose, and a little sugar add fast‑burning carbs. Expect some quick energy from the glucose/dextrose portion, blunted by the bar’s fat and protein; polyols help keep sugar grams low but can upset sensitive stomachs if you stack servings. These are ‘engineered’ carbs rather than whole‑food sources like oats or fruit.
Sugar
24MIDSugar is low at 2g because sweetness and chew come mainly from sugar alcohols (maltitol, sorbitol), glycerin, and a touch of sucralose, with smaller inputs from glucose syrup/dextrose and sugar in the peanut butter. That keeps labeled sugar down but relies on highly refined sweeteners rather than fruit. If you’re polyol‑sensitive, pace your intake and see how you feel.
Calories
400210HIGHAt 400 calories (near the top of the category), this is a mini‑meal. Roughly half the calories come from fat, about 120 from protein, with the remainder from carbohydrates and sugar alcohols. The calorie density tracks the candy‑bar texture: lots of fat, lots of protein, and modestly contributing carbs.
Vitamins & Minerals
There aren’t vitamin standouts; the panel shows about 10% Daily Value iron and small amounts of calcium and potassium. The iron likely comes from soy protein isolate and peanut ingredients, while dairy proteins contribute the modest calcium/potassium. Added vitamin A palmitate and beta‑carotene appear primarily for color/stability rather than to deliver high DVs.
Additives
This recipe is heavily engineered: multiple sweeteners (maltitol, sorbitol, glycerin, sucralose), several emulsifiers (mono‑ and diglycerides, propylene glycol monoesters, lecithins), preservatives (potassium sorbate, cultured dextrose), and colorants, including titanium dioxide alongside beet/spirulina extracts. These keep the bar soft, glossy, and shelf‑stable, but they’re highly refined rather than whole‑food ingredients. If you prefer short, pantry‑style labels, this sits at the opposite end of the spectrum.

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.
Redditor organicchunkysalsa put it simply after breakfast: “They taste really really good,” and several others compare FITCRUNCH to a candy bar in the best way—one even said it’s reminiscent of a Reese’s.
That’s echoed at scale on Amazon, where the bar holds a 4. 4 average with 70% five-star reviews; fans call it filling, genuinely enjoyable, and an easy protein boost.
The protein number itself earns real applause: 30 grams in the full-size PB&J gives you a no-guesswork hit for recovery or a late-afternoon anchor when you need something substantial. Some users also note gentler blood sugar responses than they expected for something so dessert-like—one Costco shopper even said it didn’t spike them—though that’s highly individual.
Main Criticism
There’s no getting around the heft: roughly 400 calories and a saturated-fat-leaning profile put this at the rich end of the bar aisle. Multiple reviewers (and Mashed) flag that it reads more like a dessert than a daily snack, nutrition-wise.
The sweetener strategy—relying on sugar alcohols like maltitol and sorbitol—helps keep labeled sugar low, but several Redditors and Amazon buyers say those ingredients upset their stomachs. A few also call the flavor “a bit artificial,” and some fitness voices argue the macros and ingredients aren’t as performance-oriented as the taste suggests.
The Middle Ground
So which is it—clever fuel or candy? The truth lives in the use case.
If you treat the full-size PB&J as a mini meal, the 30 grams of whey-and-soy-based protein plus a satisfying, layered texture can be exactly what you want after training or on a long day.
If you need a lighter snack, FITCRUNCH also makes smaller bars that fans on Reddit cite at around 190 calories and 16 grams of protein; the experience stays fun, the math gets gentler.
On the ingredient side, this is not a minimalist label: expect engineered sweeteners, stabilizers, and even colorants (titanium dioxide among them, which is controversial in the EU but still permitted in the U.
S. ).
That doesn’t make the bar “bad,” but it’s a different philosophy than oats-and-nuts simplicity. As for the bold claim from one reviewer that only about 12 grams of the protein is “bioavailable”—that’s a reach.
Whey and soy are both high-quality proteins; without a tracer study, cutting a 30-gram dose down to 12 isn’t supported. Meanwhile, the GI concerns are real for some: sugar alcohol tolerance varies widely.
If you’re polyol-sensitive, you might love the taste but not the aftermath.
What's the bottom line?
FITCRUNCH’s PB&J is a pleasure-first protein bar that still brings real numbers. It’s unabashedly engineered for fun—crunchy, creamy, jammy—and it delivers a full shake’s worth of protein in bar form. But the trade-offs matter: high calories for the category, a saturated-fat-leaning profile, and a roster of sweeteners and emulsifiers that won’t please whole-food purists or those with sensitive stomachs.
If you’re a taste-first lifter who wants a post-workout mini meal or a high-protein dessert stand-in, this bar is an easy yes—just treat the full-size like what it is: a small meal. If you want something cleaner, lower in saturated fat, or free of sugar alcohols, keep looking. And if you’re somewhere in the middle, try the smaller FITCRUNCH size, or split a full bar across two snacks.
Either way, set your expectations: joy like a candy bar, protein like a shake, and ingredients that make it possible. Condensed listicle version: Candy-bar taste, heavyweight protein. FITCRUNCH PB&J delivers 30 grams of whey-led protein in a layered, dessert-like bar that eats like a mini meal (~400 calories).
Expect great flavor and serious satiety, plus sugar alcohols and a very processed ingredient list. Best for post-workout or a high-protein treat; skip if you avoid polyols or want a short, whole-food label.
