Grenade
Fudged Up Protein Bar
TL:DR
In 2 Sentences
A convincing candy-bar experience built with real cocoa layers, while a whey isolate/casein blend delivers 22 grams of protein in a compact 210-calorie bar. Sweetness leans on sugar alcohols and fiber instead of table sugar, creating that indulgent taste without a big sugar hit.
When to choose Grenade Fudged Up Protein Bar
Choose this bar if you want a dessert-leaning post-workout or 3 p. m.
protein hit and you tolerate sugar alcohols well. Chocolate lovers who prioritize taste over a super-short ingredient list will be happiest here.
What's in the Grenade bar?
Fudged Up leans into real chocolate building blocks—fat‑reduced cocoa powder, cocoa mass, and cocoa butter—punctuated with sea salt for a true fudge-like finish.
Beneath that indulgence is a dairy-centric protein blend of whey isolate and calcium caseinate, with a dash of bovine collagen for chew, delivering a hefty 22 grams per bar (near the top of the category).
Sweetness comes less from sugar and more from maltitol, polydextrose, and a little glycerol, which keeps calories moderate and pushes the carbs toward lower‑glycemic territory—great for steadier energy if you handle sugar alcohols well.

Protein
2215HIGHWhey protein isolate and calcium caseinate do the heavy lifting here, with a small assist from bovine collagen peptides. The dairy duo delivers a complete amino‑acid profile—whey is fast-digesting, casein is slower—while collagen mainly supports texture and isn’t a complete protein. At 22 grams per bar, you’re squarely in high‑protein territory without a chalky finish.
Fat
89MIDFat comes mainly from cocoa butter and a little rapeseed (canola) oil, with minor contributions from milk powder and cocoa mass. Cocoa butter is rich in stearic and oleic acids, and canola brings mostly unsaturated fats—so the mix is more balanced than it sounds. Total fat is modest, enough for a fudgy bite without feeling heavy.
Carbs
1920MIDMost of the 19 grams of carbs come from engineered sweeteners and fibers rather than grains or fruit. Maltitol (a sugar alcohol), polydextrose (a low‑calorie soluble fiber), and a touch of glycerol supply sweetness and chew while blunting big sugar spikes compared with cane sugar. It’s a steadier‑energy approach for many, though larger amounts of polyols can bother sensitive stomachs.
Sugar
14MIDOnly 1.3 grams of sugar, largely natural lactose from dairy and a trace from cocoa. Sweetness instead is driven by sugar alcohols (maltitol) and a bit of glycerol—highly refined ingredients that lower the blood‑sugar hit versus table sugar but still count toward carbs. If polyols tend to upset your stomach, start with one bar and see how you feel.
Calories
210210MIDAt 210 calories, most of the energy is tied to protein and a moderate amount of fat rather than sugar. Because maltitol and polydextrose carry fewer calories than sugar, you get that candy‑bar texture without a calorie surge. Net result: a protein‑forward snack, not a full meal.
Vitamins & Minerals
No vitamins or minerals are called out above 10% Daily Value. Expect small, incidental amounts of calcium and B12 from dairy and a touch of magnesium and iron from cocoa. Reach for this bar for protein, not micronutrients.
Additives
This formula leans on several refined helpers to keep sugar low and the texture indulgent: maltitol for bulked sweetness, polydextrose for fiber and body, glycerol to hold moisture, and soy lecithin to smooth the chocolate. These do their jobs well, but they make the label longer than a simple nuts‑and‑seeds bar. If you prefer minimal processing, keep that in mind.

Range
“Recently, Grenade (protein bar brand) have released an official Oreo flavoured protein bar. It's absolutely incredible. Tastes like a full-fat Oreo dessert with 50g or more of sugar, but only has 1g. I can't tell at all that it's a workout/diet bar. Has no weird aftertaste. Just tastes like what you'd expect a chewy Twinkie/Cadbury bar to taste like.”
“These are SO GOOD! Only protein bar I don’t suddenly find disgusting when I’m half way through the box”
“Probably a top 3 protein bar honestly. Great macros, low sugar, amazing variety of flavors which taste like an actual candy bar.”
Main Praise
Taste and texture headline the love letters.
Across Reddit and Amazon, people say Grenade manages the rare trick of tasting like a candy bar, with several calling out the lack of a weird aftertaste and the way the layers keep it from eating like a chalky brick.
Variety also earns applause: flavors like Oreo and White Chocolate Salted Peanut show up repeatedly as standouts, so it’s easy to rotate without getting bored. The macros add to the appeal—around 22 grams of protein at roughly 210 calories is squarely in the high-protein range without feeling like a meal.
Mainstream reviewers echo the enthusiasm, praising how indulgent it tastes for the numbers. In short: a treat that still advances your protein goals.
Main Criticism
Not everyone vibes with the chew; a minority call some flavors cardboard-y or simply too dense. A few users report that while the hits are excellent, several flavors land as average, so the experience can depend on which bar you pick.
There are also sensitivity notes: one redditor mentioned an itchy mouth, and others point out that sugar alcohols and certain fibers can unsettle digestion if you’re prone to that. None of this is unusual for bars that use refined sweeteners, but it’s worth clocking.
And if you prefer a short list of whole-food ingredients, Grenade’s label will feel more engineered than you’d like.
The Middle Ground
How do we reconcile “top-three bar” with “chewy talcum powder”? Expectations.
Grenade is designed to mimic a layered chocolate bar, and it uses refined sweeteners and fibers to do that while keeping sugar low. If that’s your target, it executes very well—press and plenty of fans single out flavors like Oreo as proof.
If your priority is minimal processing or you’re sensitive to polyols (sugar alcohols your body only partially absorbs), the same ingredients that create the dessert feel can be the dealbreaker. A practical path through the divide: start with a single bar, stick to one serving, and choose a widely loved flavor to test the waters.
Taste is subjective, but the throughline is clear—Grenade trades a short ingredient list for a candy-bar bite and a substantial protein payoff.
What's the bottom line?
Grenade Protein Bar (Fudged Up) is for people who want their protein to feel like dessert. The whey isolate/casein core supplies 22 grams of complete protein at about 210 calories, and the chocolate-forward, layered build scratches the fudge itch without relying on a lot of sugar. The flip side is a longer, more processed label and the use of sugar alcohols and soluble fiber for sweetness; great for keeping sugar modest, not great for sensitive stomachs.
It also contains dairy (and typically soy lecithin), so it won’t suit everyone. If you tolerate sugar alcohols and want a high-protein, chocolate-first bar to stash in your gym bag or desk, this belongs on your shortlist. Start with one bar, pick a fan-favorite flavor, and enjoy the rare protein snack that doesn’t taste like a compromise.
Condensed listicle take: Dessert-style, layered chocolate bar with 22g protein at about 210 calories. Big flavor achieved with sugar alcohols and fiber—best for chocolate lovers who handle polyols; skip if you want minimal ingredients or dairy-free.
