Grenade
Peanut Butter and Jelly Protein Bar
TL:DR
In 2 Sentences
A triple-layer, candy-bar-style protein bar that keeps sugar low while packing 21g of milk‑based protein—plus a wide flavor lineup (Oreo gets a lot of love) that genuinely leans indulgent. It’s built for taste-first athletes and sweet-tooth snackers who still care about macros.
When to choose Grenade Peanut Butter and Jelly Protein Bar
Reach for this after a workout or when an afternoon craving hits and you want dessert energy without a sugar crash. Best for people who tolerate sugar alcohols and like a chocolate-coated, layered texture over a simple, whole‑food style bar.
What's in the Grenade bar?
Grenade’s Peanut Butter and Jelly Protein Bar wears a chocolate coat but thinks like a protein shake. The muscle support comes from a milk‑based blend—calcium caseinate and whey isolate—backed by a little bovine collagen for chew, landing this bar in the top tier for protein.
The PB&J theme is built with roasted peanut pieces and peanut flavor on the “PB” side, raspberry powder (plus a touch of fruit-and-veg concentrate for color) on the “J,” while low sugar is achieved by swapping table sugar for sugar alcohols in the chocolate layers.
Carbs sit around the middle of the pack, fats run a bit higher thanks to cocoa butter, palm fat, and peanuts, and the result tastes like dessert but eats like a substantial snack.

Protein
2115HIGHThe protein heavy lifting comes from milk proteins—calcium caseinate and whey protein isolate—providing a complete amino‑acid profile with a mix of slow (casein) and fast (whey) digestion. A smaller amount of bovine collagen helps the texture but isn’t a complete protein on its own. With 21g, this bar sits near the top of the category for protein density.
Fat
109MIDAbout 10g of fat is driven by cocoa butter and palm fat in the chocolate layers, with peanuts contributing additional fat. That mix leans more saturated than a nut‑only bar, though the peanuts add some heart‑friendly unsaturated fats. If you aim to prioritize unsaturated oils, note the coatings tilt the profile toward creamy, saturated fats.
Carbs
2020MIDThe 20g of carbs are mostly engineered rather than from whole grains: sugar alcohols in the chocolate for sweetness, glycerol to keep the bar soft, and added fiber (polydextrose), with smaller contributions from dairy lactose and the raspberry powder’s maltodextrin carrier. This combo usually softens the blood‑sugar rise compared with regular sugar, while the fiber helps with fullness. The trade‑off: maltodextrin is a quick carb, and sugar alcohols can bother sensitive stomachs in larger amounts.
Sugar
24MIDSugar stays low at 1.7g because most sweetness comes from sugar alcohols (in the milk and white chocolate) and a small amount of glycerol rather than table sugar. You still get sweetness with fewer sugar calories, though some people find sugar alcohols cause gas or bloating if they overdo it. Any natural sugars here mainly come from dairy lactose and the berry powder—and they’re minimal.
Calories
232210MIDAt 232 calories, this is a substantial snack where calories are shared across all three macros: sizable protein, notable fat from chocolate and peanuts, and moderate carbs. The chocolate coatings and added fats do some heavy lifting in the total, making it feel closer to a mini meal than a light bite.
Vitamins & Minerals
No standout vitamin or mineral amounts are listed over 10% Daily Value. Expect small contributions—calcium and B vitamins from dairy, a touch of vitamin E from peanuts, and trace minerals and polyphenols from cocoa and berries—but this bar is built for protein, not fortification.
Additives
To achieve low sugar and a soft bite, the bar leans on modern helpers: polydextrose (added fiber and body), glycerol (moisture), lecithin (keeps chocolate smooth), and sugar alcohols (sweetness with fewer sugar calories). The raspberry powder includes maltodextrin, a refined starch, as a carrier. It’s more processed than a nut‑and‑date bar—typical for chocolate‑coated, low‑sugar protein bars.

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 is the headline. Across Reddit and Amazon, people keep calling Grenade one of the few bars that actually feels like a candy bar—layers, crunch, chocolate, the whole production—without the usual protein-bar aftertaste.
Several commenters even rank it top tier for flavor variety, with Oreo and White Chocolate Salted Peanut repeatedly singled out as standouts. The macros land well, too: around 21g of protein at roughly 232 calories is a solid ratio for post‑training or a substantial snack.
Reviewers also note the mixed textures—crisp bits plus a soft center—as a big reason it avoids the “chalky slab” trap. And mainstream outlets echo this: both The Independent and The Standard praise Grenade for tasting indulgent while keeping sugar notably low.
Main Criticism
Not everyone is wooed by the chew. A slice of commenters find Grenade bars dense or “cardboard‑y,” especially when expectations are set to full-on candy bar.
Flavor hits can be uneven—there are clear winners, and a few that people call forgettable. The low sugar comes with a trade-off: sugar alcohols.
For many, they’re fine; for some, gas and bloating are very real if you stack bars or have a sensitive gut. A small number of users also report odd mouth sensations or itchiness, which could reflect individual sensitivities to ingredients like peanuts, dairy, or certain sweeteners.
The Middle Ground
So who’s right—the dessert devotees or the texture skeptics? Probably both, depending on what you expect from a protein bar.
Grenade’s engineering is deliberate: milk proteins for a strong amino profile, chocolate coatings for that “real treat” experience, and low sugar supported by sugar alcohols and added fiber. If you want a date-and-nut bar with only pantry staples, this isn’t it.
But if you want a chocolate-coated bar that tastes like something you might sneak into a movie theater, this is exactly its lane. Flavor-wise, crowd favorites (Oreo, White Chocolate Salted Peanut) are reliably praised, while others fall into “fine, not fantastic.
” And on digestion: if sugar alcohols bug you, the solution isn’t wishful thinking—it’s moderating your intake or choosing a different style of bar. The truth lives in the middle: Grenade excels at tasting indulgent while hitting useful macros, provided its particular ingredient playbook works for you.
What's the bottom line?
7g of sugar, and a layered, chocolate-coated bite that satisfies an honest sweet tooth. It’s designed for enjoyment first and minimal sugar second, with enough protein to matter after a workout or as a sturdy snack. The trade-offs are clear.
You’re getting modern sweeteners and a richer fat profile from chocolate and peanuts, not a minimalist, whole‑food ingredient list. If sugar alcohols treat you kindly and you like a candy-bar texture, this is a standout pick—especially in the flavors fans rave about. If you’re sensitive to sugar alcohols or prefer simpler bars, you’ll want a different tool for the job.
7g sugar, and layers that actually taste indulgent. Best for post‑workout or afternoon cravings—just note the sugar alcohols if your stomach runs sensitive.
