Grenade
Peanut Nutter - Peanut Butter Protein Bar
TL:DR
In 2 Sentences
A candy-like, triple-layer chocolate–peanut bar that still lands 20g protein and just 2g sugar, achieved with a milk‑protein base, low‑sugar sweeteners, and a touch of collagen for chew—meaning it isn’t vegetarian.
When to choose Grenade Peanut Nutter - Peanut Butter Protein Bar
Chocolate‑peanut lovers who want a post‑workout or afternoon treat that won’t spike sugar or blow calories. Best for people who tolerate sugar alcohols and who eat dairy, soy, and peanuts.
What's in the Grenade bar?
Grenade’s Peanut Nutter layers real peanuts (7%) and a milk‑chocolate coating over a dairy‑led protein blend to deliver a bar that tastes like candy but eats like a protein snack. The protein backbone is mostly milk proteins (whey and casein), supported by soy protein and a touch of bovine collagen for chew.
Carbs lean on low‑sugar sweetening systems—think synthetic fiber and sugar alcohols—rather than oats or dried fruit, which keeps sugars down and energy steadier for many. Fats come from cocoa butter, peanuts, and a little sunflower/soy oil, so you get a mix of saturated, mono‑, and polyunsaturated fats.
If you love chocolate‑peanut flavor, this one gets there with actual peanuts, peanut flavor, and that 19% milk‑chocolate layer sweetened without much sugar.

Protein
2015HIGHThe 20g of protein comes primarily from a dairy trio—milk protein, whey, and calcium caseinate—bolstered by soy protein and a small amount of bovine collagen. Whey and casein complement each other (faster and slower digesting) and together deliver a complete amino‑acid profile; soy is complete too, while collagen is not and is used mainly for texture. Net effect: a high‑quality, milk‑protein‑led bar with a little extra support from plant and collagen peptides.
Fat
99MIDFat here is a blend of cocoa butter from the milk‑chocolate coating, peanuts, and refined seed oils (sunflower and soy). Cocoa butter adds more saturated fat (much of it stearic acid), peanuts bring mostly heart‑friendly monounsaturated fat, and the seed oils contribute polyunsaturated fats that skew omega‑6. The total lands around mid‑pack: flavorful without feeling oily.
Carbs
1820MIDMost carbs come from low‑sugar sweetening and texture systems rather than whole‑food starches: polydextrose (a synthetic soluble fiber made from glucose), maltitol (a sugar alcohol), and glycerol (a plant‑derived moisture holder), plus a little lactose from the milk chocolate and dairy proteins. This combination generally yields a gentler blood‑sugar rise than bars built on syrups or fruit purees. If you’re sensitive, know that sugar alcohols and certain fibers can cause gas or urgency at higher intakes—start with half a bar to test your tolerance.
Sugar
24MIDSugar stays very low (1.7g), mostly from naturally occurring lactose in the chocolate and milk proteins. Sweetness instead comes from sugar alcohols (chiefly maltitol, which has fewer calories than sugar) plus a tiny dose of sucralose, an intense no‑calorie sweetener. That keeps sugars down and glycemic impact modest, though some people prefer to limit artificial sweeteners and may notice GI effects from polyols.
Calories
218210MIDCalories are right around the category average, with protein and fat doing much of the work. The carb number slightly overstates energy impact because several grams come from fiber and sugar alcohols that provide fewer calories than sugar. Translation: solid satiety from protein and fat, without a dessert‑level calorie load.
Vitamins & Minerals
No added vitamins are flagged, and nothing stands out above 10% Daily Value. You’ll still pick up small amounts of calcium and riboflavin from the milk proteins, a bit of vitamin E from sunflower/soy oils, and minerals like magnesium from cocoa and peanuts—but consider these nice extras rather than the reason to buy the bar.
Additives
To make a low‑sugar bar that stays soft, this formula uses polydextrose (a synthetic fiber for bulk), glycerol (a moisture‑keeper), soy lecithin (an emulsifier for smooth chocolate), and a sweetener system that pairs maltitol (a sugar alcohol) with a pinch of sucralose. These are highly refined ingredients that deliver sweetness, structure, and shelf life. Most people tolerate them fine in moderation, but polyols can bother sensitive stomachs if you eat multiple servings.

“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 are the headlines.
Across Reddit and Amazon, fans keep calling Grenade one of the few protein bars that actually eats like a candy bar—layered, chocolate‑coated, and without the chalky aftertaste that sinks a lot of competitors.
Several reviewers put Grenade in their personal top three, praising how flavors feel distinct rather than “same bar, different wrapper. ” The macro profile—20g protein for ~218 calories with very low sugar—gets consistent applause from people who want a sweet fix after a lift or between meetings.
Independent outlets echo the sentiment, with The Independent and The Standard both highlighting how indulgent it tastes while staying macro‑friendly. In short: reliable flavor, satisfying texture, goal‑aligned numbers.
Main Criticism
Not everyone is sold on the chew. A minority of Redditors describe certain flavors as overly dense or even “cardboard‑y,” and one particularly dramatic comment called it “chewy talcum powder.
” Sweetness comes from sugar alcohols and a tiny amount of sucralose, which some people avoid on principle or for GI comfort; a few users report gas or urgency if they eat multiple bars.
There’s also the occasional mouth‑itch anecdote—likely an individual sensitivity, but worth noting in a bar that contains dairy, soy, and peanuts. And while many flavors shine, reviewers do call out inconsistency: a couple are home runs; others are fine but forgettable.
The Middle Ground
So which is it: dessert‑level delicious or dense and disappointing? The truth lives in the middle.
If you like layered, candy‑bar textures and don’t mind a firmer chew (common in low‑sugar bars that use fiber, collagen, and sugar alcohols for structure), Peanut Nutter lands squarely in the “treat that fits your macros” camp.
If you want soft, bakery‑style bars or whole‑food ingredients, you may side with the “cardboard” crowd. The sweetening system is a conscious trade‑off: keeping sugars at 2g means leaning on maltitol and a touch of sucralose; that’s great for many, but not for everyone’s stomach.
Flavor‑wise, Grenade is consistently better than average, with standouts that reviewers rave about—though Reddit being Reddit, someone will always claim it’s the worst thing since unsalted rice cakes. Also note the nuance often missed in glowing write‑ups: there’s bovine collagen in the mix, which improves texture but makes the bar non‑vegetarian.
What's the bottom line?
Peanut Nutter is Grenade doing what it does best: a chocolate‑peanut bar that genuinely tastes like a treat, yet still delivers 20g of milk‑led protein in about 218 calories with only 2g of sugar. It’s built for post‑workout cravings and afternoon slumps when you want something candy‑adjacent without the sugar crash. The caveats are straightforward.
The chew is on the firmer side compared with syrup‑heavy bars, the sweetness comes from sugar alcohols and a pinch of sucralose, and the collagen means it’s not vegetarian. If you tolerate those ingredients and you’re okay with dairy, soy, and peanuts, this is a strong, dependable pick. If your priority is short, whole‑food ingredient lists—or you’re sensitive to polyols—look elsewhere.
Otherwise, enjoy the peanut‑chocolate payoff with macros that play nice. 20g protein, ~218 calories, 2g sugar, with low‑sugar sweeteners and a touch of collagen (not vegetarian). Great for post‑workout or sweet‑tooth moments; skip if sugar alcohols bother you or you avoid dairy/soy/peanuts.
