Grenade
OREO Protein Bar
TL:DR
In 2 Sentences
An official Oreo collaboration with a layered, candy‑bar texture that delivers 21g of milk‑based protein and just 1g of sugar—engineered to taste like a treat without the sugar rush.
When to choose Grenade OREO Protein Bar
Best for cookies‑and‑cream lovers who want a satisfying post‑workout or afternoon snack with real staying power. Less ideal if you’re sensitive to sugar alcohols or need gluten‑free.
What's in the Grenade bar?
Here’s the short story of Grenade’s OREO Protein Bar: big‑league protein from milk (casein plus whey isolate) with a touch of collagen; almost no sugar thanks to engineered sweeteners; and an Oreo-style experience built from real cocoa, a milk‑chocolate coating, and a wheat‑based cookie layer that’s alkalized for that deep, dark cookie flavor.
Macros land in substantial‑snack territory—21g protein sits near the top of the charts, carbs are about average but drawn mostly from refined ingredients, and fat is mid‑range from a blend of palm, canola, and cocoa butter.
If you want cookies‑and‑cream without a sugar bomb, this delivers it—just know the sweetness leans on sugar alcohols and fiber rather than fruit or whole grains.

Protein
2115HIGHProtein comes primarily from a dairy blend of calcium caseinate and whey protein isolate, with a smaller dose of bovine collagen. The milk proteins are complete and highly digestible—whey is low in lactose and fast‑acting, while casein digests more slowly—so they do the heavy lifting for the 21g total. Collagen helps texture but is incomplete on its own, so think of it as support rather than the star.
Fat
109MIDThe 10g of fat comes from palm oil, rapeseed (canola) oil, cocoa butter in the chocolate, and dairy. That means a mix of saturated fats (palm, cocoa butter) and heart‑friendlier unsaturated fats (canola). It’s a moderate amount for a bar; if you prioritize nuts or olive oil, this skews more confectionery‑style.
Carbs
2020MIDMost carbs come from an Oreo‑style cookie layer built with refined wheat flour and wheat starch, then rounded out with polydextrose (a manufactured soluble fiber), maltitol (a sugar alcohol), and a little glycerol for softness. This is more engineered than whole‑grain or fruit‑based carbs; the fiber and sugar alcohols keep sugar low and can blunt sharp spikes for many people. If you’re sensitive to sugar alcohols, one bar is usually fine, but multiple servings may feel gassy.
Sugar
14LOWOnly 1g of sugar, likely from dairy (lactose) in the milk chocolate and milk ingredients. Sweetness instead relies on sugar alcohols—chiefly maltitol—for bulked sweetness, with a pinch of sucralose to sharpen it, and polydextrose/glycerol adding body. That keeps blood sugar lower than a candy bar, but sugar alcohols can bother sensitive stomachs at higher intakes.
Calories
233210MIDAt 233 calories (a bit above average), the load is split largely between protein and fat, with the remaining energy from refined starches and lower‑calorie bulking sweeteners. Low sugar doesn’t equal low energy—maltitol, glycerol, and polydextrose still contribute calories, just fewer per gram than sugar. Net effect: satisfying for a snack or post‑workout bite, not a diet bar.
Vitamins & Minerals
There are no standout vitamins or minerals over 10% Daily Value. Expect a little calcium from the milk proteins and trace minerals from cocoa, but this bar is built for macros, not micros.
Additives
This is a highly engineered bar: polydextrose and glycerol keep it moist and add bulk, maltitol and sucralose provide sweetness with minimal sugar, and soy lecithin smooths the chocolate. Sodium hydroxide appears as a processing aid to give the cookie pieces that classic deep cocoa color. If you prefer short, whole‑food ingredient lists, note that several components here are highly refined.

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 lead the applause. Reviewers repeatedly say it eats like a candy bar—crunch, cream, and chocolate—without the syrupy sweetness or chalky aftertaste that tanks so many protein bars.
Reddit threads call it a top‑tier option, with some folks noting it’s the only bar they don’t burn out on halfway through a box. The macro story backs the hype: 21g of complete milk protein in a compact, dessert‑leaning format that feels indulgent yet purposeful.
Publications like The Independent and The Standard single out the Oreo flavor specifically for nailing that biscuit‑meets‑cream profile while staying low in sugar. Add in the broader flavor bench across Grenade’s lineup, and fans feel spoiled for choice.
Main Criticism
Not everyone tastes ‘Oreo. ’ A vocal minority finds the bar too chewy or a bit “cardboard‑y,” with one Redditor going full‑poet and calling it “chewy talcum powder.
” Another recurring theme: digestive grumbles. The sweetness relies on sugar alcohols and refined fibers; a single bar is fine for most, but double up and some people feel gassy.
There are also isolated reports of mouth itchiness—likely individual sensitivity to components like milk, soy lecithin, cocoa, or certain sweeteners—which is a reminder to check labels if you know you react to processed sweeteners or dairy.
And if you prefer short, whole‑food ingredient lists, this is not that bar.
The Middle Ground
How do we square “tastes like a real Oreo dessert” with “meh, cardboard”? Start with expectations.
This is a highly engineered bar that uses a wheat‑based cookie layer, milk chocolate, and a blend of sweeteners to mimic an Oreo experience while keeping sugar to a sliver. If you’re used to fruit‑and‑nut bars or minimally processed ingredients, the texture and sweetness profile can read synthetic.
But if your mental benchmark is a candy bar, Grenade’s layering feels impressively close. On the GI front, both camps can be right: sugar alcohols do help keep sugar low, but they can also bloat sensitive folks—especially if you stack bars.
And while some flavors in the range are merely good, even skeptics often concede Oreo (and occasionally White Chocolate Salted Peanut) hits above average. As for performance cred, media outlets note Informed Sport certification on Grenade bars; smart move is to check your specific wrapper.
The truth lives in the middle: it’s a skillful dessert‑style protein bar with compromises typical of its category.
What's the bottom line?
Grenade’s OREO Protein Bar is a clever answer to the eternal question: can a protein bar satisfy a sweet tooth without the sugar rollercoaster? With 21g of complete milk protein and a layered, candy‑bar build, it’s one of the more convincing “treat‑without‑the‑treat” options—and at about 233 calories, it functions as a substantial snack or post‑workout bite, not a dainty diet bar. If you love cookies‑and‑cream and prize taste as much as macros, it’s an easy yes.
Know the trade‑offs. The ingredients are engineered rather than whole‑food simple, and the sweetness leans on sugar alcohols and refined fibers; most people tolerate one bar well, but some get gassy if they overdo it. It contains milk and wheat (plus soy lecithin in the chocolate), so it’s not for those avoiding dairy or gluten.
Flavor‑wise, Oreo is widely praised, though texture and “authentic Oreo” expectations split the room. Net net: a dessert‑leaning protein bar that punches well above its weight on enjoyment, provided you’re comfortable with a modern, formulated ingredient list.
Listicle blurb: Grenade OREO Protein Bar — A convincing cookies‑and‑cream candy‑bar dupe with 21g protein and just 1g sugar. Great for post‑workout or a treat‑like afternoon snack; skip if you’re sensitive to sugar alcohols or need gluten‑free.
