MET-Rx
Super Cookie Crunch
TL:DR
In 2 Sentences
A truly meal-sized bar: around 30–32g of protein per 100g bar with a candy-bar-like build. Super Cookie Crunch is sugar-sweetened (not with high-intensity sweeteners), engineered to be satisfying when you’re actually hungry.
When to choose MET-Rx Super Cookie Crunch
Choose it when you’ll miss a meal, need post-workout recovery on the go, or want a sweet, filling stand-in that still delivers serious protein; skip if low sugar or minimal-ingredient bars are your priority.
What's in the MET-Rx bar?
MET-Rx’s Super Cookie Crunch reads like a protein-forward candy bar: a big 32g hit of protein from a multi-source blend, wrapped in chocolatey, cookie-like texture.
The METAMYOSYN blend pulls from soy protein isolate (in the crispy bits) plus milk protein isolate, whey isolate/concentrate, and a dash of egg white—so you get fast- and slow-digesting proteins in one bite.
That crunch and chocolate flavor come from alkalized cocoa, chocolate, cocoa butter, and cookie-style inclusions bound with sugars and oils, which also drive the bar’s higher carbs, sugars, and calories compared with most protein bars.

Protein
3215HIGHProtein here comes from a mixed team: soy protein isolate (inside the cocoa soy crisps) plus milk protein isolate and whey isolate/concentrate, with egg white in support. Dairy proteins are highly digestible and leucine-rich, while soy brings complete plant protein—together they deliver a robust amino acid profile with relatively little lactose compared to plain milk. The tradeoff is processing: isolates and concentrates are refined ingredients, and the blend includes milk, soy, and egg allergens.
Fat
139HIGHThe 13 grams of fat come from a mix of canola oil (mostly heart‑friendly monounsaturated fat) and more saturated confectionery fats—fractionated palm kernel/palm oils, cocoa butter, and some butterfat—plus smaller contributions from almond butter and peanut flour. Those saturated, shelf-stable fats help create the cookie‑crunch texture and a chocolatey snap, but they skew the fat profile toward saturated fat. Net effect: a functional mix for structure and flavor, not a nuts-and-olive‑oil type fat blend.
Carbs
4220HIGHCarbs are largely “refined” energy: corn syrup (glucose), sugar (sucrose), and fructose, with tapioca starch in the soy crisps and a little chicory‑root–derived oligofructose for fiber. Expect fast fuel and a bigger glycemic push than you’d get from oats or dates; the hefty protein and fat will blunt it somewhat, but this leans more candy‑style than whole‑grain steady. If your goal is sustained, gentle energy, this isn’t your clean‑carb bar.
Sugar
254HIGHSugar is high for a protein bar (25 grams), driven by sugar itself, corn syrup, and added fructose, with a smaller contribution from milk sugars in whey/milk ingredients. There are no high‑intensity sweeteners here—sweetness comes from refined sugars, not fruit. You’ll get quick sweetness and quick energy, not a low‑sugar experience.
Calories
410210HIGHAt 410 calories, this functions more like a compact meal than a light snack. Calories are split across all three macros, with a sizable share from refined carbs and a big contribution from protein, plus confectionery fats that help with texture. Useful when you truly need the energy; overkill if you just want a small between‑meal bridge.
Vitamins & Minerals
The nutrition panel lists notable amounts of vitamin A, vitamin E, thiamin, riboflavin, iron, calcium, and zinc. Some of this can come naturally from dairy proteins (calcium, riboflavin) and cocoa (iron), and there are tocopherols (vitamin E) added to protect flavor. Given the high percentages reported (for example, zinc), part of the micronutrient lift likely comes from fortification—check the package for the full vitamin/mineral listing.
Additives
This is a formulated, long‑shelf‑life bar: glycerin keeps it soft, soy lecithin emulsifies, and xanthan gum stabilizes. Alkalized cocoa delivers smooth chocolate flavor, and fractionated palm oils provide structure without trans fats. These are standard, highly refined tools for texture and shelf stability rather than whole‑food ingredients.

Range
“I buy the Met-RX Big 100 bars because they’re 30-32 grams of protein and they’re quite tasty.”
“I actually buy their cookies n cream bars pretty often. Like the taste, high protein and live an active lifestyle (commute on bike + workout often) so the calories are pretty good for my needs.”
“My favorite of all time it the Met-Rx super cookie crunch bar. 100g Bar for 410 calories, 32g protein, 42g carbs, 14g fat. It’s high in sugar but once in a while it’s my sweet meal. They taste SO good and take me a long time to eat”
Main Praise
The headline is real protein in real portions.
Multiple reviewers, from Reddit user CalypsoBrat to Amazon’s Mark and Alex, praise the bar for being substantial, filling, and useful as an actual meal replacement—rare in a category full of pocket-sized snacks.
The flavor and texture get more love than you’d expect at this size: the crispy-chewy layers hit that candy-bar lane while covering the “protein taste” better than many competitors. The variety helps, too: some flavors (Salted Caramel Brownie Crunch, Vanilla Caramel Churro, and the surprisingly convincing Crispy Apple Pie) win consistent nods for taste.
For athletes, commuters, and anyone who needs portable calories plus 30-ish grams of protein, Big 100 shows up when a small bar just won’t cut it. It’s also appealing if you dislike the cooling aftertaste of sugar alcohols—the sweetness here comes from sugar, which many find more familiar on the palate.
Main Criticism
Sugar is the sticking point. Depending on the flavor, you’re looking at roughly 20–29 grams, and the Super Cookie Crunch clocks in high for the category.
If you’re targeting low added sugar, this isn’t that bar. Texture isn’t universally adored either; a few buyers report very firm bars or tough inclusions—one Amazon reviewer warned to “be careful with your front teeth.
” There are occasional quality-control gripes (odd hard bits, underweight bars) that, while not the norm, are frustrating when you buy by the box. And if you prefer short, whole‑food ingredient lists or nut-and-seed fat sources, the confectionery-style oils and processed protein isolates won’t thrill you.
The Middle Ground
The divide makes sense once you look at intent. Big 100 is built as a portable meal: high protein, enough calories to matter, and a flavor profile that makes you actually want to finish it.
For people like Redditor CriticalLootRNG—who bikes, lifts, and needs energy—those calories are a feature, not a bug. On the flip side, Men’s Health rightly flags the added sugar; if your goal is to keep sugars low day-to-day, this bar will chew through your budget fast.
The texture complaints are also mixed: Amazon Customer’s “hard” warning is worth noting, while a Reddit comment about “RX bars” being too hard likely meant a different brand entirely—so take that one with a grain of cocoa.
The most grounded read is this: it’s a candy-bar-adjacent meal replacement that’s honest about it. Use it when you need the fuel; don’t force it when you don’t.
What's the bottom line?
MET-Rx Big 100 (Super Cookie Crunch included) is the rare protein bar that actually eats like a meal. At 410 calories and 32 grams of protein, it’s a pragmatic choice for long workdays, travel delays, or post-lift refuels when real food isn’t happening. 5-star average across more than 11,000 Amazon ratings.
The tradeoff is straightforward: added sugar and confectionery fats for flavor and structure, plus a highly processed ingredient list with milk, soy, and egg. If you want a light, low‑sugar daily bar or a short-ingredient label, this isn’t your lane. But if your priority is reliable calories, serious protein, and a bar you’ll actually finish, Big 100 does exactly what it says on the wrapper—no more, no less.
