MET-Rx
Salted Caramel Brownie Crunch
TL:DR
In 2 Sentences
A true meal-replacement style protein bar: roughly 390 calories with 30g of protein, layered like a candy bar but built for recovery and staying power.
When to choose MET-Rx Salted Caramel Brownie Crunch
Best for high-output days, missed-meal moments, and post-workout recovery when you want something filling, sweet, and portable—not for folks chasing ultra-low sugar or minimalist ingredients.
What's in the MET-Rx bar?
MET-Rx Salted Caramel Brownie Crunch is built like a small meal: 30g of protein from a multi-source blend (whey and milk proteins, soy crisps, and a touch of egg white), paired with big, dessert-leaning carbs and a confection-style fat mix.
The brownie notes come from alkalized cocoa, unsweetened chocolate, and cocoa butter, while the salted-caramel vibe is driven by natural flavor with caramel color, butter/cream, and a pinch of salt. It lands near the top of the category for protein—and also for carbs, sugar, and calories—so think of it as a hearty, candy-bar-adjacent fuel rather than a minimalist, whole-food snack.

Protein
3015HIGHThirty grams is elite for a bar, and it’s delivered by a mixed matrix: whey protein isolate and concentrate plus milk protein isolate (casein + whey) for fast-and-slow digestion, with soy protein isolate in the crispy bits and a little egg white rounding it out. The isolates keep lactose relatively low while providing complete amino acids, though they’re highly refined and bring milk, soy, and egg allergens. The blend suits recovery and satiety, but it’s more engineered than whole-food–based.
Fat
129HIGHThe 12g of fat come largely from confection-style fats—fractionated palm kernel and palm oil for structure and snap—plus dairy fats (butter, cream, milkfat) and cocoa butter, with canola oil and a touch of almond butter adding unsaturated fats. Net-net, the profile tilts toward saturated fat, typical of chocolate-coated bars. It’s tasty and stable on the shelf, but if you’re watching saturated fat, note that this mix leans more creamy and palm-based than olive- or nut-forward.
Carbs
4720HIGHThese are mostly refined carbs aimed at sweetness and chew: corn syrup, sugar, rice syrup, and fructose provide quick energy, while maltitol (a sugar alcohol) and glycerin keep the bar soft and sweet with a smaller glucose bump than sugar alone. Starches like tapioca and corn grits add bulk; a touch of fructo‑oligosaccharides adds prebiotic fiber but won’t offset the overall glycemic load. Expect fast fuel rather than slow, whole‑grain steadiness—protein and fat will blunt the spike a bit, but this skews toward quick-burning energy.
Sugar
204HIGHWith 20g of sugar, sweetness is driven mainly by refined sources—sugar, corn syrup, rice syrup, and some fructose—augmented by maltitol and glycerin to keep texture and sweetness high without counting as ‘sugar’ on the label. Corn and rice syrups are high–glycemic, so the taste reads indulgent and the energy hits quickly. If you’re sensitive to sugar alcohols, note that maltitol can cause GI discomfort for some people when portions stack up.
Calories
390210HIGHAt 390 calories, this sits in meal-replacement territory. Roughly 120 calories come from the 30g of protein, about 108 from 12g of fat, and the rest largely from carbohydrates (including syrups and sugars), so most of the energy is carb-led with a meaningful fat assist. Great when you need a substantial, portable bite; overkill if you were after a light snack.
Vitamins & Minerals
Micronutrients here are mostly added: the label’s 30% DV iron, 15% DV calcium, and 10% DV potassium come largely from the vitamin–mineral blend (including calcium and potassium phosphates), with assists from cocoa and dairy. It’s fortification-forward rather than nutrient-dense by nature. Helpful if you’re bridging gaps, but not a substitute for mineral-rich whole foods.
Additives
This bar relies on a long list of modern helpers: maltitol syrup and glycerin for moisture and reduced‑sugar sweetness, emulsifiers (mono‑ and diglycerides, lecithin) for smoothness, sodium phosphate and xanthan gum for stability, and coloring like titanium dioxide. They keep the bar soft, glossy, and shelf‑stable, but reflect a highly refined build rather than a short, kitchen‑style ingredient list.

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
Fans love that this bar actually fills them up. It’s substantial in size and lands closer to a real meal than a tiny snack, which is exactly why Amazon reviewer Mark uses it to power long days.
The protein is elite for a bar at 30 grams, and that matters in the real world—Redditor CalypsoBrat buys Big 100s specifically for the high protein and taste.
Texture and flavor also get frequent nods: the salted caramel brownie flavor is often singled out as balanced and not cloying, and Amazon reviewer Alex called the lineup his go-to for the best mix of taste, texture, size, and macros.
The crispy-chewy interior and chocolate coating read like a treat, which is half the appeal when you’re tired of chalky snacks. For active folks, that dessert-leaning profile doubles as motivation to actually eat enough after training.
Main Criticism
The tradeoff for that candy-bar experience is a meaningful dose of added sugar (around 20 grams in this flavor; some others run higher) and a confection-leaning fat blend that skews saturated.
If you’re trying to keep sugar lower, this won’t be your everyday bar—Eat This, Not That! enjoyed the taste but balked at the sugar for daily use.
A few buyers report texture issues on occasion—some bars show up quite firm, even hard to bite, and one Amazon reviewer flagged odd, inedible chunks in a batch (a quality-control miss).
There’s also the engineered ingredient list and the use of sugar alcohols like maltitol, which can bother sensitive stomachs when portions stack up. And because the protein comes from milk and soy with a touch of egg, those allergens rule it out for some.
The Middle Ground
So where does the truth settle? If you read the room, you’ll see two camps: the “I need a real meal in my pocket” crowd and the “please keep my bar light and simple” crowd.
Men’s Health crowned Big 100 a best high-calorie pick precisely because it’s large and protein-dense; Redditor CriticalLootRNG echoes that sentiment, saying the calories and protein fit a bike commute and frequent workouts.
On the other side, Eat This, Not That! liked the crispy-chewy layers but wouldn’t buy regularly because 20 grams of added sugar doesn’t fit their goals.
Redditor im_a_dick_head put it less delicately—calling out the sugar and saturated fat—while GranolaBarHero shrugged, “doesn’t taste particularly good, doesn’t taste particularly bad. ” All of them are right for their contexts.
The nutrition here is engineered for fast fuel and big protein, not for a short, whole-food ingredient list or low sugar. If you want a candy-adjacent meal bar to bridge long gaps between meals, it shines; if your priority is minimalist or low-sugar, its strengths read like drawbacks.
What's the bottom line?
MET-Rx Big 100 Salted Caramel Brownie Crunch is unapologetically a meal bar: 30 grams of protein, dessert-like layers, and enough calories to count. It’s built for athletes, busy shifts, travel days, and anyone who needs a satisfying, sweet-leaning way to replace a meal or recover after training. The flipside is the added sugar, palm-leaning fats, and a long, modern ingredient list—including sugar alcohols—that won’t appeal to purists or those chasing low-sugar macros.
It also contains milk, soy, and egg—important if you manage allergens. If you’re skimming: big protein, big satisfaction, big bar. Great for high-output days and post-workout; less ideal if you want low added sugar or a short, whole-foods ingredient list.
