MET-Rx
Vanilla Caramel Churro
TL:DR
In 2 Sentences
A truly big, meal‑leaning bar: ~30g of protein, about 380 calories, and a heavy dose of added vitamins/minerals wrapped in a dessert‑style flavor. The multi‑source protein (soy, dairy, egg) gives it a strong amino acid profile compared with single‑source bars.
When to choose MET-Rx Vanilla Caramel Churro
Reach for it when you’ve missed a meal, need post‑workout recovery, or want something sweet that actually keeps you full. Skip it if you’re aiming for minimal ingredients, lower added sugar, or if you avoid soy, dairy, egg, or nuts.
What's in the MET-Rx bar?
MET‑Rx’s Big 100 Vanilla Caramel Churro leans into dessert-shop nostalgia while packing a serious protein punch. Its METAMYOSYN blend starts with soy protein crisps and layers in whey and milk protein isolates plus egg white—an animal‑and‑plant combo that drives a top‑tier protein number.
The flip side: this bar also sits near the high end for carbs, sugar, and calories, delivering meal‑like energy rather than a light snack. That churro‑caramel profile is built with cinnamon, classic sugars and syrups (corn and brown rice), and creamy notes from yogurt powder, butter, and heavy cream.

Protein
3015HIGHThe 30g of protein come from a mixed stack: soy protein crisps do much of the lifting, backed by whey isolate/concentrate, milk protein isolate, and even egg white. Dairy proteins bring top‑tier amino acids and fast uptake, soy fills in with a complete plant source, and egg adds structure—all highly refined rather than whole‑food proteins. Expect strong muscle support, with milk and egg allergens in the mix and generally low lactose thanks to the use of isolates.
Fat
119MIDFat here is a blend of fractionated palm kernel/palm oil (more saturated), dairy fats (butter, heavy cream), and unsaturated sources like canola oil and almond butter. That mix skews more saturated than bars built on olive oil or all‑nut butters, while still offering some heart‑friendly mono‑ and polyunsaturates. At 11g, it contributes creaminess and staying power but is not an “olive‑oil bar” by any stretch.
Carbs
4720HIGHMost carbs are refined and fast: sugar, corn syrup (glucose‑rich), and brown rice syrup (very high glycemic) provide quick burn rather than slow, steady fuel. Sweetness is also padded with a sugar alcohol (maltitol) and glycerin—a moisture‑holding syrup—plus a touch of tapioca starch from the crisps; a little oligofructose adds prebiotic fiber. Net effect: rapid energy with some smoothing from the bar’s protein and fat; sensitive stomachs may notice polyols if you stack them through the day.
Sugar
224HIGHThe 22g of sugar are mainly from refined sources—sugar, corn syrup, brown rice syrup, and brown sugar—fitting the caramel‑churro brief. Additional sweetness comes from a sugar alcohol (maltitol) and glycerin, which lower the labeled sugar grams but still add carbs and can cause GI rumbling in higher amounts. There’s little in the way of fruit‑based sugars here, so expect a classic candy‑bar style sweetness and a brisk rise in blood sugar.
Calories
380210HIGHAt 380 calories, this reads more like a small meal. Roughly 120 calories come from protein and about 100 from fat; the rest is largely from sugars/syrups and polyols. If you need a substantial refuel—long work shift, missed lunch, or a big session—this makes sense; for a quick tide‑me‑over, it’s more than most people need.
Vitamins & Minerals
According to the label, this bar is heavily fortified—standouts include vitamin A and C plus notable minerals like calcium and iron, with additional high hits (such as zinc and copper) typical of a vitamin‑mineral premix. Dairy ingredients (milk protein isolate, yogurt powder) naturally contribute some calcium and phosphorus, but the big percent‑DV numbers point to added micronutrients. In short: protein bar meets multivitamin, with most of the micronutrients coming from fortification rather than whole‑food levels alone.
Additives
To hold everything together, the formula leans on modern bar tech: sugar alcohols (maltitol) and glycerin for sweetness and moisture, emulsifiers like soy lecithin and mono‑/diglycerides for texture, and stabilizers such as xanthan gum and sodium phosphate. These are highly refined, functional ingredients that create that chewy, shelf‑stable bite and creamy coating. Handy for structure and longevity, though less “minimalist pantry” and more ultra‑processed.

“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 keep coming back for three things: protein, fullness, and flavor. Redditor CalypsoBrat buys Big 100s for the 30–32 grams of protein and because they’re “quite tasty,” while CriticalLootRNG calls them a solid fit for an active, high‑calorie day.
On Amazon, Mark says they “taste great and keep you full,” and Alex ranks several flavors highly, praising the rare combo of 30g protein, substantial size, and macros that actually stand in for a meal.
Media nods line up with that experience: LIVESTRONG highlights Big 100 as a legit meal‑replacement option for those who need calories and protein, and Men’s Health names it a best high‑calorie pick for convenience and crave‑able taste.
For many, it’s the dependable, sweet, portable meal you can throw in a bag and forget—until you’re very glad it’s there.
Main Criticism
The sugar and overall sweetness are the loudest complaints. As Reddit user im_a_dick_head bluntly put it, there’s “a shit ton of sugar/sat fat,” and several reviewers note the bar can taste like amped‑up cereal rather than a tempered dessert.
The texture can be polarizing too—an Amazon reviewer warned it’s “very hard,” and another flagged inedible chunks and poor customer support, while a separate review alleged underweight bars in a box.
Taste isn’t universally loved; Quilterski mentions a slight chemical note, and Dan Ayd found one flavor super sweet and artificial. For some stomachs, the inclusion of a sugar alcohol (maltitol) is a GI gamble, especially if you’re stacking other sweeteners throughout the day.
And at 380 calories, it can overshoot what some people want from something labeled a “bar. ”
The Middle Ground
So where does the truth land?
If you treat MET‑Rx Big 100 as a snack, it’s easy to see the pushback—22g of sugar in this flavor, refined syrups, and a big calorie load are a lot for a between‑meal nibble.
But if you treat it like a meal replacement, the numbers make sense: 30g protein, about 11g fat, and a hefty carb dose offer fast energy plus muscle support, with the protein and fat helping blunt the sugar’s impact a bit.
The protein quality is a real strength—dairy plus soy and egg gives a robust amino profile—though it comes wrapped in modern bar tech and a very sweet churro‑caramel package. Texture is hit‑or‑miss: some love the chewy‑crispy layers; others, like Amazon’s “be careful with your front teeth” reviewer, find it too firm.
And yes, the sugar commentary from Reddit (including the user with the most memorable handle on the internet) isn’t wrong; it’s high for a protein bar, though that can be a feature rather than a bug if you need the calories.
The open question is fit: are you replacing a meal or replacing a cookie? One works a lot better than the other.
What's the bottom line?
MET‑Rx Big 100 is the bar you buy when you want your snack to do lunch’s job. It’s sweet and substantial, with 30g of protein from a mixed blend, about 380 calories, and a heavily fortified label that plays like a two‑for‑one: protein bar meets multivitamin. Reviews and expert roundups largely agree—it’s a clutch option for long days and post‑workout recovery, especially if you like dessert‑leaning flavors.
Just go in clear‑eyed. The Vanilla Caramel Churro flavor brings around 22g of sugar and refined syrups, plus ultra‑processed binders that build that chewy, shelf‑stable bite. If your goals or stomach prefer lower sugar or simpler ingredients, this won’t be your everyday bar.
But if you need portable calories that actually keep you full—and you’re fine with soy/dairy/egg (and traces of nuts)—it’s an honest, hearty choice. Condensed listicle take: Big, sweet, 30g‑protein meal‑in‑a‑bar that shines when you need real calories; watch the added sugar, firmness, and ultra‑processed build.
