MET-Rx
Crispy Apple Pie
TL:DR
In 2 Sentences
A true meal-replacement bar: roughly 390 calories with 30 grams of protein and a flavor that actually leans into real apple and cinnamon instead of generic “sweet.”
When to choose MET-Rx Crispy Apple Pie
Choose it when you need a substantial, portable meal—long work shifts, travel days, hikes, or heavy training—more than a light snack. Skip if you’re avoiding added sugar or prefer minimalist ingredient lists.
What's in the MET-Rx bar?
MET-Rx Big 100 Crispy Apple Pie tastes like the bakery case because it is built like one: real apple pieces, apple purée and juice concentrates, and a dusting of cinnamon do the heavy flavor lifting, while syrups bind everything into that crispy-chewy bite.
Under the crust, you get a hefty 30 grams of protein from the brand’s METAMYOSYN blend—soy protein crisps plus whey isolate, milk protein isolate, whey concentrate, and egg white—so it is a true meal-replacement style bar.
The flipside is energy density: most of the calories ride in with quick-burning carbohydrates (from corn syrup, sugar, fructose, and fruit concentrates, with some maltitol syrup and glycerin for texture), landing this bar in the high-calorie, high-sugar camp.
A vitamin-and-mineral premix rounds things out (think vitamin A and C, iron, and calcium), making this feel more like a fortified dessert-meets-protein-bar than a minimalist snack.

Protein
3015HIGHProtein comes from a mixed team: soy protein isolate crisps provide structure, while whey isolate, milk protein isolate (casein + whey), whey concentrate, and egg white deliver highly digestible, complete proteins. That blend marries fast-digesting dairy proteins with steadier casein and egg, helping cover both near-term and longer-release amino acids. It is an allergen-rich mix (milk, soy, egg), but from a quality standpoint it is robust, which helps explain the very high 30g per bar.
Fat
99MIDMost of the 9 grams of fat come from palm oils (fractionated palm kernel, palm oil, and palm fat), with smaller contributions from canola oil and almond butter. Palm-based fats skew more saturated (palmitic acid), which is great for a firm, shelf-stable texture but less heart-friendly than fats from olives, nuts, or seeds; the canola and almond butter add a modest unsaturated counterbalance. Overall, the fat level is moderate, but the profile leans processed and saturated rather than whole-food unsaturated.
Carbs
4820HIGHCarbs are dominated by refined sweeteners and concentrated fruit sugars—corn syrup, sugar, fructose, and apple juice/purée concentrates—backed by starches (tapioca and rice) that provide crisp. A little oligofructose (a prebiotic fiber) and some maltitol syrup and glycerin help with texture and slightly temper glycemic punch, but the overall mix is still quick-burning. Expect fast energy more like a dessert or sports chew than slow, whole-grain fuel.
Sugar
294HIGHThe 29 grams of sugar are primarily supplied by corn syrup, table sugar, fructose, and fruit concentrates (apple juice and purée), with dried apples adding a bit of natural fruit sugar. Fruit concentrates behave like added sugar—they are stripped of fiber—so they sweeten more like syrup than a whole apple would. Maltitol (a sugar alcohol) and glycerin add body with fewer calories than sugar, but sensitive stomachs can notice them if eaten in larger amounts.
Calories
390210HIGHAt 390 calories, this is a small meal in bar form. Most of those calories come from carbohydrates, with protein a strong second and fat trailing behind (roughly 192 kcal from carbs, 120 kcal from protein, 81 kcal from fat). If you are hungry and active, that can fit; if you are after a light snack, it is probably more than you bargained for.
Vitamins & Minerals
Vitamins and minerals here are largely from fortification: vitamin A (as retinyl palmitate) reaches about 50% DV and vitamin C (ascorbic acid) hits roughly 20% DV, while calcium (from calcium phosphate/lactate) and iron land near 15–20% DV. Dairy ingredients contribute some calcium and B vitamins, but the big headline numbers come from the added premix. Think of it as a fortified bar rather than a bar naturally high in micronutrients.
Additives
This recipe uses a long tool kit of functional additives to hold texture and flavor: maltitol syrup and glycerin for softness, lecithins (soy/sunflower) as emulsifiers, xanthan gum for stability, and malic acid for a tart apple pop. There is also a vitamin–mineral premix and small helpers like tocopherols to protect oils. It is an ultra-processed formulation; effective for chew and shelf life, though not the pick for minimal-ingredient purists.

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 keep coming back for two things: the protein and the payoff.
Redditor CalypsoBrat summed it up neatly—30 to 32 grams of protein and genuinely tasty—which mirrors a lot of what we saw on Amazon, where the Big 100 line sits at a 4.
5-star average across more than 11,000 ratings.
The Crispy Apple Pie flavor, in particular, gets love for tasting like, well, apple—reviewer Ry called it the best in the lineup, noting it’s refreshingly authentic without a chalky protein aftertaste.
For active folks, the size is a feature, not a bug; CriticalLootRNG bikes, works out, and appreciates that these bars actually feel like food.
Major outlets agree on the role: Men’s Health crowned Big 100 a best high-calorie pick, and LIVESTRONG calls it a strong meal-replacement option when you need calories and protein in one shot.
Taken together, the praise lines up: big protein, big satisfaction, flavor that doesn’t taste like a compromise.
Main Criticism
The sugar content is the lightning rod. At 29 grams, it’s closer to a fortified dessert than a low-sugar snack, which several reviewers—and Redditor im_a_dick_head, rather bluntly—flag.
Some textures run too firm for comfort, with a few buyers warning to mind your front teeth, and a minority report a faint “chemical” note common to ultra-processed bars. There are occasional quality-control gripes on Amazon—mystery hard bits, underweight bars—that don’t reflect the majority but are worth noting.
And from a nutrition lens, the fat leans on palm oils and the protein blend stacks allergens (soy, milk, egg, plus almond in this flavor), narrowing the audience.
The Middle Ground
So who’s right: the “tastes great, keeps me full” camp or the “too much sugar” camp? Probably both, depending on the job you’re asking this bar to do.
If you need an actual meal in pocket form—say, you’re between classes, stuck on a job site, or finishing a long ride—390 calories with 30 grams of protein is a smart, practical trade.
In that scenario, the sugar reads as fast fuel. If you’re just peckish at 3 p.
m. , Big 100 is a bit like bringing a marching band to a whisper-only meeting: impressive, but overkill.
Men’s Health and LIVESTRONG aren’t wrong to call it a legit meal-replacement; Eat This, Not That! isn’t wrong either to balk at using it routinely if you’re watching added sugar.
As for hardness, experiences vary—GranolaBarHero found the taste “not particularly good, not particularly bad,” while others rave; texture can drift with temperature and production runs. The fairest take: it’s a hearty, ultra-processed bar that excels at what it’s built for—big protein and quick energy—so long as you’re aligned with that mission.
What's the bottom line?
MET-Rx Big 100 Crispy Apple Pie is the protein bar for people who actually need a bar to behave like a meal. It’s substantial, it’s satisfying, and the apple-cinnamon profile lands better than most “pie” attempts in the protein aisle. The protein blend is robust and complete.
The fortification is a nice bonus. But it’s not a minimalist health food and doesn’t pretend to be: 29 grams of sugar, palm-heavy fats, and an ultra-processed build make it a strategic tool rather than an everyday staple for sugar-conscious eaters. If you’re training hard, working long, hiking, or simply prone to skipping meals, it’s a practical, tasty solution.
If you want a light, low-sugar, whole-food bar, this isn’t your match—pick something smaller and simpler. Use Big 100 when you need big fuel, and it’ll make a lot of sense.
