MET-Rx
Chocolate Chip Granola
TL:DR
In 2 Sentences
A true meal‑replacement‑scale bar: a layered Metamyosyn protein blend (soy crisps + whey + milk proteins + a touch of egg) with real oats and seeds, chocolate, and multivitamin‑level fortification.
When to choose MET-Rx Chocolate Chip Granola
Best for training days, long commutes, and anyone who needs a filling, on‑the‑go mini meal—not for those seeking a light, low‑sugar nibble.
What's in the MET-Rx bar?
MET-Rx’s Chocolate Chip Granola bar eats like a chocolate‑studded granola slab but performs like a mini meal.
Its protein backbone is a mixed “Metamyosyn” blend anchored by soy protein crisps (soy protein isolate) with fast whey protein isolate, slow‑release milk proteins (milk protein isolate/concentrate and casein), and a touch of egg white.
On the macros slide it sits near the top for protein and even higher for carbs and calories—think workout fuel or a hold‑you‑over option, not a dainty snack.
The granola personality comes from rolled oats, brown rice flour, and a trio of almonds, pumpkin seeds, and sunflower seeds, while the chocolate flavor is real (unsweetened chocolate, cocoa butter, cocoa).
Sweetness and chew are driven by tapioca syrup and sugar, supported by glycerin and a sugar alcohol, and the label is fortified like a multivitamin with a sweep of B‑vitamins, A, C, D, E, zinc, and copper.

Protein
2815HIGHThis bar’s 28g of protein come from a layered blend: soy protein crisps (soy isolate) for structure, plus whey protein isolate and milk proteins (milk protein isolate/concentrate and casein) with a bit of egg white. That mix combines fast‑digesting whey with slower casein and complete plant protein, yielding a robust amino acid profile and good satiety. It’s dairy‑ and soy‑forward, so it’s high quality but not suitable for those avoiding either allergen.
Fat
119MIDFat lands in the middle of the pack and comes from a mix of whole foods and processed oils: almonds and seeds (sunflower, pumpkin) provide unsaturated fats and vitamin E, while fractionated palm kernel oil, milkfat, and cocoa butter add more saturated fat for structure and chocolate snap. Canola and sunflower oils round it out with additional unsaturated fat. Net-net, expect a blend that skews more saturated than a nut‑butter‑only bar but still includes heart‑friendly fats from the nuts and seeds.
Carbs
4820HIGHCarbs are high and largely built on refined binders—tapioca syrup/solids and sugar—plus glycerin for chew, with polydextrose adding some fiber. Rolled oats and brown rice flour contribute whole‑grain carbs and a little fiber, but the overall profile leans quick‑burn energy rather than slow, steady release. The substantial protein and fat will blunt the spike somewhat, yet this is still a fast‑fuel bar by design.
Sugar
144HIGHSugar sits on the higher side for a protein bar and comes primarily from sugar and tapioca syrup (plus a bit from chocolate and dairy), not fruit. Some sweetness is offloaded to a sugar alcohol (maltitol) and glycerin, which reduce labeled sugars but still add carbohydrate and can bother sensitive stomachs in larger amounts. It’s sweet and dessert‑leaning—plan it where it makes sense in your day.
Calories
390210HIGHCalories are notably high for a single bar because you’re getting big portions of all three macros: a top‑tier protein dose, a large hit of syrup‑based carbs, and moderate fat from oils, chocolate, and nuts/seeds. Think of it as a portable mini‑meal or training fuel rather than a light snack. If you’re watching intake, consider splitting it or pairing half with something fresh.
Vitamins & Minerals
Fortification is prominent: expect about 25% Daily Value for vitamins A, C, D, E and several Bs, with minerals like zinc (~35% DV) and copper (~60% DV) standing out. Most of this comes from the added vitamin‑mineral blend, with smaller natural contributions from dairy and seeds (vitamin E) and oats (minerals). It eats a bit like a multivitamin in bar form.
Additives
To get that chewy, shelf‑stable granola‑bar texture, the formula leans on refined helpers: glycerin (holds moisture), polydextrose (added fiber for body), a sugar alcohol (maltitol) for bulked sweetness, soy lecithin for emulsifying, and fractionated palm kernel oil for structure. These are common in confection‑style protein bars and are safe at food levels, but the polyol can cause GI discomfort for some at higher intakes. Overall, it’s more engineered than a simple nuts‑and‑dates bar.

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 doesn’t play small. Across Reddit and Amazon, the consistent refrain is high protein that actually keeps you full, with many calling it a reliable meal replacement for busy days or post‑workout recovery.
Active folks—like the cyclist who also lifts—say the calories work in their favor and the size feels substantial rather than snacky.
Flavor praise pops up frequently, from Salted Caramel Brownie Crunch to a surprisingly “real” apple note in the Apple variety, and the texture often earns points for being crispy‑chewy rather than taffy‑like.
Even third‑party roundups back the positioning: Men’s Health names Big 100 a best high‑calorie bar, and LIVESTRONG highlights it for weight gain and refueling needs. Add in an average Amazon rating around 4.
5 stars across many thousands of reviews, and you have a bar that clearly delivers for people who want a portable, protein‑forward mini meal.
Main Criticism
The flip side of that dessert‑leaning satisfaction is sweetness. Several reviewers point out added sugar in the 20–29 gram range depending on flavor, which won’t suit everyone’s day.
A few call certain flavors overly sweet or a bit artificial, and some note occasional chalkiness—that classic protein‑bar gripe.
Texture can be polarizing, too: a handful of buyers found their bars firmer than expected (even tough on front teeth), and there are sporadic quality‑control complaints about hard chunks or underweight bars.
Finally, because sweetness and chew are helped along by sugar alcohols, sensitive stomachs may notice it if they’re already prone to GI discomfort.
The Middle Ground
When you frame Big 100 as a mini meal, the macro math checks out: 28 grams of protein in this flavor, high carbs for quick fuel, and moderate fats to keep you satiated.
That’s why it shines for heavy training days, manual‑labor mornings, or long stretches without a real sit‑down meal. The sugar caveat is fair—Men’s Health flags it, and Redditor im_a_dick_head put it less delicately—but the blend of protein and fat does soften the ride compared with a candy bar.
On taste, you’ll see a spectrum: some flavors win real fandom, while others get the “meh” treatment (shoutout to GranolaBarHero for the diplomatic review) or are flat‑out disliked by a minority.
The quality‑control gripes are worth watching, though they appear to be the exception, not the rule, given the wide base of satisfied buyers.
The truth sits here: if you want a low‑sugar, whole‑food bar, this isn’t it; if you need reliable calories and big protein in one wrapper, this bar does its job—and does it with a granola‑meets‑chocolate personality that many actually enjoy.
What's the bottom line?
MET-Rx Big 100 Chocolate Chip Granola is the definition of context matters. Treat it like a snack, and it may feel too big, too sweet, and too engineered. Treat it like a portable mini meal, and its strengths snap into focus: a robust multi‑protein blend, real granola ingredients for character, and enough carbs and calories to meaningfully fuel training or tide you over until dinner.
It won’t be the right pick if you avoid soy or dairy, if you prefer minimally processed bars, or if added sugar and sugar alcohols don’t fit your plan. But for athletes, commuters, students, and anyone with long days who needs sustained energy in a single wrapper, it’s a practical, tasty tool. Keep expectations honest—this is a big, dessert‑leaning bar by design—and it can be a strategic win.
And if you’re worried about the firmness some folks mention, pairing it with coffee or water and not storing it in the cold helps. Split it in half when you want a lighter lift; go all‑in when the day demands more.
