Promix Nutrition
Matcha
TL:DR
In 2 Sentences
A rice‑crispy‑inspired protein bar without sugar substitutes, using crisped whey puffs and real Japanese matcha for a subtly grassy, lightly sweet flavor (with a small caffeine nudge).
When to choose Promix Nutrition Matcha
Reach for it as a light pre‑workout or afternoon pick‑me‑up when you want crunch over goo, subtle sweetness over frosting, and a gluten‑free option; skip it if you avoid dairy, eggs, or coconut.
What's in the Promix Nutrition bar?
Promix Nutrition’s Matcha Protein Bar builds its crunch around whey protein puffs—whey isolate and concentrate formed into airy crisps—then binds it with a marshmallow made from cassava‑derived syrup and fiber, a touch of glycerin, and whipped egg whites.
You get 15g of complete, fast‑digesting dairy protein at a middle‑of‑the‑pack level, 18g carbs drawn mostly from refined tapioca syrup/starch with some soluble fibers mixed in, and just 2g fat for a very light 140‑calorie bite.
Japanese matcha and vanilla deliver the green‑tea flavor (and a hint of caffeine), while a little coconut oil helps the texture set.

Protein
1515MIDMost of the 15g protein comes from Promix’s whey puffs—built from whey isolate (very low lactose, high leucine) plus whey concentrate—supported by a smaller contribution from egg whites in the marshmallow. That combo delivers a complete, quickly absorbed amino acid profile and lands about mid‑pack for protein among bars. If you’re lactose‑sensitive, the isolate helps, but it’s still a milk‑and‑egg bar.
Fat
29LOWOnly 2g fat, mainly from a small addition of coconut oil to set the texture; that’s largely saturated fat, but the amount is tiny. There are no seed oils here; sunflower lecithin appears in trace amounts as an emulsifier. Very low fat keeps calories light but offers less slow‑burn satiety than nut‑ or olive‑oil‑based bars.
Carbs
1820MIDThose 18g of carbs lean more “refined” than “whole‑food.” The binding comes primarily from tapioca syrup (a cassava‑based glucose syrup) and a bit of tapioca starch for structure, tempered by soluble fibers—tapioca resistant dextrin and chicory‑root inulin—and some glycerin for moisture. Expect quicker energy upfront, with the fiber and protein helping smooth the curve compared with a candy‑style bar.
Sugar
44MIDAbout 4g sugar per bar, primarily from the tapioca syrup used to make the marshmallow binder. The rest of the sweetness and chew comes from plant‑derived glycerin and soluble fibers, which are refined ingredients rather than fruit. If you prefer fruit‑sweetened bars, this one leans engineered; if you want sweetness without a sugar bomb, it fits the brief.
Calories
140210LOWAt 140 calories, this sits at the very low end for protein bars. Most of the energy comes from the protein–carb pairing, with little from fat, so it shines as a light snack or pre‑workout nibble rather than a meal replacement.
Vitamins & Minerals
No standout vitamins or minerals cross the 10% daily value mark. A little calcium likely comes from calcium carbonate in the whey puffs and from the dairy proteins themselves, but this isn’t a fortified bar.
Additives
Texture is built with a small toolkit: agar (a seaweed‑based gelling agent for the marshmallow), sunflower lecithin to help fats and water mix, glycerin to keep it soft, and soluble fibers from cassava and chicory. These are fairly refined but used in modest amounts to create a low‑sugar, puffy bar without artificial sweeteners. Expect more food‑science finesse than a date‑and‑nut base.

What are people saying?

Range
“I love these ProMix Protein Puff Bars. They taste kind of like a rice crispy bar. The chocolate chip is great. I also like the coconut, though the chocolate chip are better. I haven’t yet tried the other flavors.”
“I actually really like the promix bars because they don't taste super sweet (and I hate bars with artificial sweetener). I also find them more filling than other bars, probably bc they're not too sweet.”
“The promix are a little more bang for your calories”
Main Praise
Fans highlight three things: texture, sweetness restraint, and the protein‑to‑calorie ratio. The crisped‑whey build lands more like a grown‑up cereal treat than a sticky bar, and several Redditors appreciated that it isn’t cloying or laced with artificial sweeteners.
A few even found it more satiating than sweeter bars, likely because it’s not a sugar rush that fizzles. Editors agree: outlets like SELF and EatingWell praised the nostalgic crunch and the way it satisfies without a funky aftertaste.
Add the tidy 15g of protein in a 140‑calorie package, and you’ve got a pre‑gym or between‑meeting snack that doesn’t sit heavy.
Main Criticism
Not everyone gets along with the texture.
Some reviewers call it dry or a bit chalky, and a few were surprised that the puffs can feel firmer than airy puffed rice—especially if they expected full Rice Krispies nostalgia.
Taste can polarize, too: coconut oil’s aroma peeks through for sensitive palates, and one Amazon reviewer felt the protein note was too prominent. Health’s testers also flagged that inulin (a chicory‑root fiber) can bother sensitive stomachs.
Finally, some publications noted price can feel premium depending on where you buy it.
The Middle Ground
So who’s right—the crispy‑bar converts or the disappointed Krispies purists? Both, honestly.
If you’re chasing gooey marshmallow pull, this bar doesn’t go there; it’s intentionally airy‑crisp and lightly bound, which reads as “dry” to some and “clean crunch” to others. The flavor philosophy leans subtle: real matcha brings a gentle, grassy‑vanilla vibe rather than dessert‑level sweetness.
One Redditor grumbled that the puffs were larger and harder than expected; that’s fair if you’re picturing puffed rice. Think cereal‑bar crunch with protein heft, not bake‑sale squish.
On the nutrition front, expect more food‑science finesse (cassava‑derived syrups and fibers, glycerin, agar) than a date‑and‑nut brick, but also no artificial sweeteners. Sensitive to chicory fiber?
Start with half and see how you feel. Want a pre‑workout nibble that won’t coat your mouth in syrup?
This is squarely in your lane.
What's the bottom line?
Promix’s Matcha Protein Puff Bar is a smart pick if you like your snacks crisp, subtle, and efficient: 15g protein, 140 calories, and 4g sugar without the typical artificial sweeteners. The matcha note is gentle, the sweetness restrained, and the overall experience skews cereal‑bar‑meets‑gym‑snack rather than dessert. It’s not perfect.
Some palates find it drier or a touch chalky, and the coconut aroma plus chicory‑root fiber won’t suit everyone. But if you want a light, gluten‑free bar that delivers protein without feeling heavy—and you prefer crunch over goo—this is an easy yes. If you want a soft, sticky treat or a fruit‑sweetened ingredient list, keep looking.
