Promix Nutrition
Banana Bread
TL:DR
In 2 Sentences
A crispy, marshmallow-style bar built from whey-protein puffs—no artificial sweeteners, just a cereal-treat crunch with a lean 150-calorie, 15-gram protein profile.
When to choose Promix Nutrition Banana Bread
Reach for it when you want a light, pre- or post-workout snack with real crunch and no sugar substitutes—especially if you’re gluten-free and fine with dairy, egg, and coconut.
What's in the Promix Nutrition bar?
Promix’s Banana Bread Protein Bar is built around crisp whey-protein puffs (a blend of whey isolate and concentrate) bound with a marshmallow-style layer that uses egg whites and agar for lift, then finished with a chocolate drizzle and a little coconut.
It’s a leaner-than-usual bar on calories and fat, with carbs coming from a mix of quick hitters (tapioca syrup and starch) and gentle, soluble fibers (tapioca resistant dextrin and inulin). One small surprise: despite the Banana Bread name, there’s no banana on the label—the cozy bakery vibe seems to come from vanilla, the marshmallow sweetness, and that cocoa-kissed drizzle.

Protein
1515MIDThe 15 grams of protein come primarily from whey protein isolate and concentrate in the crunchy puffs, with a supporting boost from egg whites in the marshmallow layer. Whey isolate is a clean, highly filtered dairy protein that’s rich in leucine and typically low in lactose, while egg white is another top‑tier, complete protein. Together they deliver an efficient, fast‑to‑moderate digesting amino acid profile that sits around the middle of the pack for bars by quantity, but high by quality.
Fat
49LOWMost of the fat traces back to tropical oils: palm kernel oil in the chocolate drizzle plus organic coconut oil and coconut flakes. These are largely saturated fats; however, the total fat is quite low, so the overall saturated load is modest. You won’t find heart‑healthy oils like olive or nut butters here, but with only a few grams of fat, this bar stays light.
Carbs
1720MIDCarbs are a blend of refined binders and fibers: tapioca syrup and tapioca starch provide quick energy, while soluble tapioca fiber (a resistant dextrin) and inulin add non‑digestible carbs that slow things down a touch. Expect a faster rise in energy than a bar built on oats or dates, tempered somewhat by the fibers and protein. It’s more “cleanly formulated candy‑bar energy” than whole‑grain sustained fuel.
Sugar
54MIDSugar sits at 5 grams, largely from cane sugar in the drizzle and tapioca syrup in the marshmallow. There are no high‑intensity sweeteners; some of the sweetness and softness come from glycerin, a plant‑derived humectant that isn’t counted as sugar, plus soluble fibers that add body. Net effect: sweet but not syrupy, with most sweetness from refined, not fruit‑based, sources.
Calories
150210LOWAt 150 calories, this is a lighter bar than most. Calories are split mainly between protein and carbohydrates, with only a small contribution from fat. That balance makes it useful as a snack or pre‑workout bite when you want protein without a heavy, high‑fat feel.
Vitamins & Minerals
You get about 13% of daily calcium, thanks mainly to added calcium carbonate in the whey puffs (and a little naturally from dairy proteins). Iron and potassium show up in smaller amounts, likely contributed by cocoa and the broader ingredient mix, but calcium is the only standout.
Additives
The label uses a handful of functional helpers: sunflower lecithin (emulsifier), glycerin (keeps the bar soft and moist), agar (a seaweed‑derived gelling agent), and isolated fibers like tapioca resistant dextrin and inulin. These are refined, purpose‑built ingredients common in bars, used here to bind the puffs, create a marshmallow texture, and maintain shelf stability. It’s not a whole‑food‑only formula, but it avoids artificial sweeteners and keeps the additive list relatively focused.

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 consistently celebrate the texture and the restraint. Multiple reviewers—from SELF to EatingWell—call out the nostalgic, crispy bite that evokes a rice crispy treat without the syrupy sweetness or artificial aftertaste.
Redditors echo that it hits a satisfying middle ground: sweet enough, but not cloying, and noticeably more filling than many candy-bar-style options, perhaps because it isn’t blasting your palate with sweeteners.
The macro math is another win: 15 grams of protein for roughly 150 calories is efficient “bang for your calories,” as one user put it. And for people who steer clear of sucralose or stevia aftertastes, the simple, refined-sugar approach is a relief.
In short, it’s light, crunchy, and easy to digest before a workout.
Main Criticism
Where the Promix bar loses some folks is texture expectations and flavor nuance. Several reviewers note it’s not actually a gooey rice crispy treat—more crisp and a bit dry, with puffs that can feel larger or harder than expected.
A few Amazon reviewers found a faint chalky or protein-y aftertaste, and some called the bar crumbly. The coconut elements can show up in aroma and taste more than anticipated, which is polarizing if you’re not a coconut person.
Others felt the Banana Bread name sets a flavor promise the ingredient list doesn’t keep—no banana, and the profile leans more vanilla-chocolate-coconut than bakery loaf.
The Middle Ground
So which is it—craveable or cardboard? The truth sits in the middle.
If your mental picture is a sticky, marshmallow-melded square, you’ll likely side with the Amazon reviewers who called it dry or dense. But if you want a cereal-bar crunch that skips artificial sweeteners and still delivers 15 grams of high-quality protein, you’ll probably land with SELF’s testers who crowned it a favorite.
The slight dryness tracks with its lean build: modest fat, lots of airy puffs, and fibers that hold things together without turning it into fudge. Coconut does peek through for some palates; EatingWell flagged that, and it’s worth noting if you’re sensitive to coconut aroma.
And yes, Redditor complaints about “harder puffs” aren’t imaginary—these are whey puffs, not rice, so the crunch is different by design. Even Eric, the certified nutrition coach on Amazon who couldn’t finish his bar, might agree the formula is aiming for crisp efficiency over gooey nostalgia.
What's the bottom line?
Promix’s Banana Bread Protein Puff Bar is a smart choice if you want a light, crunchy, no–artificial-sweetener snack that still packs 15 grams of complete protein. It feels more like a protein-forward cereal treat than a dessert bar: quick, tidy energy from refined binders and fibers, a cocoa-kissed drizzle, and a clean finish that many find easier on the palate than hyper-sweet alternatives. Expect vanilla-chocolate-coconut more than true banana bread, and a texture that leans crisp over gooey.
If dryness or coconut isn’t your thing, pick a different flavor—or pair it with coffee and move on with your day. Condensed listicle takeaway: A crispy, marshmallow-style bar with 15 grams of protein at 150 calories and no artificial sweeteners. Great pre-workout or anytime you want crunch without a sugar-substitute aftertaste; skip it if you demand gooey or dislike coconut.
