Promix Nutrition
Vanilla
TL:DR
In 2 Sentences
A crispy cereal‑treat style bar built from whey protein puffs and an egg‑white marshmallow binder with no high‑intensity sweeteners, delivering 15 grams of complete protein at 150 calories.
When to choose Promix Nutrition Vanilla
Best for people who want a crunchy, not‑too‑sweet, gluten‑free protein snack for pre‑workout or an afternoon pick‑me‑up, and who are fine with dairy, egg, and coconut.
What's in the Promix Nutrition bar?
Think crispy whey puffs held together by a grown‑up marshmallow, then scented with real vanilla.
Promix’s Vanilla Protein Bar leans on dairy proteins—whey isolate and concentrate in the puffs—with a little help from egg white to set the marshmallow, so you get high‑quality amino acids without much fat.
The macros skew lighter than most bars: 150 calories with modest carbs built from tapioca syrup and starch but buffered by soluble fibers, and just 4 grams of sugar without artificial high‑intensity sweeteners.
Vanilla extract delivers the namesake flavor; the marshmallow texture comes courtesy of agar and egg whites.

Protein
1515MIDMost of the 15 grams of protein come from Promix’s whey protein puffs—a blend of whey protein isolate and concentrate—with a supporting boost from egg whites in the marshmallow binder. Whey is a complete, fast‑digesting dairy protein that’s typically low in lactose at the isolate level, and egg white is also complete and lean. It’s a mid‑pack protein dose made from very high‑quality sources.
Fat
49LOWFat stays low at 3.5 grams, coming mainly from coconut oil and sunflower oil used for texture. Coconut contributes more saturated fat, while sunflower brings mostly unsaturated fats; lecithin is present only in tiny emulsifying amounts. With so little total fat, the bar eats light and won’t feel greasy.
Carbs
1620MIDThe 16 grams of carbs are built from refined cassava ingredients—tapioca syrup and tapioca starch—tempered by soluble fibers (tapioca fiber and inulin) and a touch of plant‑derived glycerin for softness. Expect quicker energy from the syrup and starch, with fiber and protein smoothing the rise rather than causing a hard crash. These aren’t whole‑grain or fruit carbs, but the fiber keeps things steadier than a candy bar.
Sugar
44MIDThe 4 grams of sugar come primarily from tapioca syrup in the marshmallow-style binder. Additional sweetness and softness come from glycerin (a plant‑based humectant) and vanilla extract, so there are no artificial high‑intensity sweeteners here. The sugars are refined rather than fruit‑based, but kept modest.
Calories
150210LOWAt 150 calories, this is a lighter entry in the bar world. Most calories come from the whey‑and‑egg protein and the digestible portion of the tapioca carbohydrates, with only a small share from fats. It fits nicely as a snack or pre‑workout bite that won’t sit heavy.
Vitamins & Minerals
Calcium lands around 10% Daily Value, largely from calcium carbonate in the whey protein puffs, with a small natural contribution from dairy. Iron and magnesium are only present in trace amounts. There’s no added vitamin premix.
Additives
Several functional ingredients shape the texture: sunflower lecithin to emulsify, glycerin to hold moisture, agar to gel the marshmallow, and soluble fibers (tapioca fiber, inulin) for body. They’re refined but common bar tools, used here without artificial colors, flavors, or high‑intensity sweeteners. If you prefer only pantry staples, this lands in the middle—more engineered than minimal, but not excessive.

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 say Promix nails the nostalgia: a light, crispy texture that nods to a marshmallow square without the syrupy crash. The sweetness reads restrained and clean, a relief for folks who avoid stevia and sucralose.
Many report it’s more filling than its petite size suggests, a tidy 150‑calorie bar that still delivers 15 grams of complete protein. Several tasters highlight the satisfying crunch as the thing that sets it apart from the usual dense, taffy‑like protein bars.
Major outlets back that up: SELF named it Best Overall, EatingWell praised the lean‑for‑15g‑protein math, and Health spotlighted the candy‑like crunch minus artificial flavors.
Main Criticism
Texture is the dividing line. Some find the whey puffs denser and drier than puffed rice, with bars that can lean crumbly or a touch chalky.
If you walk in expecting a gooey rice crispy square, you may feel misled; the resemblance is more visual than textural. Coconut oil’s flavor shows up for some palates, which can crowd out the vanilla.
A handful of reviewers also mention a noticeable protein taste and a price that feels high for the bar’s size.
The Middle Ground
Here’s the honest middle: it’s a cleaned‑up crispy treat, not a marshmallow‑glued cereal square. Whey puffs are sturdier than puffed rice, and trimming sugar and fat to stay at 150 calories naturally trades some gooeyness for a drier crunch.
If you care most about avoiding high‑intensity sweeteners, want something that won’t sit heavy before a workout, and enjoy a cereal‑bar snap, this hits the brief. If your ideal bar is soft and sticky, or you’re sensitive to coconut notes, you may land with the folks calling it dry or sunscreen‑adjacent.
Health editors flagged potential sensitivities to inulin and fiber syrups; if that’s you, start with half a bar to test tolerance. And for the record, despite one exuberant online review elsewhere, this flavor isn’t vegan; it’s built on dairy and egg.
Expect a tidy, crunchy, not‑too‑sweet experience rather than a dessert bar.
What's the bottom line?
Promix’s Vanilla Protein Puff Bar threads a careful needle: 15 grams of complete protein in a light, crunchy format with modest sugar and no high‑intensity sweeteners. It’s genuinely snackable, especially if you prefer clean, cereal‑bar textures over dense brownie bricks, and it slots neatly as a pre‑workout or mid‑afternoon bite. The trade is texture.
Compared with a true marshmallow square, this leans drier and can crumble, and coconut does peek through. Ingredient‑wise it’s gluten‑free and vegetarian, but it does contain milk, egg, and coconut. If you’re chasing a nostalgic crunch and steady macros, this is an easy yes.
If you want a gooey dessert bar or have a coconut aversion, you’ll likely be happier elsewhere. Condensed listicle take: The grown‑up crispy treat.
Crunchy, not too sweet, and free of high‑intensity sweeteners with 15g protein at 150 calories. Occasionally dry and coconut‑forward; best for pre‑workout snackers who can do dairy, egg, and coconut.
