Peanut Butter Crunch
TL:DR
In 2 Sentences
A whey-forward, low-sugar peanut bar with an unusual Brain Blend (lion’s mane, citicoline, ashwagandha, vitamins) packed into a tidy 170 calories.
When to choose Mosh Peanut Butter Crunch
Snackers who want a not-too-sweet, gluten-free, peanutty bite between meals or pre‑workout and prefer dairy protein. Less ideal if your target is a 20g protein bar.
What's in the Mosh bar?
Meet Mosh’s Peanut Butter Crunch: a whey-based bar built on dairy proteins and real peanuts, with a surprisingly light 170-calorie footprint.
The protein comes from a trio of refined dairy stars—whey isolate, whey concentrate, and milk protein isolate—while the classic peanut-butter taste and crunch come straight from peanuts, a pinch of sea salt, and a little cocoa butter for creaminess.
Carbs lean more “engineered for steadiness” than “oats and dates,” thanks to soluble tapioca fiber, a touch of tapioca starch, and plant-derived glycerin, and the sweetness lands mostly from stevia and monk fruit, not sugar (just 1 gram).
The fat is middle-of-the-road and mostly peanut-derived, with some cocoa butter mixed in. If you’re curious about the added brainy extras—lion’s mane, citicoline, ashwagandha—they’re cameo players on the nutrition label, not the drivers of the macros.

Protein
1215MIDProtein here is all dairy: whey protein isolate and concentrate plus milk protein isolate (the casein+whey combo). That means complete, highly digestible amino acids with relatively low lactose compared with milk, though it still contains a milk allergen. At 12g, the protein lands on the lighter side for bars, but the quality of the whey-heavy blend is top-notch for muscle repair and satiety.
Fat
99MIDMost of the 9g of fat comes naturally from peanuts—rich in monounsaturated fats—with some cocoa butter adding a firmer texture and a bit of stearic acid (a saturated fat that’s relatively neutral for LDL). There’s no heavy use of refined seed oils here; sunflower lecithin shows up in tiny amounts as an emulsifier, not a major fat contributor. The result is a moderate, satisfying fat profile that helps keep you full.
Carbs
1820MIDThese carbs skew ‘clean-engineered’ rather than whole-grain: soluble tapioca fiber (a manufactured resistant dextrin) does much of the lifting, with smaller roles for tapioca starch and plant-derived glycerin, plus a touch of agave. Expect a steadier energy curve than you’d get from straight sugar thanks to the fiber, though the tapioca starch portion is quickly digested. If your gut is sensitive, know that larger doses of resistant fibers can cause gas for some people.
Sugar
14LOWSugar stays very low at 1g because sweetness mostly comes from stevia leaf extract and monk fruit—both high‑intensity sweeteners used in tiny amounts—alongside mildly sweet glycerin. The bit of organic agave contributes some real sugar, but not much. Low sugar doesn’t mean bland; it means the bar relies on refined, calorie-light sweeteners to keep blood sugar steadier than a syrup-forward bar.
Calories
170210LOWAt 170 calories (low for the category), this bar spreads energy across peanuts and cocoa butter (fat), a modest 12g of dairy protein, and fiber‑heavy carbs. Because a chunk of the carbohydrate is non‑digestible fiber, you’re not getting a sugar surge for those calories. It’s a tidy snack-size bar rather than a full meal replacement.
Vitamins & Minerals
You get about 15% of daily vitamin D, which is added as vitamin D3 in the brand’s ‘Brain Blend.’ Calcium carbonate shows up too, but the listed calcium is only 4% DV, so it’s more of a supporting act. Vitamin B12 is included in the blend, though not at a level flagged above 10% DV on this flavor’s label.
Additives
Expect a functional-bar toolkit: soluble tapioca fiber (a refined, fermentable fiber) to lower net carbs, vegetable glycerin to keep it soft, sunflower lecithin for smooth texture, and high‑intensity sweeteners (stevia, monk fruit) to cut sugar. The cognitive ‘Brain Blend’ (citicoline, lion’s mane, ashwagandha) adds a supplemental angle without moving the macros. Overall, more refined than a whole‑food bar, but each additive serves a clear purpose—texture, stability, or sweetness with minimal sugar.

Main Praise
Fans tend to rally around the balance: it’s a genuinely snack-size bar that feels satisfying without tipping you into a sugar slump. The whey-first protein blend earns points from people tired of gritty plant bars, and the peanut crunch reads as real food, not puffed filler.
Major outlets have also been kind to the line: SELF gave MOSH a 2025 Pantry Award, EatingWell highlighted its convenience and low sugar approach, and Health praised the texture and macro mix.
On Amazon, several reviewers appreciate that the brand sticks with whey and keeps calories in check, calling it a solid everyday option rather than a dessert masquerade. The overall theme from happy customers is consistency: steady energy, pleasant chew, and flavors that don’t blast you with syrupy sweetness.
Main Criticism
The biggest knocks come in three flavors: price, protein, and palate. Some Redditors and Amazon buyers think it’s expensive for the size and for 12g of protein—more “health bar” than heavy‑hitting protein bar.
Taste is polarizing across the brand: a portion of reviewers report dryness or a lingering sweetener aftertaste, especially in fruit flavors, and a few describe a chemical note they can’t un-taste.
There’s also skepticism about the Brain Blend—doses aren’t disclosed in a way that lets you gauge effect, and some viewers of the Shark Tank segment felt the brain‑health language outpaced the evidence.
In short, if you want 20g of protein and a brownie-like experience, this isn’t that.
The Middle Ground
So is MOSH Peanut Butter Crunch a candy bar in disguise, as one Reddit skeptic joked? The macros say no: 1g of sugar, a real whey blend, moderate fats largely from peanuts, and fiber‑heavy carbs point to a deliberately restrained build.
But it’s also true that 12g of protein at 170 calories won’t satisfy someone chasing a post‑lift 20g hit; as user chatter suggests, it’s a snack, not a meal replacement. On taste, the divide makes sense—using stevia and monk fruit keeps sugar low, but those sweeteners can leave an aftertaste for some.
And the Brain Blend is best seen as a garnish: the ingredients are interesting, yet the bar doesn’t claim disease prevention and the amounts aren’t positioned like a supplement. If your stomach is finicky with refined fibers, you may also want to test one bar before stocking up—resistant fibers can bloat sensitive folks.
The truth sits in the middle: a thoughtfully engineered snack with a cleanish label for the category, not a miracle or a mess.
What's the bottom line?
MOSH Peanut Butter Crunch is a smart pick for people who want a restrained, peanut‑forward bar with quality dairy protein, steady‑feeling carbs, and almost no sugar. It’s comfortable in that mid‑morning, pre‑meeting, or commute slot where you want something real enough to satisfy but light enough to keep you moving.
If you’re price‑sensitive, sensitive to high‑intensity sweeteners, or you refuse to buy a bar under 18–20g of protein, you’ll likely be happier elsewhere. But if a 170‑calorie, gluten‑free, not‑too‑sweet peanut bar sounds like your pace—and you’re curious about the extra vitamins and botanicals without expecting miracles—this one earns a spot in the snack rotation.
