RXBAR
Peanut Butter
TL:DR
In 2 Sentences
A short, recognizable ingredient list with no artificial sweeteners or sugar alcohols; egg whites provide complete, highly digestible protein while dates sweeten and bind.
When to choose RXBAR Peanut Butter
Reach for it when you want a real‑food snack or a pre/post‑workout bridge with a ~2:1 carbs‑to‑protein ratio. Great for those avoiding sugar alcohols and gluten, but not for vegans or anyone avoiding peanuts or eggs.
What's in the RXBAR bar?
RXBAR Peanut Butter keeps things simple: dates for sweetness, peanuts for flavor and healthy fats, and egg whites for the protein backbone. The protein comes primarily from egg whites—clean, complete, and highly digestible—boosted by peanuts and peanut flour for that unmistakable PB chew.
Because the bar leans on whole dates to bind and sweeten, sugars and carbs land higher than most protein bars, while calories and fat stay modest and the ingredient list remains refreshingly short.
Peanut flavor is built from real peanuts and peanut flour, nudged along by a pinch of natural flavor. If you want a fruit-sweetened, peanut-forward bar with straightforward ingredients, this reads more like a whole-food energy bar with a solid protein assist than a max-protein heavyweight.

Protein
1215MIDProtein here comes from a simple duo: pasteurized egg whites plus peanuts/peanut flour. Egg whites deliver complete, highly digestible protein, while peanuts add a plant-protein bump and that classic PB chew. At 12g, it’s lighter than many protein-first bars, but the protein quality is excellent.
Fat
79MIDAll 7g of fat are peanut-derived—mostly heart-friendly monounsaturated fats, with a bit of polyunsaturated and some saturated. There are no added oils here, just the fat that naturally comes with peanuts. It’s enough to add flavor and satiety without weighing the bar down.
Carbs
2420MIDMost of the 24g of carbs come from whole dates, which both sweeten and hold the bar together. You get some fiber and minerals with those natural sugars, yet the overall load skews toward quick, ready energy rather than a long, slow release. If you’re sensitive to spikes, enjoy it pre-workout or pair it with extra protein or dairy/yogurt.
Sugar
174HIGHThe 17g of sugar come almost entirely from dates—the whole fruit, not refined syrups. That means a bit of fiber and minerals in the mix and no artificial sweeteners or sugar alcohols, but it’s still one of the sweeter bars on shelves. If you’re watching sugars, timing it around activity helps it work for you.
Calories
190210MIDAt 190 calories, it sits on the lighter side for the category. Most calories come from the dates’ carbohydrates, with peanuts contributing a smaller share from fats and some from protein. In practice, it behaves like a fruit-sweetened energy bar that still delivers a respectable protein assist.
Vitamins & Minerals
No nutrients clear the 10% daily value mark. You do get a modest bump of potassium (about 8% DV) from dates plus small amounts of calcium and iron, with peanuts contributing trace vitamin E that isn’t listed. Think macronutrients first, micronutrients second.
Additives
This is a short, clean label: dates, peanuts, egg whites, peanut flour, sea salt, and natural flavors. The natural flavor simply rounds out the peanut profile; there are no emulsifiers, syrups, or sugar alcohols. Processing is minimal, leaning on whole foods to do the heavy lifting.

What are people saying?
Sources
Range
“I usually buy the RX Bars. It’s one of the few protein bars and I found that does not have “fake” or alcohol sugars. Those sugars always leave a bad taste in my mouth. I end up having an RX Bar pretty much every day for breakfast.”
“I got hooked on the RX bars a few years back. While they lag in protein then make up for it with their ingredients.”
“I have moderate/ severe IBS. The RX Bars are fantastic, they taste great and I have produce no side effects for me.”
Main Praise
Fans come back to RXBAR Peanut Butter for what it doesn’t do as much as what it does: no sugar alcohols, no syrups, no long ingredient paragraph—just straightforward foods that many stomachs tolerate well.
Several reviewers note it’s a dependable breakfast or between‑meal standby, the kind you can eat daily without the metallic aftertaste some sweeteners leave behind. Healthline, Men’s Health, and Good Housekeeping all tip their caps to the brand’s whole‑food approach and balanced macros, calling it a best‑overall pick in different contexts.
The peanut flavor is legit because it’s built on peanuts and peanut flour, and the egg‑white protein is high‑quality even if the total protein is a modest 12g. People also praise the steady energy—unsurprising given the dates—and the satisfying, peanut‑butter‑meets‑fudge chew when you’re in the mood for it.
Main Criticism
Texture is the sticking point—literally. A slice of reviewers find RXBARs tough, overly chewy, and inclined to lodge in your teeth; one colorful Amazon reviewer likened a bar to leather.
Others say the flavor can read as muted or just okay compared with dessert‑leaning bars, especially if you expect candy‑bar sweetness.
At 12g of protein, it won’t satisfy lifters chasing 20g‑plus in a single bar, and the 17g of sugar from dates makes it one of the sweeter options on shelves, which some folks watching sugar would rather avoid.
A few also feel the bar eats small for the calories and may want two if hunger is high.
The Middle Ground
So where does the truth land? If you like real‑food bars and avoid sugar alcohols, this is a clear win.
Redditor On‑The‑Rails eats one for breakfast most days specifically because there’s no artificial aftertaste, and even Healthline and Men’s Health highlight the simple formula and smart carb‑to‑protein ratio (about 24g to 12g here) for training days.
But texture is polarizing: user BadNoodleEggDemon warned about the dental cling, while TipT0pMag00 called the taste “just okay”—fair if you’re expecting candy. The chew is largely the point of a date‑bound bar; if you enjoy a dense, peanut‑buttery, almost fudge‑like bite, you’ll be pleased.
If not, a softer bar or a crispy wafer style will treat you better. And while one Redditor with IBS reported no issues, it’s worth noting that tolerance is individual—some folks react more to sugar alcohols (not present here), others to certain fruits.
Practical tip from the crowd: a warm drink alongside softens the bite and makes the experience downright cozy.
What's the bottom line?
RXBAR Peanut Butter is a whole‑food‑leaning bar that keeps its promises: short ingredient list, complete protein from egg whites, real peanut flavor, and steady, date‑driven energy. It’s not trying to be a 20‑something‑gram protein brick or a low‑sugar dessert dupe; it’s a tidy 190‑calorie snack with 12g of protein, 7g of peanut‑sourced fats, and 24g of carbs that does its best work before or after activity—or as a clean snack when you want something you can actually pronounce. If you love a dense, chewy PB bar and prefer sweetness from fruit instead of additives, this is an easy yes.
If you want maximum protein per bite, ultra‑soft texture, or very low sugar, it won’t be your hero. Consider it the honest friend in your snack drawer: straightforward, supportive, and refreshingly drama‑free—as long as you’re okay picking the occasional peanut‑date crumb from your teeth.
