RXBAR vs KIND: Which Whole-Food Protein Bar Wins?
Two of the cleanest mainstream protein bars on the shelf, head-to-head. Both deliver 12 g of protein per bar. RXBAR wins on ingredient simplicity and leanness; KIND wins on lower total sugar and a peanut-forward taste. Here's the honest, data-driven breakdown — every number below is pulled live from each product's graded fact sheet.
The short answer
RXBAR Chocolate Chip is the pick if you want the shortest, cleanest ingredient list — seven whole foods, egg-white protein, no isolate — and the leaner profile (220 cal, 2 g saturated fat). The trade-off is more total sugar (13 g), all of it from dates with zero added.
KIND Crunchy Peanut Butter Protein is the pick if you'd rather have lower total sugar (8 g), a genuine whole-peanut base, and a crunchier, candy-bar-style snack. The trade-off is a longer, more engineered ingredient list (soy protein isolate, palm kernel oil) and a heavier calorie and saturated-fat load (250 cal, 4 g saturated fat).
Protein is a wash — both are 12 g per bar. On the v3 Labelgrade scale, RXBAR scores B (77/100) and KIND scores B- (74/100); the gap is ingredient quality and saturated fat, not protein.

Where RXBAR wins
- Cleanest ingredient list. Seven whole-food ingredients — dates, egg whites, almonds, cashews, chocolate, natural flavors, sea salt — printed on the front of the wrapper. No protein isolate, no sugar alcohols, no oils added for coating. That earns it an ingredient-quality grade of B, ahead of KIND's B-.
- Leaner. 220 calories and 2 g saturated fat per bar — about 18.3 calories per gram of protein vs KIND's 20.8. If you're counting calories or watching saturated fat, RXBAR is the more efficient bar.
- Zero added sugar. Every gram of RXBAR's sugar comes from dates. If your one rule is "no added sugar," this bar passes and KIND doesn't.
- Whole-food protein. The protein is egg-white-led — a complete, recognizable source — rather than a refined soy isolate.
Where KIND wins
- Lower total sugar. 8 g per bar vs RXBAR's 13 g. RXBAR's sugar is "cleaner" (date-source, no added), but KIND's total load is simply lower — the better number if you're managing blood glucose or total carbs.
- Genuine peanut base. Whole peanuts are the literal first ingredient, not a syrup or slurry. It tastes and snaps like a peanut candy bar, where RXBAR is dense and date-forward.
- Slightly higher fiber. 5 g per bar (mostly chicory-root inulin), earning a perfect A+ fiber grade — a hair above RXBAR's already-excellent 5 g.
- No artificial sweeteners either. Like RXBAR, KIND skips sucralose, ace-K, and sugar alcohols — sweetness comes from honey, glucose syrup, and a little cane sugar.
Where it's a tie
- Protein per bar. Both list 12 g, and both clear the FDA "high in protein" claim (20%+ of the 50 g Daily Value).
- Protein density grade. RXBAR A-, KIND A- — both excellent for a whole-food bar.
- Fiber. 5 g vs 5 g — both among the highest in our bar database, both grading in the A band.
- No artificial sweeteners. Neither uses sucralose, aspartame, or sugar alcohols.
Which should you buy
Buy RXBAR Chocolate Chip if ingredient simplicity is your priority, you want the leanest bar of the two, or your single rule is "no added sugar." It's the cleaner, more whole-food choice — best as a grab-and-go protein snack when you'd otherwise reach for two eggs but can't cook. Just know the date sugar is real (13 g), even if it's natural.
Buy KIND Crunchy Peanut Butter Protein if you want lower total sugar, a peanut-forward taste with real crunch, or the slightly higher fiber. It's the more satisfying "treat that happens to have protein" — best for travel, the office drawer, or a pre-workout snack. The cost is the longer ingredient list and the heavier calorie and saturated-fat load from the palm-kernel-oil coating.
For a strict cut or post-workout speed, honestly, neither is the best tool. At 18.3–20.8 calories per gram of protein, both are whole-food snack bars, not lean protein sources. A whey shake or Greek yogurt delivers the same protein faster and at a fraction of the calories. Reach for either of these bars when convenience and a real-food ingredient list matter more than maximum protein per calorie. We dig into that trade-off in are protein bars actually healthy?
How they were graded
Both products use the v3 6-dimension Labelgrade formula (see /methodology): protein density 23% + ingredient quality 21% + saturated fat 18% + sodium 15% + sugar 15% + fiber 8%. RXBAR data from USDA FDC 2609152; KIND data from USDA FDC 2585614. Every figure on this page is read live from each product's record at build time, so the numbers can't drift out of sync with the individual fact sheets.
Frequently Asked Questions
Which has more protein — RXBAR or KIND?
It's effectively a tie per bar: RXBAR Chocolate Chip lists 12 g per 52 g bar and KIND Crunchy Peanut Butter Protein lists 12 g per 50 g bar. By density, RXBAR edges it at 23.1 g per 100 g vs KIND's 24 g per 100 g, because the KIND bar is slightly larger and carries more fat. Both clear the FDA "high in protein" threshold (20% of the 50 g Daily Value).
Which has cleaner ingredients?
RXBAR, on length and on isolate-avoidance. RXBAR's chocolate chip is seven recognizable whole-food ingredients (dates, egg whites, almonds, cashews, chocolate, natural flavors, sea salt) with no protein isolate. KIND's protein bar runs twelve ingredients and leans on soy protein isolate, palm kernel oil, glucose syrup, and added sugar to hit its macros — still free of artificial sweeteners, but a more engineered formula. RXBAR scores B on ingredient quality; KIND scores B-.
Which has more sugar, and does it matter?
RXBAR has more total sugar — 13 g per bar vs KIND's 8 g — but all of RXBAR's sugar is naturally-occurring from dates with 0 g added. KIND has less total sugar but 6 g of it is added (honey, glucose syrup, cane sugar). If you avoid added sugar specifically, RXBAR wins; if you watch total sugar load or blood-glucose response, KIND's lower total is the gentler number. Both score in the B range on the sugar dimension.
Which is better for fat and calories?
RXBAR is the leaner bar: 220 calories and 2 g saturated fat vs KIND's 250 calories and 4 g saturated fat. That works out to about 18.3 calories per gram of protein for RXBAR and 20.8 for KIND. KIND's saturated fat comes from the palm-kernel-oil coating, not the peanuts, and it's the single biggest drag on KIND's grade (C- on saturated fat vs RXBAR's B).
How do the Labelgrade scores compare?
RXBAR Chocolate Chip scores B (77/100); KIND Crunchy Peanut Butter Protein scores B- (74/100) on the same v3 6-dimension formula. They tie on protein density and fiber (both excellent), but RXBAR pulls ahead on ingredient quality and saturated fat, which is what separates the two grades. KIND counters with a peanut-forward taste and lower total sugar. Neither is a "lean protein source" the way a shake is — both are whole-food-forward snack bars.
