Why It Scores 7.8 — And The Label Line Behind Each Number
Protein quality & amount
35% of score12 g of complete egg-white protein — a genuinely complete, whole-food source, but the amount is well below the ~20 g standard and the ~20 g that maximally stimulates MPS (Moore 2009). Credited for quality and whole-food form, docked for the low amount on the most important axis.
- Protein
- 12 g (egg whites — complete protein)
Ingredient quality
30% of scoreThe whole-food benchmark: egg whites, dates, nuts, cocoa and sea salt, with no sugar alcohols, no IMO fiber and nothing artificial — so none of the GI baggage. The one thing keeping this axis from the top is the 13 g of natural date sugar; clean, but not low-sugar.
Value per gram of protein
20% of score~$2.17/bar for 12 g is about $0.18 per gram — worse per-gram than the ~20 g bars because the protein count is low, even though the sticker price is mid-range. You're paying for whole-food quality, not protein efficiency.
- Count / price
- 12-count box, ~$26
- Cost per bar
- ~$2.17
Taste & texture
15% of scoreDense, chewy and date-forward — the most polarizing texture here. Some love the real-food chew; others find it sticky and heavy. The lowest taste score among the picks, which is honest given how divisive it is.
Source-provenance & label honesty
0% of scoreNon-weighted SAC transparency gate — RXBAR is one of the most honest panels here. The 'No B.S.' five-ingredient list is exactly what's in it, and it labels the full 13 g of date sugar rather than burying it. Only knock: it's marketed as a protein bar at just 12 g.

Marketing Claims Vs. Reality
Whole-food, 'No B.S.' ingredients.
The panel is egg whites, dates, nuts, cocoa and sea salt — a genuinely short, recognizable whole-food list with no sugar alcohols, IMO fiber or artificial sweeteners. The claim is accurate and among the most honest in the category.
No added sugar.
The 13 g of sugar is entirely from dates, with none added — technically and honestly accurate. We flag, per SAC policy, that 13 g is still a high sugar load; 'no added sugar' is true, but it is not a low-sugar bar.
12 g of complete protein.
Egg white is a complete, leucine-carrying protein, so the quality claim holds — but at 12 g the amount is below the ~20 g category norm and the ~20 g that maximizes MPS (Moore 2009). Complete, yes; a full protein dose, not quite.
Gentle on digestion.
With no sugar alcohols, no maltitol and no IMO fiber, RXBAR avoids the ingredients most responsible for protein-bar GI distress. For sensitive stomachs it's genuinely one of the easiest bars here.
What Our Test Actually Found
The genuine whole-food option in a category of engineered bars
Five ingredients you can pronounce — egg whites, dates, nuts, cocoa, sea salt — with nothing synthetic. In a category built on isolates, sugar alcohols and fiber tricks, RXBAR is the real-food outlier, and that's the entire reason to buy it.
It's gentle on the gut precisely because it skips the tricks
No maltitol, no IMO fiber, no sugar alcohols means none of the bloating and distress those cause. If protein bars usually upset your stomach, RXBAR is likely the one that won't — the flip side of its lower protein and higher sugar.
12 g of protein is the honest ceiling
This is well below the ~20 g leaders and the ~20 g that maximally stimulates muscle protein synthesis (Moore 2009). It's complete egg-white protein, so the quality is real, but if your goal is protein density per bar, RXBAR simply isn't the tool — pair it with other protein or size up elsewhere.
13 g of sugar is real, even if none is added
All of it comes from dates, so there's no added sugar, but 13 g is still a meaningful load — more than any other bar here. As whole food that's fine; as a 'low-sugar protein bar,' it isn't one, and we score it honestly on that.
Full analysis: all pros & cons (8), buy if / skip if
- Genuinely whole-food: egg whites, dates and nuts, with no sugar alcohols or artificial anything
- Complete egg-white protein and a panel anyone can read in five seconds
- No GI-upsetting sugar alcohols or IMO fiber — gentle on the gut
- No added sugar and 5 g of whole-food fiber
- Honest, transparent 'No B.S.' labeling
- Only 12 g protein — well below the ~20 g standard of the bars above
- 13 g sugar (from dates) is high — fine as whole food, but not a low-sugar bar
- Dense, chewy, date-forward texture isn't for everyone
- You want genuinely whole-food ingredients you can read in five seconds
- Sugar alcohols and IMO fiber upset your stomach — this has none
- You'd rather eat real food than a lab-engineered bar
- You want ~20 g of protein per bar — this has only 12
- You want a low-sugar bar — 13 g from dates is high (even if none is added)
A five-ingredient 'No B.S.' bar: egg whites (complete protein), dates, nuts, cocoa, sea salt, with 5 g fiber and zero sugar alcohols, IMO fiber or artificial sweeteners. The honest trade-offs: just 12 g protein — below the ~20 g standard and the ~20 g that maximizes MPS (Moore 2009) — and 13 g sugar from dates (0 g added). Gentle on the gut, dense and date-forward in texture.
RXBAR is the pick for anyone who'd rather eat food than chemistry. It's a five-ingredient bar of egg whites, dates, nuts, cocoa and sea salt, with no sugar alcohols, no artificial sweeteners and no IMO fiber — which also means none of the GI baggage that comes with them. The trade-offs are real and we won't hide them: at 12 grams it carries less protein than the roughly 20-gram bars above it, and at 13 grams of sugar, all from dates, it is not a low-sugar product even though none of that sugar is added. If you value clean, recognizable whole-food ingredients and a happy gut over maximum protein and minimum sugar, it's the best bar here; if you're chasing protein density, look higher up.
The whole-food choice — best for clean ingredients and a happy gut, not for protein density.
RXBAR is for anyone who'd rather eat food than chemistry: a five-ingredient bar of egg whites, dates, nuts, cocoa and sea salt, with no sugar alcohols, no artificial sweeteners and no IMO fiber — and therefore none of the GI baggage. The trade-offs are real and we won't hide them: at 12 grams it carries less protein than the ~20 g bars above it, and at 13 grams of sugar, all from dates, it is not a low-sugar product even though none is added. If you value clean, recognizable ingredients and a gentle gut over maximum protein, it's the best bar here; if you're chasing protein density, look higher up.
If This Doesn’t Fit — Try These
04Legion Protein Bar
Legion is the pick for anyone who wants their 20 grams of protein without the artificial-sweetener-and-dye chemistry set: a complete whey and milk blend sweetened only with stevia, allulose and monk fruit, built on real chicory-root prebiotic fiber, and third-party tested by Labdoor.
02Quest Protein Bar
Quest is the bar most people should default to, and it earns that: 21 grams of genuinely complete protein from whey and milk isolate with no collagen padding, just 1 gram of sugar and 4 grams of net carbs, in flavors you can find at virtually any store.
07Built Bar Coconut
Built is the bar for when you want something that eats like a candy bar but barely touches your calorie budget: a light, marshmallowy nougat dipped in real chocolate at only about 130 calories, carrying 17 grams of complete whey-isolate protein.
Quick Answers
Why is RXBAR's protein so much lower than the other bars?
Because it uses whole-food egg whites instead of concentrated protein isolates. That keeps the ingredient list to five real foods, but it caps the protein at 12 g — versus 20-28 g in the isolate-based bars. It's the direct trade-off for being whole-food.
Is 13 g of sugar bad if it's all from dates?
It's honest but still high. None of the sugar is added — it all comes from dates — so there's no refined-sugar concern. But 13 g is the most of any bar here, so if your goal is a low-sugar bar, RXBAR isn't it. As whole food, it's fine.
Is it good for a sensitive stomach?
It's one of the best here for that. RXBAR has no sugar alcohols, no maltitol and no IMO fiber — the ingredients most responsible for protein-bar bloating and GI distress. If other bars upset your gut, this is the one most likely to sit well.
Who should actually buy RXBAR?
Someone who prioritizes clean, recognizable whole-food ingredients and a happy gut over maximum protein — as a real-food snack, it's excellent. If you're chasing 20-plus grams of protein per bar or a low-sugar macro, Legion, Quest or David are better fits.

- [1] Moore 2009 PMID 19056590 — Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men. ~20 g of high-quality protein maximally stimulated MPS after resistance exercise. RXBAR's 12 g of complete egg-white protein is quality but sub-dose, so it contributes less per bar toward maximizing the response.
- [2] Morton 2018 PMID 28698222 — A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. It's total daily protein that builds muscle. A 12 g RXBAR is a smaller contribution than a 20 g bar, so you'd need more of them (or other sources) to hit the same daily total.
- [3] Schoenfeld 2018 PMID 29497353 — How much protein can the body use in a single meal for muscle-building? Implications for daily protein distribution. Aim for ~0.4 g/kg per meal across ≥4 meals. At 12 g, RXBAR falls short of a full per-meal target for most adults, so it's a partial feeding rather than a complete one.
